CVE-2025-9242
An Out-of-bounds Write vulnerability in the WatchGuard Fireware OS iked process may allow a remote unauthenticated attacker to execute arbitrary code. This vulnerability affects both the mobile user VPN with IKEv2 and the branch office VPN using IKEv2 when configured with a dynamic gateway peer.
If the Firebox was previously configured with the mobile user VPN with IKEv2 or a branch office VPN using IKEv2 to a dynamic gateway peer, and both of those configurations have since been deleted, that Firebox may still be vulnerable if a branch office VPN to a static gateway peer is still configured.

An FBX-5313 issue was discovered in WatchGuard Fireware before 12.0. When a failed login attempt is made to the login endpoint of the XML-RPC interface, if JavaScript code, properly encoded to be consumed by XML parsers, is embedded as value of the user element, the code will be rendered in the context of any logged in user in the Web UI visiting "Traffic Monitor" sections "Events" and "All." As a side effect, no further events will be visible in the Traffic Monitor until the device is restarted.
