WatchGuard just dropped a security advisory (July 2) warning that its Firebox firewall needs urgent patching for 17 vulnerabilities. The headline risk is clear: at least one major issue can lead to remote code execution (RCE), and the list also includes denial-of-service (DoS) and arbitrary file write problems—exactly the kind of “big attack surface, broad blast radius” fixes you don’t want to delay. The most critical item is CVE-2026-13368 (CVSS v4: 9.2). It stems from a race condition in Fireware OS when using an external LDAP authentication server. Worse, the flaw can progress into UAF (Use-After-Free). The scary part? Attackers may be able to exploit it even without authentication to run arbitrary code. Beyond the RCE “big one,” there are 9 high-risk bugs (including CVE-2026-13084, CVSS v4: 8.7 NULL pointer dereference causing service interruption). Others range from NULL/validation bypass to memory corruption and path traversal—potentially escalating into RCE or arbitrary file writes. Versions impacted: Fireware OS 11.x, 12.x, 12.5.x, 2025.1.x. 11.x is out of support. For everything else, patch ASAP. This is not optional. #WatchGuard #Firebox #CyberSecurity #NetworkSecurity #Patching #RCE
