CVE-2025-14733

Summary

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.

Workarounds

If your Firebox is only configured with Branch Office VPN tunnels to static gateway peers and you are not able to immediately upgrade the device to a version of Fireware OS with the vulnerability resolution, you can follow WatchGuard’s recommendations for Secure Access to Branch Office VPNs that Use IPSec and IKEv2 (https://techsearch.watchguard.com/KB?type=Article&amp;SFDCID=kA1Vr000000DMXNKA4&amp;lang=en_US) as a temporary workaround.
