Junos Os Evolved
Monthly
Remote denial-of-service in Juniper Networks Junos OS and Junos OS Evolved 25.2 (before 25.2R2 / 25.2R2-EVO) lets an adjacent, unauthenticated BGP peer crash the routing protocol daemon (RPD) by sending a single malformed non-inet/inet6 unicast BGP update over an already-established session. The RPD crash-and-restart produces a full routing outage until reconvergence completes, though the crash occurs before the update is readvertised so there is no downstream propagation to other routers. CVSS 4.0 base score is 7.1; there is no public exploit identified at time of analysis and it is not listed in CISA KEV.
Denial-of-service in Juniper Junos OS Evolved on PTX Series routers lets an unauthenticated network attacker crash the advanced forwarding toolkit process (evo-aftmand) on the Packet Forwarding Engine by driving continuous routing updates that produce unified-list (unilist) ECMP routes. The resulting internal state corruption generates an evo-aftmand-bx core and halts forwarding, requiring a manual FPC restart or system reboot to recover. No public exploit identified at time of analysis; the vendor (Juniper SIRT) notes successful exploitation depends on a sequence of events outside the attacker's direct control, so this is a high-CVSS availability issue rather than a trivially reproducible one.
Memory leak in Juniper Networks l2ald daemon allows adjacent attackers to crash Layer 2 services on EVPN-MPLS networks. Affects Junos OS and Junos OS Evolved across multiple versions. Unauthenticated attackers on the same network segment can trigger resource exhaustion by causing ESI route churn from multi-homed Provider Edge devices, forcing l2ald process crash and restart. No public exploit identified at time of analysis, but exploitation requires only network adjacency without authentication.
Local privilege escalation in Juniper Networks Junos OS Evolved on PTX Series routers allows authenticated users with low privileges to gain high-privileged direct access to Flexible PIC Concentrators (FPCs), enabling potential full compromise of affected line cards. Impacts PTX10004, PTX10008, PTX10016 with JNP10K-LC1201 or JNP10K-LC1202 line cards across multiple firmware branches. Missing authentication on critical FPC management functions permits unauthorized privilege elevation. No public exploit identified at time of analysis.
Management daemon deadlock in Juniper Networks Junos OS 23.4-24.4 and Junos OS Evolved enables network-based authenticated attackers to trigger complete management plane denial-of-service via rapid NETCONF session cycling. Vulnerability causes mgd processes to hang in lockf state, exhausting process pool and preventing administrative logins. Recovery requires device power-cycle. Affects deployments using NETCONF management interface with authenticated remote users. No public exploit identified at time of analysis.
Local privilege escalation in Juniper Networks Junos OS and Junos OS Evolved allows low-privileged authenticated users to execute arbitrary code with root privileges. When unsigned Python operation scripts are enabled in device configuration, attackers can inject and execute malicious op scripts under root-equivalent context, achieving complete system compromise. Affects all Junos OS versions before 22.4R3-S7 and multiple branches through 24.4, plus corresponding Junos OS Evolved releases. No public exploit identified at time of analysis. CVSS 8.5 (High) with local attack vector requiring low privileges and no user interaction.
Juniper Junos OS and Junos OS Evolved contain a use-after-free vulnerability in the 802.1X authentication daemon that allows authenticated, network-adjacent attackers to crash the process or achieve arbitrary code execution as root by triggering specific port state changes. Exploitation requires precise timing of a change-of-authorization event during port transitions, making reliable exploitation difficult but possible. Systems with 802.1X port-based network access control enabled are affected, and no patch is currently available.
Memory exhaustion in Juniper Networks Junos OS and Junos OS Evolved snmpd allows an authenticated network attacker to crash SNMP monitoring by sending specific valid SNMPv3 queries that trigger an out-of-bounds write and progressive memory leak. The snmpd process will exhaust available memory over time, crash, and restart, rendering SNMP-based network monitoring unavailable for the duration of each crash cycle. No public exploit code has been identified at time of analysis, and this is not listed in CISA KEV; however, the CVSS 4.0 supplemental metric AU:Y indicates the attack is automatable.
