Descripción resumida

WatchGuard Fireware OS iked process contains an out of bounds write vulnerability in the OS iked process. This vulnerability may allow a remote unauthenticated attacker to execute arbitrary code and affects both the mobile user VPN with IKEv2 and the branch office VPN using IKEv2 when configured with a dynamic gateway peer.

Acción requerida

Apply mitigations per vendor instructions, follow applicable BOD 22-01 guidance for cloud services, or discontinue use of the product if mitigations are unavailable.

Notas

Check for signs of potential compromise on all internet accessible instances after applying mitigations. For more information please see: https://www.watchguard.com/wgrd-psirt/advisory/wgsa-2025-00027 ; https://nvd.nist.gov/vuln/detail/CVE-2025-14733

Descripción técnica

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.

0A weakness has been identified in D-Link DSM-G600 1.01. This affects an unknown function of the file /load_file.cgi of the component Multipart Handler. Executing a manipulation can lead to out-of-bounds write. The attack may be launched remotely. The exploit has been made available to the public and could be used for attacks.5h

1CVE-2025-40843 https://github.com/advisories/GHSA-5xf2-f6ch-6p8r  was fixed by replacing unchecked strcpy() with a bounded safe_strcpy() helper. At ldlogger-tool-gcc.c:129 the destination passed to that helper is fullPath + 2, but the size passed down is the full PATH_MAX. safe_strcpy() is strncpy(), which NUL-pads the destination out to the whole n, so this site writes 4096 bytes into the 4094 that remain — a 2-byte stack overflow on every invocation, independent of the input path's length. This issue affects CodeChecker: through 6.28.2.3d
