SYSTEM privilege escalation via incorrect resource permissions
Published Jul 2, 2026 · Updated Jul 2, 2026
Privilege escalation in WatchGuard Mobile VPN with SSL client for Windows 2026.2 and earlier allows local users to gain SYSTEM access. WatchGuard identifies incorrect permissions on a security-critical resource but has not disclosed the resource, permission setting, or triggering operation. Exploitation requires existing low-privileged local access; successful abuse grants NT AUTHORITY\SYSTEM control of the Windows host.
