Courier Mail Server < 0.52.2 Deactivated Account Authentication Bypass

high Nessus Network Monitor Plugin ID 3322

Synopsis

The remote host may allow deactivated users to access their accounts using their old credentials.

Description

The remote host is running Courier Mail Server, an open source mail server for Linux and Unix. The installed version of Courier is prone to a bug in the way that it handles deactivated accounts. Versions of Courier less than 0.52.2 will still allow deactivated accounts to be accessed and used. An attacker exploiting this flaw would need to have the deactivated credentials in order to exploit this flaw.

Solution

Upgrade to Courier Mail Server 0.52.2 or higher.
