CVE-2025-1547: CWE-121 in WatchGuard Fireware OS
A stack-based buffer overflow vulnerability [CWE-121] in WatchGuard Fireware OS's certificate request command could allow an authenticated privileged user to execute arbitrary code via specially crafted CLI commands.
AI Analysis
Technical Summary
This vulnerability (CWE-121) in WatchGuard Fireware OS arises from a stack-based buffer overflow in the certificate request command interface. An authenticated user with high privileges can exploit this flaw by crafting malicious CLI commands to execute arbitrary code on the affected system. The CVSS 4.0 base score is 7.5, reflecting high severity with network attack vector, high attack complexity, and requiring privileged authentication. The vulnerability affects Fireware OS versions 12.0 and 12.6 as explicitly stated.
Potential Impact
Successful exploitation could lead to arbitrary code execution by an authenticated privileged user, potentially compromising the affected device's integrity and control. This could allow an attacker to execute unauthorized commands or disrupt normal device operations.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since no patch or workaround information is provided, users should monitor WatchGuard's official advisories for updates. Until a fix is available, restrict privileged CLI access to trusted administrators only.
