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.

In exception circumstances, WatchGuard Fireware OS on a FireCluster may use a hard-coded encryption key to encrypt saved credentials for Access Portal resources.

This vulnerability does not affect devices that do not support the Access Portal feature or standalone Fireboxes not deployed in a FireCluster.

A path traversal vulnerability in the WatchGuard Fireware OS Management Web UI allows a privileged authenticated attacker to write arbitrary files on the Firebox's filesystem.

This issue affects the Mobile VPN with SSL client for Windows up to and including 2026.2.

An Out-of-bounds Write vulnerability in WatchGuard Fireware OS's CLI could allow an authenticated privileged user to execute arbitrary code via a specially crafted CLI command.

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.
