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 incorrect authorization vulnerability in the protocol communication between the WatchGuard Authentication Gateway (aka Single Sign-On Agent) on Windows and the WatchGuard Single Sign-On Client on Windows and MacOS allows an attacker with network access to forge communications to affected components.
In the event an attacker has already gained network access, they could exploit this vulnerability to retrieve authenticated usernames and group memberships from the Single Sign-On Agent or send arbitrary account and group information to the Single Sign-On Agent for their host. This vulnerability cannot be used by an attacker to gain access to user credentials.
