CVE-2025-14733 is a critical out-of-bounds write vulnerability in the Internet Key Exchange daemon (iked) of WatchGuard Fireware OS on Firebox appliances. The flaw occurs while processing IKEv2 negotiations and can be triggered with crafted IKE_AUTH requests containing an abnormally large CERT payload. It affects Mobile User VPN using IKEv2 and Branch Office VPN using IKEv2 with a dynamic gateway peer. A device can also remain exposed after deletion of those configurations when a Branch Office VPN using a static gateway peer remains configured. Affected releases include Fireware OS 11.10.2 through 11.12.4_Update1, 12.0 through 12.11.5, and 2025.1 through 2025.1.3.

An out-of-bounds write vulnerability in WatchGuard Firebox that enables unauthenticated, pre-auth remote code execution against internet-facing VPN-related services. CISA lists it in KEV and has confirmed its use in ransomware campaigns; WatchGuard also confirmed attackers exfiltrated appliance configurations and management databases.
A critical unauthenticated remote-code-execution vulnerability caused by an out-of-bounds write in WatchGuard Firebox firewalls. It is actively exploited, including by ransomware groups, particularly where IKEv2 VPN is configured.
A critical unauthenticated remote-code-execution vulnerability in WatchGuard Firebox firewalls. It is an out-of-bounds write flaw exploitable through low-complexity attacks, principally affecting devices configured for IKEv2 VPN; certain branch-office VPN configurations may remain vulnerable even after deleting vulnerable configurations. CISA added it to the KEV catalog and reports ransomware-gang exploitation.
Critical out-of-bounds write in WatchGuard Fireware OS (iked process) enabling remote unauthenticated arbitrary code execution; exploited in real-world attacks per snippet.
