OPIE w/ OpenSSH Account Enumeration

medium Nessus Plugin ID 17705

Language:

Synopsis

The remote host is susceptible to an information disclosure attack.

Description

When using OPIE for PAM and OpenSSH, it is possible for remote attackers to determine the existence of certain user accounts.

Note that Nessus has not tried to exploit the issue, but rather only checked if OpenSSH is running on the remote host. As a result, it does not detect if the remote host actually has OPIE for PAM installed.

Solution

A patch currently does not exist for this issue. As a workaround, ensure that OPIE for PAM is not installed.
