Watchguard

Stored XSS in WatchGuard Dimension's Trusted CA certificate configuration enables an authenticated administrator to inject persistent JavaScript that executes in the browser of other authenticated administrators. The attack requires high-privilege access to the management console to plant the payload and passive interaction from a victim administrator to trigger it, constraining the threat to insider abuse or compromised admin accounts. No public exploit code or active exploitation has been identified at time of analysis; the CVSS 4.0 score of 4.8 reflects the limited, intra-admin scope.

Server-side request forgery in WatchGuard Dimension's Email Server Test configuration feature enables authenticated privileged attackers to probe and enumerate network services on adjacent network segments. The vulnerability stems from insufficient validation of server-initiated outbound requests, allowing the Dimension management platform to be weaponized as a network scanning proxy. No public exploit code has been identified at time of analysis, and the attack requires high-privilege credentials, materially limiting realistic exposure.

Stored cross-site scripting in WatchGuard Dimension's Backup Historical Data feature permits an authenticated administrator to inject arbitrary JavaScript that executes in the browser context of other users who view the affected data. The CVSS 4.0 vector (PR:H, SC:L/SI:L) confirms the attacker must hold admin credentials and that impact is confined to subsequent systems - other users' browser sessions - with no direct impact on the Dimension host itself. No public exploit code and no CISA KEV listing exist at time of analysis.

Authenticated SQL injection in WatchGuard Dimension's scheduled report feature permits arbitrary OS command execution as the Dimension WebUI process user. All versions of the product are listed as potentially affected per CPE data, with exploitation requiring a valid session holding report administration permissions. No public exploit code or CISA KEV listing has been identified at time of analysis, though the post-authentication command execution capability represents a critical risk for any deployment where report admin credentials can be obtained.

WatchGuard Dimension exposes a server-side configuration endpoint that fails to enforce the client-side lock/unlock workflow state, allowing any authenticated read-write administrator to submit configuration changes directly to the API without completing the UI unlock step. This creates a race condition where a privileged user can silently overwrite changes being made by a second concurrent administrator session. No public exploit exists and exploitation requires valid administrator credentials, but the flaw undermines the integrity of multi-administrator change management workflows in Dimension deployments.

Reflected XSS in WatchGuard Dimension's report detail page allows arbitrary JavaScript execution in the browser of an authenticated victim when they follow a specially crafted URL. The vulnerability requires social engineering an already-authenticated Dimension user - likely an administrator, given the CVSS 4.0 PR:H rating - into clicking an attacker-controlled link, constraining the attack to targeted phishing scenarios against active sessions. No public exploit code has been identified at time of analysis, and this CVE does not appear in the CISA KEV catalog. EPSS data was not provided in the source intelligence.

WatchGuard Dimension's log viewer feature exposes an SQL injection flaw that escalates directly to arbitrary command execution on the host system. An authenticated user holding report administration permissions can send specially crafted requests to the log viewer endpoint, injecting SQL that ultimately invokes OS-level commands running as the Dimension WebUI process account. No public exploit or CISA KEV listing has been identified at time of analysis, but the vulnerability class is well-understood and the vendor itself reported it, indicating confirmed existence.

Server-side request forgery in WatchGuard Dimension's Remote Backup Connection Test configuration feature allows authenticated privileged users to enumerate exposed network services on adjacent systems. The CVSS 4.0 score of 5.3 reflects confined impact - no direct compromise of the Dimension host itself, but meaningful secondary-system reconnaissance capability. No public exploit code and no CISA KEV listing have been identified at time of analysis.

WatchGuard Dimension's web login endpoint permits unlimited automated password guessing against user accounts because rate-limiting and account lockout are both absent in the default product configuration. All versions of Dimension (CPE wildcard, no version boundary) are affected in default-configured deployments. An unauthenticated remote attacker can systematically guess credentials and gain unauthorized account access; the CWE-203 classification further indicates the endpoint may expose observable discrepancies that enable username enumeration, reducing the effort required for targeted credential attacks. No public exploit has been identified at time of analysis and no CISA KEV listing exists.

Stored XSS in WatchGuard Dimension's task scheduling feature allows a low-privileged authenticated administrator to inject persistent JavaScript into scheduling fields, which silently executes in the browser session of any other user who subsequently views the affected interface. Unlike reflected XSS, the stored nature of this vulnerability means a single injection can compromise multiple sessions without further attacker interaction, including those of higher-privileged administrators. No public exploit code or active exploitation has been identified at the time of analysis.

WatchGuard Dimension's Web UI administrator passphrase change endpoint lacks CSRF protection, enabling full account takeover of global administrator accounts through a forged cross-origin browser request. An attacker who can deliver a malicious link or page to an actively authenticated global administrator can silently replace that administrator's passphrase with an attacker-controlled value, granting unrestricted access to the Dimension management platform. No public exploit code has been identified and active exploitation has not been confirmed in CISA KEV at time of analysis.

