Big-Ip Access Policy Manager is affected by user interface (ui) misrepresentation of critical information (CVSS 3.1).
Denial of service in F5 BIG-IP allows remote, unauthenticated attackers to terminate the Traffic Management Microkernel (TMM) and disrupt data-plane traffic processing. The flaw is a double-free (CWE-415) triggered by undisclosed network traffic, but exploitation is gated by a hardware precondition: the BIG-IP system must run on a multi-bladed chassis platform with more than one active blade, so single-blade and standard appliance deployments are not described as affected. No public exploit code has been identified at time of analysis, KEV status is not indicated, and EPSS is low at 0.35% (27th percentile); nevertheless, a TMM crash on a production load balancer can cause an immediate traffic outage. Vendor advisory: K000156912.
Denial of service in F5 BIG-IP allows remote, unauthenticated attackers to terminate the Traffic Management Microkernel (TMM) and disrupt traffic handling, but only on systems where IPsec is configured - deployments without an IPsec configuration are not exposed. The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:N/UI:N with VC:N/VI:N/VA:H) and the corresponding CVSS 3.1 assessment agree that the effect is purely availability loss (a TMM crash), with no confidentiality or integrity impact, which makes this a high-severity (8.7) but non-compromising availability issue against appliances that are common internet-facing edge devices. No public exploit code and no confirmed active exploitation were identified at time of analysis, and the EPSS score of roughly 0.37% (29th percentile) indicates low predicted exploitation likelihood in the near term, though the broad install base of BIG-IP keeps this worth prompt patching on IPsec-enabled systems.
An authenticated attacker holding at least the resource administrator role on an F5 BIG-IP system can use the iHealth command to escape the tmsh restricted shell and obtain a full bash shell, a privilege escalation rated CVSS 4.0 8.5 (and CVSS 3.1 8.5, AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:N). The impact is most severe on BIG-IP systems running in Appliance mode, where tmsh confinement is the enforced control and successful exploitation lets the attacker cross a security boundary; on systems not in Appliance mode the bash access is correspondingly less consequential. There is no public exploit identified at time of analysis and no CISA KEV listing, and EPSS is low (0.39%, 31st percentile), making this an access-gated privilege-escalation issue rather than a mass-exploitation threat. Administered roles and the Appliance mode setting are the primary gating factors.
Undisclosed network traffic can crash the Traffic Management Microkernel (TMM) on F5 BIG-IP, the data-plane process responsible for handling all traffic on the device, resulting in a denial of service against the whole system. Exploitation requires a narrow, non-default configuration: a DTLS 1.2 virtual server with a Server SSL profile that has a certificate and key installed and the SSL Sign Hash set to ANY, plus a backend server enabled for DTLS 1.2 with client authentication; no authentication or user interaction is required against a device in that state, but other configurations are not affected. No public exploit code has been identified at time of analysis and CISA KEV does not list this issue; EPSS is low at 0.24% (14th percentile), consistent with an availability-only flaw gated by a specific configuration rather than a broadly weaponizable one.
Resource exhaustion in F5 BIG-IP and BIG-IP Next CNF DNS cache allows remote unauthenticated attackers to increase memory utilization on a DNS-caching virtual server, causing a high availability impact when malicious DNS queries are delivered. The flaw is only reachable when the non-default DNS cache feature is configured on a virtual server, and software versions past End of Technical Support were not evaluated. No public exploit was identified at time of analysis, CISA KEV status is not indicated, and EPSS is low at 0.35%.
Authenticated high-privilege users can exploit insufficient file path validation in the F5 BIG-IP Configuration utility to achieve high confidentiality and integrity impact within the management interface, though the flaw requires a network-reachable management session with elevated privileges. No public exploit code has been identified, and EPSS probability is low at 0.37% (29th percentile). The issue affects numerous BIG-IP modules as listed in the CPE, and End-of-Technical-Support versions were not evaluated, so unsupported builds cannot be assumed unaffected.
