Technical Summary
This vulnerability (CWE-22) in WatchGuard Fireware OS allows a privileged authenticated user to perform path traversal attacks via the Management Web UI, enabling arbitrary file write on the Firebox filesystem. The affected versions include 11.0 up to 11.12.4_Update1, 12.0 up to 12.12, and 2025.1 up to 2026.2. The CVSS 4.0 vector indicates network attack vector, low attack complexity, no user interaction, and high impact on confidentiality, integrity, and availability. No vendor advisory or patch information is currently available.
Potential Impact
An attacker with privileged authenticated access can write arbitrary files to the Firebox filesystem, potentially leading to unauthorized modification or persistence on the device. This could compromise the integrity and availability of the system. The vulnerability does not require user interaction and can be exploited remotely over the network.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict privileged access to the Management Web UI to trusted administrators only and monitor for suspicious activity related to file writes on the device.