Server-side request forgery in WatchGuard Dimension's FTP Server Test configuration feature allows a privileged authenticated attacker to probe and enumerate network services on adjacent network systems. The vulnerability affects all tracked versions of WatchGuard Dimension (CPE wildcard) and is limited to subsequent-system confidentiality impact - specifically service discovery on internal or adjacent hosts. No public exploit code exists and this vulnerability is not listed in the CISA KEV catalog, indicating no confirmed active exploitation at time of analysis.

Privilege escalation to account takeover in WatchGuard Dimension allows a low-privileged Dimension Administrator to hijack a Super Administrator account by harvesting that user's session token from a diagnostic log in the web UI. Because session identifiers are written unredacted, any authenticated administrator who can read the diagnostic log can impersonate a Super Administrator while that user is logged in, gaining full control of the management platform. No public exploit identified at time of analysis, and the flaw is not listed in CISA KEV.

WatchGuard Dimension, the network security visibility and management platform, contains a business logic flaw (CWE-284) that permits an authenticated administrator to trigger multiple backend operations within a single logical request flow by sending a specially crafted HTTP request. All versions of Dimension are listed as affected via the wildcard CPE, and the impact is high confidentiality exposure on the Dimension system itself with limited subsequent-system effect. No public exploit code has been identified at time of analysis, and no CISA KEV listing exists, but the PR:H requirement constrains exploitation to actors who already hold or have compromised administrator credentials.

Blind server-side request forgery in WatchGuard Dimension's Database Server Test configuration feature allows an authenticated privileged attacker to enumerate network services on adjacent systems by exploiting observable timing or response discrepancies (CWE-208). The scope of impact extends beyond the Dimension host itself to adjacent network segments, enabling internal network reconnaissance without direct access to those systems. No public exploit is identified at time of analysis, and the high privilege requirement substantially limits the realistic attacker pool.

WatchGuard Dimension's log listening service can be rendered unavailable by an unauthenticated remote attacker flooding it with TCP SYN packets, a classic resource exhaustion denial-of-service technique. The CVSS 4.0 base score of 8.7 reflects high availability impact with no authentication, no user interaction, and no configuration prerequisite required. No public exploit code has been identified and this CVE does not appear in the CISA KEV catalog at time of analysis.

Authenticated SQL injection in WatchGuard Dimension's audit report feature enables privilege escalation to arbitrary OS command execution, running as the Dimension WebUI process account. The vulnerability is exploitable by any user holding report administration permissions, making it a significant lateral-movement and post-compromise pivot risk within WatchGuard-managed network environments. No public exploit code or CISA KEV listing has been identified at time of analysis, though the chained SQL injection-to-command-execution primitive is high impact for attackers who have obtained admin-level credentials.

Remote code execution in WatchGuard Fireware OS affects the iked IKE/IPsec VPN daemon, where a memory-safety defect lets a remote unauthenticated attacker run arbitrary code by sending specially crafted network traffic to the appliance's VPN listener. The CVSS 4.0 base score of 9.3 reflects network-reachable, no-privilege, no-interaction exploitation with high confidentiality, integrity, and availability impact. No public exploit is identified at time of analysis and it is not listed in CISA KEV, but the pre-authentication RCE profile on an internet-facing firewall makes this high priority.

Remote unauthenticated denial-of-service in WatchGuard Fireware OS targets the iked process, which handles IKE-based VPN session negotiation. By sending specially crafted network packets to the IKE service, an attacker can trigger an integer underflow in iked, crashing VPN processing and disrupting all VPN-dependent connectivity without any authentication. No public exploit code has been identified at time of analysis, and this vulnerability is not currently listed in the CISA KEV catalog.

Out-of-bounds read in the WatchGuard Fireware OS iked (Internet Key Exchange daemon) process enables remote unauthenticated attackers to crash VPN processing by sending specially crafted network traffic, resulting in a Denial of Service condition. All Fireware OS versions appear affected per the wildcard CPE, and the vulnerability is reachable without authentication from any network path to the iked listener. No public exploit code or CISA KEV listing has been identified at time of analysis, but the low attack complexity makes this a realistic target for disrupting VPN availability on WatchGuard appliances.

Integer underflow in WatchGuard Fireware OS iked (IKE daemon) process enables remote unauthenticated attackers to crash VPN processing by sending specially crafted network traffic. The flaw (CWE-191) resides in the IKEv1/IKEv2 key exchange handler, meaning any internet-exposed WatchGuard appliance with VPN enabled is reachable from the network perimeter without credentials. No public exploit code or CISA KEV listing has been identified at time of analysis, but the unauthenticated network attack vector and availability impact of 8.7 (CVSS 4.0) make this a meaningful risk for organizations relying on WatchGuard VPN for remote access continuity.

