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.
Summary dbcve.org
An out-of-bounds write vulnerability in the iked process of WatchGuard Fireware OS allows remote unauthenticated attackers to execute arbitrary code via IKEv2 connections. Affected configurations include mobile user VPN with IKEv2 and branch office VPN using IKEv2 with dynamic gateway peers. The vulnerability persists even after deleting these VPN configurations if a branch office VPN to a static gateway peer remains configured.
Mitigation
Immediately disable or remove all IKEv2 VPN configurations (mobile user VPN and branch office VPN with dynamic gateway peers). Even after deletion, verify that no static gateway peer VPN configurations remain, as the vulnerability may persist in that scenario.
