VID 14204
Severity 30
Port 22
Protocol TCP
Class SSH
Detailed Description According to its banner, the version of OpenSSH running on the remote host is prior to version 7.2. It is, therefore, affected by a security bypass vulnerability due to a flaw in ssh(1) that is triggered when it falls back from untrusted X11 forwarding to trusted forwarding when the SECURITY extension is disabled by the X server. This can result in untrusted X11 connections that can be exploited by a remote attacker.

* Note: This check solely relied on the banner of the remote SSH server to assess this vulnerability, so this might be a false positive.

* Platforms Affected:
OpenSSH version before 7.2
Any operating system Any version
Recommendation Upgrade to the latest version of OpenSSH (7.2 or later), available from the OpenSSH Web site at http://www.openssh.org/
