Associated Vulnerability

Title: WatchGuard Firebox iked Out of Bounds Write Vulnerability (CVE-2025-9242)
Description: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.

Description

WatchGuard Fireware OS 11.10.2 to 11.12.4_Update1, 12.0 to 12.11.3, and 2025.1 contains an out-of-bounds write caused by improper handling in Mobile User VPN and Branch Office VPN with IKEv2 dynamic gateway peer, letting remote unauthenticated attackers execute arbitrary code.
