Improper Neutralization of Input During Web Page Generation (XSS or 'Cross-site Scripting') vulnerability in WatchGuard Fireware OS (Tigerpaw Technology Integration module) allows Stored XSS.This issue affects Fireware OS 12.4 up to and including 12.11.4, 12.5 up to and including 12.5.13, and 2025.1 up to and including 2025.1.2.
AnalysisAI
Stored Cross-Site Scripting in WatchGuard Fireware OS via the Tigerpaw Technology Integration module permits a high-privileged attacker to inject persistent malicious scripts into the web management interface. Affected versions span Fireware OS 12.4 through 12.11.4, 12.5 through 12.5.13, and 2025.1 through 2025.1.2. With user interaction, the injected payload executes in victim administrators' browsers, potentially enabling session hijacking or unauthorized configuration changes within the management plane.
Technical ContextAI
WatchGuard Fireware OS is the operating system powering WatchGuard network security appliances. The vulnerable component is the Tigerpaw Technology Integration module, a third-party integration layer within the Fireware web UI. CWE-79 (Improper Neutralization of Input During Web Page Generation) indicates the root cause: user-supplied input is stored without adequate sanitization and later rendered in HTML context without proper encoding, enabling persistent script injection. CPE cpe:2.3:o:watchguard:fireware covers all three affected release branches (12.4.x, 12.5.x, 2025.1.x). The CVSS 4.0 vector confirms network delivery (AV:N), low attack complexity (AC:L), high privilege requirement (PR:H), and passive user interaction (UI:P), consistent with a stored XSS pattern requiring an authenticated admin to both submit and later trigger the payload.
RemediationAI
The primary remediation is to apply the vendor-supplied patch per WatchGuard Security Advisory WGSA-2025-00021, available at https://www.watchguard.com/wgrd-psirt/advisory/wgsa-2025-00021. Exact fixed versions are not independently confirmed from the available input data beyond what is stated in the advisory; administrators should consult the advisory directly to identify the target upgrade versions for their release branch (12.4.x, 12.5.x, or 2025.1.x). As a compensating control prior to patching, organizations should restrict access to the Fireware web management interface to trusted administrative networks only, reducing the attack surface by limiting who can submit or interact with Tigerpaw integration data. Disabling the Tigerpaw Technology Integration module entirely, if not operationally required, would eliminate the vulnerable code path without impacting core Fireware functionality; the trade-off is loss of Tigerpaw third-party integration capabilities.