NULL pointer dereference in the Juniper Networks Junos OS and Junos OS Evolved management daemon (mgd) allows a local, high-privileged attacker to crash the mgd process by manipulating a specific 'system services ssh' configuration parameter. Repeated execution of the offending configuration commands sustains the Denial of Service condition until the action ceases, as mgd will restart but crash again upon re-triggering. No public exploit code has been identified and this vulnerability is not listed in the CISA Known Exploited Vulnerabilities catalog; the attack barrier is high, requiring both local access and administrative-level credentials.
Traffic forwarding on Juniper QFX Series switches running Junos OS Evolved can be fully disrupted by an adjacent, unauthenticated attacker exploiting a race condition in the sFlow collector handler. When sFlow collector reachability changes trigger a next-hop entry update concurrently with the sFlow thread reading that same next-hop data, the evo-pfemand process crashes and all packet forwarding halts until the process automatically restarts. No public exploit code exists and this vulnerability is not listed in the CISA KEV catalog at time of analysis, but the availability impact is severe for any network segment relying on the affected switch.
License exhaustion in Juniper Networks Junos OS Evolved lets an unauthenticated, network-based attacker reach the device's license-management process, which was intended to be internal-only but is exposed on an open network port due to incorrect initialization. All Junos OS Evolved releases before 23.2R2-EVO are affected. There is no public exploit identified at time of analysis and it is not listed in CISA KEV, but the low attack complexity and lack of authentication make it a credible network-facing denial-of-service risk to affected routing/switching platforms.
Denial-of-service in Juniper Networks Junos OS and Junos OS Evolved on EX Series, QFX Series, and MX Series allows a local, low-privileged attacker to crash the l2ald (Layer 2 Address Learning Daemon) by issuing a specific 'show l2-learning' CLI command, disrupting all Layer 2 services until the process automatically restarts. The root cause is a Return of Pointer Value Outside of Expected Range flaw (CWE-466) in the fileio library. No public exploit has been identified at time of analysis, and active exploitation has not been confirmed by CISA or the vendor.
Junos OS Evolved exposes an internal communication process to the network via an unintended open port due to incorrect initialization, enabling unauthenticated remote attackers to interact with a service never designed for external access. Affected Juniper devices suffer limited information disclosure and elevated CPU consumption as the misbound process handles unsolicited ingress packets - a soft availability degradation rather than a crash. No public exploit has been identified at time of analysis and the vulnerability is not listed in CISA KEV, but the unauthenticated network vector across a broad version range warrants prompt patching on internet-facing routing infrastructure.
Unauthenticated buffer overflow in Juniper Networks Junos OS Evolved advanced forwarding toolkit (evo-aftmand/evo-pfemand) permits adjacent attackers to crash PTX Series and QFX5000 Series devices via crafted multicast packets. Exploitation triggers line card or device restart, sustaining denial of service under continuous attack. Affects multiple Junos OS Evolved release branches before patched versions. No public exploit identified at time of analysis. Attack requires adjacent network access but no authentication, making exploitation feasible in shared network segments.
Repeated telemetry collector subscriptions in Juniper Junos OS and Junos OS Evolved trigger a use-after-free vulnerability in the chassis daemon, allowing authenticated network attackers to crash critical processes and cause denial of service. Affected versions prior to 22.4R3-S8, 23.2R2-S5, and 23.4R2 are vulnerable when telemetry-capable daemons experience continuous sensor subscription cycles. No patch is currently available, leaving affected systems exposed until updates are released.
MAC learning failures in Juniper Junos OS Evolved's Layer 2 Control Protocol Daemon can be triggered by a network-adjacent attacker who repeatedly toggles the management interface, causing label-switched interface MAC address learning to halt while generating excessive logs and consuming high CPU resources. This calculation error (CWE-682) affects availability through denial of service and currently has no available patch. The attack requires network adjacency but no authentication or user interaction.
Denial of service in Juniper Junos OS and Junos OS Evolved allows an adjacent IS-IS neighbor to trigger a memory leak in the routing protocol daemon by sending specially crafted update packets. Repeated exploitation exhausts available memory and crashes the rpd process, rendering routing unavailable. No patch is currently available.

An Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') vulnerability in the CLI of Juniper Networks Junos OS and Junos OS Evolved allows a high privileged, local attacker to escalated their privileges to root. When a user provides specifically crafted arguments to the 'request system logout' command, these will be executed as root on the shell, which can completely compromise the device. This issue affects: Junos OS: * all versions before 21.2R3-S9, * 21.4 versions before 21.4R3-S8, * 22.2 versions before 22.2R3-S6, * 22.3 versions before 22.3R3-S3, * 22.4 versions before 22.4R3-S6, * 23.2 versions before 23.2R2-S1, * 23.4 versions before 23.4R1-S2, 23.4R2; Junos OS Evolved: * all versions before 22.4R3-S6-EVO, * 23.2-EVO versions before 23.2R2-S1-EVO, * 23.4-EVO versions before 23.4R1-S2-EVO, 23.4R2-EVO.
A Missing Release of Memory after Effective Lifetime vulnerability in the routing protocol daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows a local, low privileged user to cause an impact to the availability of the device. When RIB sharding is enabled and a user executes one of several routing related 'show' commands, a certain amount of memory is leaked. When all available memory has been consumed rpd will crash and restart. The leak can be monitored with the CLI command: show task memory detail | match task_shard_mgmt_cookie where the allocated memory in bytes can be seen to continuously increase with each exploitation. This issue affects: Junos OS: * all versions before 21.2R3-S9, * 21.4 versions before 21.4R3-S11, * 22.2 versions before 22.2R3-S7, * 22.4 versions before 22.4R3-S7, * 23.2 versions before 23.2R2-S4, * 23.4 versions before 23.4R2-S4, * 24.2 versions before 24.2R2, * 24.4 versions before 24.4R1-S2, 24.4R2; Junos OS Evolved: * all versions before 22.2R3-S7-EVO * 22.4-EVO versions before 22.4R3-S7-EVO, * 23.2-EVO versions before 23.2R2-S4-EVO, * 23.4-EVO versions before 23.4R2-S4-EVO, * 24.2-EVO versions before 24.2R2-EVO, * 24.4-EVO versions before 24.4R2-EVO.
CVE-2025-52985 is a security vulnerability (CVSS 5.3). Remediation should follow standard vulnerability management procedures.
A NULL Pointer Dereference vulnerability in the routing protocol daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated, network-based attacker to cause impact to the availability of the device. When static route points to a reject next hop and a gNMI query is processed for that static route, rpd crashes and restarts. This issue affects: Junos OS: * all versions before 21.2R3-S9, * 21.4 versions before 21.4R3-S10, * 22.2 versions before 22.2R3-S6, * 22.4 versions before 22.4R3-S6, * 23.2 versions before 23.2R2-S3, * 23.4 versions before 23.4R2-S4, * 24.2 versions before 24.2R1-S2, 24.2R2; Junos OS Evolved: * all versions before 22.4R3-S7-EVO, * 23.2-EVO versions before 23.2R2-S3-EVO, * 23.4-EVO versions before 23.4R2-S4-EVO, * 24.2-EVO versions before 24.2R2-EVO.
A Reachable Assertion vulnerability in the Routing Protocol Daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated, network-based attacker to cause a Denial of Service (DoS). When the device receives a specific BGP UPDATE packet, the rpd crashes and restarts. Continuous receipt of this specific packet will cause a sustained DoS condition. For the issue to occur, BGP multipath with "pause-computation-during-churn" must be configured on the device, and the attacker must send the paths via a BGP UPDATE from a established BGP peer. This issue affects: Junos OS: * All versions before 21.4R3-S7, * from 22.3 before 22.3R3-S3, * from 22.4 before 22.4R3-S5, * from 23.2 before 23.2R2, * from 23.4 before 23.4R2. Junos OS Evolved: * All versions before 21.4R3-S7-EVO, * from 22.3 before 22.3R3-S3-EVO, * from 22.4 before 22.4R3-S5-EVO, * from 23.2 before 23.2R2-EVO, * from 23.4 before 23.4R2-EVO.
