high Nessus Network Monitor Plugin ID 1085

Synopsis

The remote host is vulnerable to a buffer overflow.

Description

According to its banner, the remote Cyrus IMAP server is vulnerable to a pre-login buffer overrun. An attacker without a valid login could exploit this, and would be able to execute arbitrary commands as the owner of the Cyrus process. This would allow full access to all users' mailboxes.
