AI-suggested
Since exploitation requires authenticated administrator access, limiting administrative access to trusted personnel and secure networks can reduce risk. Monitor vendor advisories for updates and apply patches promptly once available.
Description
A stored cross-site scripting (XSS) vulnerability exists in WatchGuard Fireware OS within the spamBlocker module. This vulnerability requires an authenticated administrator session on a locally managed Firebox device. It affects Fireware OS versions from 12.0 through 12.5.12+701324 and from 12.6 through 12.11. The vulnerability allows an attacker with administrative privileges to inject malicious scripts that could be executed in the context of the administrator's browser session.