A Reachable Assertion vulnerability in the routing protocol daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows an adjacent, unauthenticated attacker to cause a Denial of Service (DoS).On all Junos OS and Junos OS Evolved devices, when route validation is enabled, a rare condition during BGP initial session establishment can lead to an rpd crash and restart. This occurs specifically when the connection request fails during error-handling scenario. Continued session establishment failures leads to a sustained DoS condition.

Remote denial-of-service in Juniper Networks Junos OS and Junos OS Evolved 25.2 (before 25.2R2 / 25.2R2-EVO) lets an adjacent, unauthenticated BGP peer crash the routing protocol daemon (RPD) by sending a single malformed non-inet/inet6 unicast BGP update over an already-established session. The RPD crash-and-restart produces a full routing outage until reconvergence completes, though the crash occurs before the update is readvertised so there is no downstream propagation to other routers. CVSS 4.0 base score is 7.1; there is no public exploit identified at time of analysis and it is not listed in CISA KEV.
Denial-of-service in Juniper Junos OS Evolved on PTX Series routers lets an unauthenticated network attacker crash the advanced forwarding toolkit process (evo-aftmand) on the Packet Forwarding Engine by driving continuous routing updates that produce unified-list (unilist) ECMP routes. The resulting internal state corruption generates an evo-aftmand-bx core and halts forwarding, requiring a manual FPC restart or system reboot to recover. No public exploit identified at time of analysis; the vendor (Juniper SIRT) notes successful exploitation depends on a sequence of events outside the attacker's direct control, so this is a high-CVSS availability issue rather than a trivially reproducible one.
Memory leak in Juniper Networks l2ald daemon allows adjacent attackers to crash Layer 2 services on EVPN-MPLS networks. Affects Junos OS and Junos OS Evolved across multiple versions. Unauthenticated attackers on the same network segment can trigger resource exhaustion by causing ESI route churn from multi-homed Provider Edge devices, forcing l2ald process crash and restart. No public exploit identified at time of analysis, but exploitation requires only network adjacency without authentication.
Local privilege escalation in Juniper Networks Junos OS Evolved on PTX Series routers allows authenticated users with low privileges to gain high-privileged direct access to Flexible PIC Concentrators (FPCs), enabling potential full compromise of affected line cards. Impacts PTX10004, PTX10008, PTX10016 with JNP10K-LC1201 or JNP10K-LC1202 line cards across multiple firmware branches. Missing authentication on critical FPC management functions permits unauthorized privilege elevation. No public exploit identified at time of analysis.
Management daemon deadlock in Juniper Networks Junos OS 23.4-24.4 and Junos OS Evolved enables network-based authenticated attackers to trigger complete management plane denial-of-service via rapid NETCONF session cycling. Vulnerability causes mgd processes to hang in lockf state, exhausting process pool and preventing administrative logins. Recovery requires device power-cycle. Affects deployments using NETCONF management interface with authenticated remote users. No public exploit identified at time of analysis.
Local privilege escalation in Juniper Networks Junos OS and Junos OS Evolved allows low-privileged authenticated users to execute arbitrary code with root privileges. When unsigned Python operation scripts are enabled in device configuration, attackers can inject and execute malicious op scripts under root-equivalent context, achieving complete system compromise. Affects all Junos OS versions before 22.4R3-S7 and multiple branches through 24.4, plus corresponding Junos OS Evolved releases. No public exploit identified at time of analysis. CVSS 8.5 (High) with local attack vector requiring low privileges and no user interaction.
Juniper Junos OS and Junos OS Evolved contain a use-after-free vulnerability in the 802.1X authentication daemon that allows authenticated, network-adjacent attackers to crash the process or achieve arbitrary code execution as root by triggering specific port state changes. Exploitation requires precise timing of a change-of-authorization event during port transitions, making reliable exploitation difficult but possible. Systems with 802.1X port-based network access control enabled are affected, and no patch is currently available.
Memory exhaustion in Juniper Networks Junos OS and Junos OS Evolved snmpd allows an authenticated network attacker to crash SNMP monitoring by sending specific valid SNMPv3 queries that trigger an out-of-bounds write and progressive memory leak. The snmpd process will exhaust available memory over time, crash, and restart, rendering SNMP-based network monitoring unavailable for the duration of each crash cycle. No public exploit code has been identified at time of analysis, and this is not listed in CISA KEV; however, the CVSS 4.0 supplemental metric AU:Y indicates the attack is automatable.
