Mercur Mailserver/Messaging version <= 5.0 IMAP Overflow Vulnerability

Vulnerability Assessment Summary
Checks for buffer overflows in Mercur Mailserver/Messaging IMAP Services

Detailed Explanation for this Vulnerability Assessment

Summary :

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

Description :

The remote host is running MERCUR Messaging Server / Mailserver, a
commercial messaging application for Windows.

The IMAP server component of this software fails to properly copy
overly-long arguments to LOGIN and SELECT commands, which can be
exploited to crash the server and possibly to execute arbitrary code
remotely.

Note that the services run by default with LOCAL SYSTEM rights,
which means that an unauthenticated attacker can potentially gain
complete control of the affected host.

Solution :

No patch information at this time.

Filter access to the IMAP4 Service, so that it can be used by trusted
sources only.

Network Security Threat Level:

High / CVSS Base Score : 7.0
