Mercury SMTP Server AUTH CRAM-MD5 Remote Buffer Overflow

high Nessus Plugin ID 25928

Language:

Synopsis

The remote mail server is affected by a buffer overflow vulnerability.

Description

The remote host is running the Mercury Mail Transport System, a free suite of server products for Windows and NetWare associated with Pegasus Mail.

The version of Mercury Mail installed on the remote host includes an SMTP server that is affected by a buffer overflow flaw. Using a specially crafted 'AUTH CRAM-MD5' request, an unauthenticated, remote attacker can leverage this issue to crash the remote application and even execute arbitrary code remotely, subject to the privileges under which the application runs.

Solution

Upgrade to Mercury/32 v4.52 or later or apply the 4.01c / 1.49 security patch.