NULL pointer dereference in the Juniper Networks Junos OS and Junos OS Evolved management daemon (mgd) allows a local, high-privileged attacker to crash the mgd process by manipulating a specific 'system services ssh' configuration parameter. Repeated execution of the offending configuration commands sustains the Denial of Service condition until the action ceases, as mgd will restart but crash again upon re-triggering. No public exploit code has been identified and this vulnerability is not listed in the CISA Known Exploited Vulnerabilities catalog; the attack barrier is high, requiring both local access and administrative-level credentials.
Traffic forwarding on Juniper QFX Series switches running Junos OS Evolved can be fully disrupted by an adjacent, unauthenticated attacker exploiting a race condition in the sFlow collector handler. When sFlow collector reachability changes trigger a next-hop entry update concurrently with the sFlow thread reading that same next-hop data, the evo-pfemand process crashes and all packet forwarding halts until the process automatically restarts. No public exploit code exists and this vulnerability is not listed in the CISA KEV catalog at time of analysis, but the availability impact is severe for any network segment relying on the affected switch.
License exhaustion in Juniper Networks Junos OS Evolved lets an unauthenticated, network-based attacker reach the device's license-management process, which was intended to be internal-only but is exposed on an open network port due to incorrect initialization. All Junos OS Evolved releases before 23.2R2-EVO are affected. There is no public exploit identified at time of analysis and it is not listed in CISA KEV, but the low attack complexity and lack of authentication make it a credible network-facing denial-of-service risk to affected routing/switching platforms.
Denial-of-service in Juniper Networks Junos OS and Junos OS Evolved on EX Series, QFX Series, and MX Series allows a local, low-privileged attacker to crash the l2ald (Layer 2 Address Learning Daemon) by issuing a specific 'show l2-learning' CLI command, disrupting all Layer 2 services until the process automatically restarts. The root cause is a Return of Pointer Value Outside of Expected Range flaw (CWE-466) in the fileio library. No public exploit has been identified at time of analysis, and active exploitation has not been confirmed by CISA or the vendor.
Junos OS Evolved exposes an internal communication process to the network via an unintended open port due to incorrect initialization, enabling unauthenticated remote attackers to interact with a service never designed for external access. Affected Juniper devices suffer limited information disclosure and elevated CPU consumption as the misbound process handles unsolicited ingress packets - a soft availability degradation rather than a crash. No public exploit has been identified at time of analysis and the vulnerability is not listed in CISA KEV, but the unauthenticated network vector across a broad version range warrants prompt patching on internet-facing routing infrastructure.
Unauthenticated buffer overflow in Juniper Networks Junos OS Evolved advanced forwarding toolkit (evo-aftmand/evo-pfemand) permits adjacent attackers to crash PTX Series and QFX5000 Series devices via crafted multicast packets. Exploitation triggers line card or device restart, sustaining denial of service under continuous attack. Affects multiple Junos OS Evolved release branches before patched versions. No public exploit identified at time of analysis. Attack requires adjacent network access but no authentication, making exploitation feasible in shared network segments.
Repeated telemetry collector subscriptions in Juniper Junos OS and Junos OS Evolved trigger a use-after-free vulnerability in the chassis daemon, allowing authenticated network attackers to crash critical processes and cause denial of service. Affected versions prior to 22.4R3-S8, 23.2R2-S5, and 23.4R2 are vulnerable when telemetry-capable daemons experience continuous sensor subscription cycles. No patch is currently available, leaving affected systems exposed until updates are released.
MAC learning failures in Juniper Junos OS Evolved's Layer 2 Control Protocol Daemon can be triggered by a network-adjacent attacker who repeatedly toggles the management interface, causing label-switched interface MAC address learning to halt while generating excessive logs and consuming high CPU resources. This calculation error (CWE-682) affects availability through denial of service and currently has no available patch. The attack requires network adjacency but no authentication or user interaction.
Denial of service in Juniper Junos OS and Junos OS Evolved allows an adjacent IS-IS neighbor to trigger a memory leak in the routing protocol daemon by sending specially crafted update packets.
