OpenSSH 7.x < 7.1 PermitRootLogin Security Bypass
Low Nessus Plugin ID 85690
SynopsisThe SSH server running on the remote host is affected by a security bypass vulnerability.
DescriptionAccording to its banner, the version of OpenSSH running on the remote host is 7.x prior to 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.
SolutionUpgrade to OpenSSH 7.1 or later.
