SynopsisThe remote SSH server has an authentication bypass vulnerability.
DescriptionAccording to its banner, the version of OpenSSH running on the remote host is older than 3.2.3. It therefore may be affected by an authentication bypass issue. On systems using YP with netgroups, sshd authenticates users via ACL by checking for the requested username and password. Under certain conditions when doing ACL checks, it may instead use the password entry of a different user for authentication. This means unauthorized users could authenticate successfully, and authorized users could be locked out.
SolutionUpgrade to OpenSSH 3.2.3 or later.