Privilege escalation in F5 BIG-IP lets an authenticated user who already holds at least the Resource Administrator role escalate to a higher privilege level by invoking an undisclosed iControl REST endpoint or TMOS Shell (tmsh) command that executes arbitrary operating-system commands, crossing a security boundary (scope changed, S:C). The flaw affects BIG-IP across essentially every licensed module (LTM, ASM, APM, AFM, Advanced WAF, Analytics, AVR, GTM, DNS, PEM, CGNAT, SSL Orchestrator, Container Ingress Services, and others) that share the underlying TMOS management plane; software versions past End of Technical Support were not evaluated by F5 and should be treated as potentially affected. Exploitation requires an authenticated session with administrative-tier access (PR:H), so the realistic attacker population is insiders or an adversary who has already compromised such an account - no public exploit code has been identified at time of analysis and EPSS is low (0.39%, 31st percentile), which is consistent with the high privilege prerequisite rather than a mass-exploitation scenario.
Stored cross-site scripting in the F5 BIG-IP Configuration utility lets an authenticated, high-privileged management user plant JavaScript that later executes in the browser session of any other administrator who loads the affected (undisclosed) page, enabling session-scoped data theft and privileged configuration actions under the victim's identity. Exploitation requires the attacker to already hold a privileged account on the management interface plus a second user to trigger the payload, and F5 hardening guidance assumes the Configuration utility is not internet-exposed. No public exploit code has been identified at time of analysis and EPSS is low at 0.28% (19th percentile), yet the vendor-assigned CVSS 4.0 base score of 8.4 (High) and the breadth of affected BIG-IP modules make this a meaningful risk for internet-reachable or weakly segmented management planes.
Unauthenticated remote attackers who can reach the BIG-IP Configuration utility (TMUI/management interface) can retrieve content from undisclosed endpoints that return static, non-sensitive information, resulting in a limited confidentiality exposure (CVSS 4.0 base 6.9; assessed CVSS 3.1 5.3, confidentiality-only, no integrity or availability impact). No public exploit code and no confirmed active exploitation were identified at time of analysis, and EPSS is low at 0.40% (33rd percentile), consistent with an information-disclosure issue whose practical risk is governed almost entirely by whether the management plane is exposed. The primary mitigation is F5's long-standing guidance to keep the Configuration utility on an isolated management network; organizations that do so have no general network reachability, making this a low-priority item despite the headline 6.9 score.
Undisclosed crafted network traffic can corrupt or modify data handled by F5 BIG-IP when the affected flow uses a protocol that lacks message integrity protection, allowing an unauthenticated remote party to alter data without any confidentiality or availability impact. The issue affects BIG-IP broadly across the LTM, ASM/Advanced WAF, APM, AFM, GTM/DNS, CGNAT, Container Ingress Services and related module lines, and carries a CVSS 4.0 base score of 6.3 (AV:N/AC:L/AT:P/PR:N/UI:N/VI:L), meaning exploitation is gated by attack prerequisites - the attacker must be able to inject traffic into a suitable integrity-less flow - rather than by authentication. Risk is moderate: EPSS is low at 0.25% (14th percentile), there is no KEV listing and no public exploit identified at time of analysis, so this is a hardening and integrity-assurance item rather than an emergency patch trigger.
Denial of service in F5 BIG-IP hardware platforms occurs when the High-Speed Bridge (HSB) locks up under specific undisclosed traffic conditions, though the trigger is non-deterministic and cannot be reliably forced by an attacker (high attack complexity). This affects BIG-IP hardware appliances containing HSB; software-only/virtual editions and End-of-Technical-Support versions are not affected. No authentication or user interaction is required, but no public exploit has been identified and EPSS score is 0.23% (low likelihood).
Denial of service in F5 BIG-IP's Traffic Management Microkernel (TMM) lets a remote, unauthenticated attacker crash the traffic-processing core by sending undisclosed crafted TCP/UDP traffic, but only on systems where the database variable tm.tcpudptxchecksum has been set to the non-default value 'Software-only'; default configurations are not affected. The root cause is a memory-corruption class defect (CWE-787, out-of-bounds write) in TMM's software checksum handling, rated 8.2 under the vendor's CVSS 4.0 vector, while independent assessment with CVSS 3.1 (AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H) places it lower because the non-default checksum setting is a hard prerequisite (captured as AT:P in the 4.0 vector). EPSS is low (0.35%, 26th percentile), no public exploit code has been identified at time of analysis, and the issue is not listed in CISA KEV. Because TMM is shared across virtually every BIG-IP module, an affected appliance loses its data-plane forwarding capability each time TMM terminates.