Stack-based buffer overflow in the iked (IKE daemon) process of WatchGuard Fireware OS allows a remote unauthenticated attacker to crash VPN processing via specially crafted network traffic, causing a denial-of-service condition on affected Firebox appliances. Any Firebox with IPsec VPN exposed to untrusted networks is at risk across an unspecified range of Fireware OS versions. No public exploit code has been identified at time of analysis, but the CVSS 4.0 score of 8.7 with network-accessible, zero-authentication exploitation reflects meaningful operational urgency for perimeter security devices.

Remote code execution in WatchGuard Fireware OS affects the epm (Endpoint Protection Manager) service tied to the deprecated Mobile Security feature, where a stack-based buffer overflow lets an unauthenticated remote attacker run arbitrary code on the appliance. The CVSS 4.0 base score is 9.3 (critical) with a network, no-privilege, no-interaction vector. No public exploit identified at time of analysis and it is not listed in CISA KEV, but as a perimeter firewall RCE the impact is severe for any deployment still running Mobile Security.

Remote code execution in WatchGuard Fireware OS is possible via a heap overflow (CWE-122) in the iked (IKE/IPsec key management) process, letting a remote unauthenticated attacker run arbitrary code by sending specially crafted network traffic to an affected Firebox firewall. The vendor-assigned CVSS 4.0 base score is 9.3 (critical), reflecting network-reachable, no-privilege, no-interaction exploitation with full confidentiality, integrity, and availability impact. There is no public exploit identified at time of analysis and the CVE is not in CISA KEV, but the pre-authentication nature and the perimeter role of the affected device make this a high-priority patching item.

Remote unauthenticated attackers can crash the VPN processing service on WatchGuard Fireware OS by sending specially crafted IKE network traffic that triggers a double-free memory corruption in the iked daemon. The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:N/UI:N/VA:H) confirms zero prerequisites for exploitation against any internet-exposed WatchGuard appliance with IPsec VPN active. No public exploit code has been identified at time of analysis, and the vulnerability does not appear in the CISA KEV catalog.

Out-of-bounds read in the WatchGuard Fireware OS iked (IKE daemon) process allows remote unauthenticated attackers to disrupt VPN operations by sending specially crafted network packets. The flaw resides in VPN processing logic and can crash or destabilize the IKE service, cutting off IPsec/IKEv2 tunnels for connected clients and sites. No public exploit has been identified at time of analysis and CISA KEV listing is not confirmed; however, the unauthenticated network attack vector and CVSS 4.0 score of 8.7 place this in the priority triage tier for organizations relying on WatchGuard Firebox VPN connectivity.

Remote code execution in WatchGuard Fireware OS affects the iked (IKE/IPsec VPN key-exchange) daemon, where a stack-based buffer overflow lets a remote, unauthenticated attacker run arbitrary code by sending specially crafted network traffic. Because iked terminates VPN negotiations at the network edge, any Firebox appliance exposing IKE/IPsec is reachable pre-authentication. No public exploit has been identified at time of analysis and the CVE is not listed in CISA KEV, but the pre-auth RCE profile on a perimeter security device makes this a top-priority patch.

Buffer overflow in the WatchGuard Fireware OS Management Web UI allows an authenticated administrator with network access to trigger a denial-of-service condition or potentially execute arbitrary code by submitting specially crafted traffic to the management interface. The root cause is CWE-787 (out-of-bounds write) in the web-based management component, and the CVSS 4.0 vector confirms network reachability with high-privilege authentication as prerequisites. No public exploit code or active exploitation has been identified at time of analysis, though the RCE potential on a network perimeter device elevates the severity beyond what the privilege requirement alone might suggest.

Remote code execution in the WatchGuard Agent allows an unauthenticated attacker with network access to trigger arbitrary code execution at elevated privilege due to an improper authentication flaw (CWE-306). The CVSS 4.0 base score of 9.3 reflects a network-reachable, no-interaction, no-privilege attack yielding full confidentiality, integrity, and availability impact on the affected host. No public exploit identified at time of analysis, and the flaw is not listed in CISA KEV, but the combination of pre-auth reachability and privileged code execution makes this a high-priority exposure.

Remote code execution in WatchGuard Agent lets an unauthenticated attacker positioned on an adjacent network chain a missing-authentication weakness (CWE-306) with path traversal into arbitrary code execution on the host. Rated CVSS 4.0 9.4 (Critical) by WatchGuard, the flaw combines an authentication bypass with directory traversal so no credentials or user interaction are required. No public exploit identified at time of analysis and it is not listed in CISA KEV, but the network-adjacent, no-auth, high-impact profile makes it a high-priority patch item.

Authenticated command execution in WatchGuard Fireware OS lets a privileged administrator escalate a specially crafted CLI command into arbitrary code execution via an out-of-bounds write (CWE-787). The flaw affects a very broad version span (Fireware OS 11.0 through 11.12.4_Update1, 12.0 through 12.12, and 2025.1 through 2026.2), placing most currently and historically deployed WatchGuard Firebox appliances in scope.
