critical Nessus Plugin ID 321197

Synopsis

The remote host is missing a vendor-supplied security patch.

Description

The version of Gaia Operating System installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the sk185033 advisory.

 - A logic flow weakness in Remote Access and Mobile Access certificate validation in deprecated IKEv1 key exchange allows an unauthenticated remote attacker to bypass user authentication and establish a remote access VPN connection without a valid user password. (CVE-2026-50751)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
