SSH 3 AllowedAuthentications Remote Bypass

This script is Copyright (C) 2002-2013 Tenable Network Security, Inc.

Synopsis :

The remote SSH server may accept password-based authentications even
when not explicitely enabled.

Description :

The remote host is running a version of SSH that is older than 3.1.2
and newer or equal to 3.0.0.

There is a vulnerability in this release that may, under some
circumstances, allow users to authenticate using a password whereas it
is not explicitly listed as a valid authentication mechanism.

An attacker may use this flaw to attempt to brute-force a password
using a dictionary attack (if the passwords used are weak).

Solution :

Upgrade to version 3.1.2 of SSH, which solves this problem.

Risk factor :

Low / CVSS Base Score : 3.5
CVSS Temporal Score : 2.6