A directory traversal flaw in F5 BIG-IP's Traffic Management User Interface (TMUI) allows an already highly privileged, authenticated administrator of the management console to read files outside the intended directory scope on affected BIG-IP systems. The high-privilege prerequisite (PR:H in the vector) is the primary limiting factor: unauthenticated or low-privileged remote users cannot trigger the flaw, and the impact is confined to confidentiality (unauthorized file reads) with no stated integrity or availability effect. No public exploit code has been identified and there is no CISA KEV confirmation of active exploitation; EPSS sits at 1.19% (67th percentile), making this a moderate-priority hardening item rather than an emergency, though exposure rises if the TMUI management interface is internet-reachable or admin credentials are shared with lower-trust operators.
Appliance mode restrictions in F5 BIG-IP can be escaped by a highly privileged, authenticated administrator who already holds SCP and SFTP access to the device, allowing undisclosed commands to run outside the restricted shell that Appliance mode is designed to enforce. The flaw is a command-injection class issue (CWE-78) in the BIG-IP platform and affects the broad set of BIG-IP modules (APM, ASM/AWAF, AFM, Analytics, AAM, CGNAT, CIS, and others) only when the system is deliberately configured in Appliance mode - a non-default hardened lockdown state. Exploitation requires PR:H per the CVSS vector, meaning no unauthenticated or low-privileged path exists, and there is no public exploit identified at time of analysis; EPSS is low at 0.44% (37th percentile), and the CVE is not listed in CISA KEV. The net effect is a confidentiality and integrity impact (high C/I, no availability impact) for environments that tier a hardened Appliance-mode posture against trusted administrators.
Undisclosed network traffic can cause the Traffic Management Microkernel (TMM) to terminate on F5 BIG-IP devices that use the embedded Packet Velocity Acceleration (ePVA) feature on hardware containing an ePVA chip, resulting in a denial-of-service condition. This unauthenticated remote DoS (assessed CVSS 3.1 7.5, AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H) affects configurations using ePVA for virtual servers, NAT, or SNAT objects; devices without ePVA hardware or not using the feature are not exploitable. No public exploit identified at time of analysis, and the EPSS score is low (0.35%).
Remote unauthenticated attackers can cause a denial-of-service condition in F5 BIG-IP by sending undisclosed traffic to a virtual server configured with an iRule that uses the ILX::call command, resulting in termination of the Traffic Management Microkernel (TMM). This vulnerability, tracked as CVE-2025-53474, affects supported (non-EoTS) BIG-IP versions only when such a non-default iRule is present; devices without ILX::call-based iRules are not exploitable. No public exploit or active exploitation is known at time of analysis, and the EPSS score is low (0.35%, percentile 26%), though the CVSS 4.0 base score is 8.7 due to high availability impact.
A use-after-free (CWE-416) in F5 BIG-IP's Traffic Management Microkernel (TMM) allows remote unauthenticated attackers to crash the data-plane process when a TCP profile with Multipath TCP (MPTCP) explicitly enabled is applied to a virtual server. Only deployments with non-default MPTCP-enabled TCP profiles are exposed; successful triggering also depends on undisclosed traffic patterns and conditions beyond the attacker's control, so the crash cannot be forced reliably. Impact is availability-only (CVSS 4.0: 8.7, VA:H with VC:N/VI:N), no public exploit code or confirmed active exploitation is identified at time of analysis, and EPSS is low (~0.44%, 37th percentile).
Denial of service in F5 BIG-IP allows remote unauthenticated attackers to exhaust memory resources on virtual servers configured with an iRule containing the HTTP::respond command. The issue affects multiple BIG-IP modules and BIG-IP Next variants, excluding releases that have reached End of Technical Support, and successful exploitation only impacts availability with no confidentiality or integrity effect. No public exploit code has been identified at time of analysis, and EPSS estimates a low exploitation likelihood of 0.43%.

