AI Analysis
Technical Summary
CVE-2026-13368 is a critical use-after-free vulnerability caused by a race condition in the LDAP authentication mechanism of WatchGuard Fireware OS's Mobile User VPN with IKEv2. An unauthenticated remote attacker can exploit this vulnerability to execute arbitrary code within the iked process on Fireboxes that use an external LDAP authentication server. The affected versions include Fireware OS 11.0 up to 11.12.4_Update1, 12.0 up to 12.12, and 2025.1 up to 2026.2. No patch or official remediation information is provided in the data, and no known exploits in the wild have been reported.
Potential Impact
Successful exploitation allows remote unauthenticated attackers to execute arbitrary code with the privileges of the iked process, potentially leading to full compromise of the affected Firebox device. This impacts confidentiality, integrity, and availability of the device and its VPN services.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. In the absence of an official fix, consider disabling Mobile User VPN with IKEv2 LDAP authentication or restricting access to the VPN service until a patch is available.
