Summary
A buffer overflow in WatchGuard Fireware OS may allow an authenticated remote attacker with privileged management access to execute arbitrary code with system privileges on the firewall. This issue affects Fireware OS from 11.9.6 through 12.10.3.
Risk Assessment
An attacker with management privileges can gain full control of the firewall, potentially leading to network security compromise.
Recommendation
Upgrade WatchGuard Fireware OS to a version later than 12.10.3, which includes the fix.

- CVE-2025-14733CriticalActively exploited
An Out-of-bounds Write vulnerability in the WatchGuard Fireware OS iked process may allow a remote unauthenticated attacker to execute arbitrary code. It affects both mobile user VPN with IKEv2 and branch office VPN using IKEv2 when configured with a dynamic gateway peer. Even after deleting those configurations, if a branch office VPN to a static gateway peer remains, the Firebox may still be vulnerable.