Big-Ip Access Policy Manager is affected by user interface (ui) misrepresentation of critical information (CVSS 3.1).
Denial of service in F5 BIG-IP allows remote, unauthenticated attackers to terminate the Traffic Management Microkernel (TMM) and disrupt data-plane traffic processing. The flaw is a double-free (CWE-415) triggered by undisclosed network traffic, but exploitation is gated by a hardware precondition: the BIG-IP system must run on a multi-bladed chassis platform with more than one active blade, so single-blade and standard appliance deployments are not described as affected. No public exploit code has been identified at time of analysis, KEV status is not indicated, and EPSS is low at 0.35% (27th percentile); nevertheless, a TMM crash on a production load balancer can cause an immediate traffic outage. Vendor advisory: K000156912.
Denial of service in F5 BIG-IP allows remote, unauthenticated attackers to terminate the Traffic Management Microkernel (TMM) and disrupt traffic handling, but only on systems where IPsec is configured - deployments without an IPsec configuration are not exposed. The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:N/UI:N with VC:N/VI:N/VA:H) and the corresponding CVSS 3.1 assessment agree that the effect is purely availability loss (a TMM crash), with no confidentiality or integrity impact, which makes this a high-severity (8.7) but non-compromising availability issue against appliances that are common internet-facing edge devices. No public exploit code and no confirmed active exploitation were identified at time of analysis, and the EPSS score of roughly 0.37% (29th percentile) indicates low predicted exploitation likelihood in the near term, though the broad install base of BIG-IP keeps this worth prompt patching on IPsec-enabled systems.
An authenticated attacker holding at least the resource administrator role on an F5 BIG-IP system can use the iHealth command to escape the tmsh restricted shell and obtain a full bash shell, a privilege escalation rated CVSS 4.0 8.5 (and CVSS 3.1 8.5, AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:N). The impact is most severe on BIG-IP systems running in Appliance mode, where tmsh confinement is the enforced control and successful exploitation lets the attacker cross a security boundary; on systems not in Appliance mode the bash access is correspondingly less consequential. There is no public exploit identified at time of analysis and no CISA KEV listing, and EPSS is low (0.39%, 31st percentile), making this an access-gated privilege-escalation issue rather than a mass-exploitation threat. Administered roles and the Appliance mode setting are the primary gating factors.
Undisclosed network traffic can crash the Traffic Management Microkernel (TMM) on F5 BIG-IP, the data-plane process responsible for handling all traffic on the device, resulting in a denial of service against the whole system. Exploitation requires a narrow, non-default configuration: a DTLS 1.2 virtual server with a Server SSL profile that has a certificate and key installed and the SSL Sign Hash set to ANY, plus a backend server enabled for DTLS 1.2 with client authentication; no authentication or user interaction is required against a device in that state, but other configurations are not affected. No public exploit code has been identified at time of analysis and CISA KEV does not list this issue; EPSS is low at 0.24% (14th percentile), consistent with an availability-only flaw gated by a specific configuration rather than a broadly weaponizable one.
Resource exhaustion in F5 BIG-IP and BIG-IP Next CNF DNS cache allows remote unauthenticated attackers to increase memory utilization on a DNS-caching virtual server, causing a high availability impact when malicious DNS queries are delivered. The flaw is only reachable when the non-default DNS cache feature is configured on a virtual server, and software versions past End of Technical Support were not evaluated. No public exploit was identified at time of analysis, CISA KEV status is not indicated, and EPSS is low at 0.35%.
Authenticated high-privilege users can exploit insufficient file path validation in the F5 BIG-IP Configuration utility to achieve high confidentiality and integrity impact within the management interface, though the flaw requires a network-reachable management session with elevated privileges. No public exploit code has been identified, and EPSS probability is low at 0.37% (29th percentile). The issue affects numerous BIG-IP modules as listed in the CPE, and End-of-Technical-Support versions were not evaluated, so unsupported builds cannot be assumed unaffected.
