VID 14102
Severity 20
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 7.1. It is, therefore, affected by a security bypass vulnerability due to a logic error that is triggered under certain compile-time configurations when PermitRootLogin is set to 'prohibit-password' or 'without-password'. An unauthenticated, remote attacker can exploit this to permit password authentication to root while preventing other forms of authentication.

* 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 7.1
Any operating system Any version
Recommendation Upgrade to the latest version of OpenSSH (7.1 or later), available from the OpenSSH Web site at http://www.openssh.org/
