| Detailed Description |
According to its banner, the version of OpenSSH running on the remote host is prior to version 7.2p2. It is, therefore, affected by a security bypass vulnerability due to improper sanitization of X11 authentication credentials. An authenticated, remote attacker can exploit this, via crafted credentials, to inject arbitrary xauth commands, resulting in gaining read and write access to arbitrary files, connecting to local ports, or performing further attacks on xauth itself. Note that exploiting this vulnerability requires X11Forwarding to have been enabled.
* Note: This check solely relied on the banner of the remote SSH server to assess this vulnerability, so this might be a false positive.