Privilege escalation in F5 BIG-IP lets an authenticated user who already holds at least the Resource Administrator role escalate to a higher privilege level by invoking an undisclosed iControl REST endpoint or TMOS Shell (tmsh) command that executes arbitrary operating-system commands, crossing a security boundary (scope changed, S:C). The flaw affects BIG-IP across essentially every licensed module (LTM, ASM, APM, AFM, Advanced WAF, Analytics, AVR, GTM, DNS, PEM, CGNAT, SSL Orchestrator, Container Ingress Services, and others) that share the underlying TMOS management plane; software versions past End of Technical Support were not evaluated by F5 and should be treated as potentially affected. Exploitation requires an authenticated session with administrative-tier access (PR:H), so the realistic attacker population is insiders or an adversary who has already compromised such an account - no public exploit code has been identified at time of analysis and EPSS is low (0.39%, 31st percentile), which is consistent with the high privilege prerequisite rather than a mass-exploitation scenario.
Stored cross-site scripting in the F5 BIG-IP Configuration utility lets an authenticated, high-privileged management user plant JavaScript that later executes in the browser session of any other administrator who loads the affected (undisclosed) page, enabling session-scoped data theft and privileged configuration actions under the victim's identity. Exploitation requires the attacker to already hold a privileged account on the management interface plus a second user to trigger the payload, and F5 hardening guidance assumes the Configuration utility is not internet-exposed. No public exploit code has been identified at time of analysis and EPSS is low at 0.28% (19th percentile), yet the vendor-assigned CVSS 4.0 base score of 8.4 (High) and the breadth of affected BIG-IP modules make this a meaningful risk for internet-reachable or weakly segmented management planes.
Unauthenticated remote attackers who can reach the BIG-IP Configuration utility (TMUI/management interface) can retrieve content from undisclosed endpoints that return static, non-sensitive information, resulting in a limited confidentiality exposure (CVSS 4.0 base 6.9; assessed CVSS 3.1 5.3, confidentiality-only, no integrity or availability impact). No public exploit code and no confirmed active exploitation were identified at time of analysis, and EPSS is low at 0.40% (33rd percentile), consistent with an information-disclosure issue whose practical risk is governed almost entirely by whether the management plane is exposed. The primary mitigation is F5's long-standing guidance to keep the Configuration utility on an isolated management network; organizations that do so have no general network reachability, making this a low-priority item despite the headline 6.9 score.
Undisclosed crafted network traffic can corrupt or modify data handled by F5 BIG-IP when the affected flow uses a protocol that lacks message integrity protection, allowing an unauthenticated remote party to alter data without any confidentiality or availability impact. The issue affects BIG-IP broadly across the LTM, ASM/Advanced WAF, APM, AFM, GTM/DNS, CGNAT, Container Ingress Services and related module lines, and carries a CVSS 4.0 base score of 6.3 (AV:N/AC:L/AT:P/PR:N/UI:N/VI:L), meaning exploitation is gated by attack prerequisites - the attacker must be able to inject traffic into a suitable integrity-less flow - rather than by authentication. Risk is moderate: EPSS is low at 0.25% (14th percentile), there is no KEV listing and no public exploit identified at time of analysis, so this is a hardening and integrity-assurance item rather than an emergency patch trigger.
Denial of service in F5 BIG-IP hardware platforms occurs when the High-Speed Bridge (HSB) locks up under specific undisclosed traffic conditions, though the trigger is non-deterministic and cannot be reliably forced by an attacker (high attack complexity). This affects BIG-IP hardware appliances containing HSB; software-only/virtual editions and End-of-Technical-Support versions are not affected. No authentication or user interaction is required, but no public exploit has been identified and EPSS score is 0.23% (low likelihood).
Denial of service in F5 BIG-IP's Traffic Management Microkernel (TMM) lets a remote, unauthenticated attacker crash the traffic-processing core by sending undisclosed crafted TCP/UDP traffic, but only on systems where the database variable tm.tcpudptxchecksum has been set to the non-default value 'Software-only'; default configurations are not affected. The root cause is a memory-corruption class defect (CWE-787, out-of-bounds write) in TMM's software checksum handling, rated 8.2 under the vendor's CVSS 4.0 vector, while independent assessment with CVSS 3.1 (AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H) places it lower because the non-default checksum setting is a hard prerequisite (captured as AT:P in the 4.0 vector). EPSS is low (0.35%, 26th percentile), no public exploit code has been identified at time of analysis, and the issue is not listed in CISA KEV. Because TMM is shared across virtually every BIG-IP module, an affected appliance loses its data-plane forwarding capability each time TMM terminates.
A directory traversal flaw in F5 BIG-IP's Traffic Management User Interface (TMUI) allows an already highly privileged, authenticated administrator of the management console to read files outside the intended directory scope on affected BIG-IP systems. The high-privilege prerequisite (PR:H in the vector) is the primary limiting factor: unauthenticated or low-privileged remote users cannot trigger the flaw, and the impact is confined to confidentiality (unauthorized file reads) with no stated integrity or availability effect. No public exploit code has been identified and there is no CISA KEV confirmation of active exploitation; EPSS sits at 1.19% (67th percentile), making this a moderate-priority hardening item rather than an emergency, though exposure rises if the TMUI management interface is internet-reachable or admin credentials are shared with lower-trust operators.
Appliance mode restrictions in F5 BIG-IP can be escaped by a highly privileged, authenticated administrator who already holds SCP and SFTP access to the device, allowing undisclosed commands to run outside the restricted shell that Appliance mode is designed to enforce. The flaw is a command-injection class issue (CWE-78) in the BIG-IP platform and affects the broad set of BIG-IP modules (APM, ASM/AWAF, AFM, Analytics, AAM, CGNAT, CIS, and others) only when the system is deliberately configured in Appliance mode - a non-default hardened lockdown state. Exploitation requires PR:H per the CVSS vector, meaning no unauthenticated or low-privileged path exists, and there is no public exploit identified at time of analysis; EPSS is low at 0.44% (37th percentile), and the CVE is not listed in CISA KEV. The net effect is a confidentiality and integrity impact (high C/I, no availability impact) for environments that tier a hardened Appliance-mode posture against trusted administrators.
Undisclosed network traffic can cause the Traffic Management Microkernel (TMM) to terminate on F5 BIG-IP devices that use the embedded Packet Velocity Acceleration (ePVA) feature on hardware containing an ePVA chip, resulting in a denial-of-service condition. This unauthenticated remote DoS (assessed CVSS 3.1 7.5, AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H) affects configurations using ePVA for virtual servers, NAT, or SNAT objects; devices without ePVA hardware or not using the feature are not exploitable. No public exploit identified at time of analysis, and the EPSS score is low (0.35%).
Remote unauthenticated attackers can cause a denial-of-service condition in F5 BIG-IP by sending undisclosed traffic to a virtual server configured with an iRule that uses the ILX::call command, resulting in termination of the Traffic Management Microkernel (TMM). This vulnerability, tracked as CVE-2025-53474, affects supported (non-EoTS) BIG-IP versions only when such a non-default iRule is present; devices without ILX::call-based iRules are not exploitable. No public exploit or active exploitation is known at time of analysis, and the EPSS score is low (0.35%, percentile 26%), though the CVSS 4.0 base score is 8.7 due to high availability impact.
A use-after-free (CWE-416) in F5 BIG-IP's Traffic Management Microkernel (TMM) allows remote unauthenticated attackers to crash the data-plane process when a TCP profile with Multipath TCP (MPTCP) explicitly enabled is applied to a virtual server. Only deployments with non-default MPTCP-enabled TCP profiles are exposed; successful triggering also depends on undisclosed traffic patterns and conditions beyond the attacker's control, so the crash cannot be forced reliably. Impact is availability-only (CVSS 4.0: 8.7, VA:H with VC:N/VI:N), no public exploit code or confirmed active exploitation is identified at time of analysis, and EPSS is low (~0.44%, 37th percentile).
Denial of service in F5 BIG-IP allows remote unauthenticated attackers to exhaust memory resources on virtual servers configured with an iRule containing the HTTP::respond command. The issue affects multiple BIG-IP modules and BIG-IP Next variants, excluding releases that have reached End of Technical Support, and successful exploitation only impacts availability with no confidentiality or integrity effect. No public exploit code has been identified at time of analysis, and EPSS estimates a low exploitation likelihood of 0.43%.
