MailEnable STATUS Command Overflow

High

Synopsis

The remote IMAP server is prone to buffer overflows.

Description

The remote host is running a version of MailEnable's IMAP service that is prone to a buffer overflow vulnerability triggered when processing a STATUS command with a long mailbox name. Once authenticated, an attacker can exploit this flaw to execute arbitrary code subject to the privileges of the affected application. In addition, the version of MailEnable is vulnerable to an IMAP directory traversal flaw. An attacker exploiting this flaw would need to be able to log into the server and issue a malformed ('../') request. Successful exploitation would result in the attacker accessing confidential data.

Solution

Upgrade to MailEnable Professional 1.7 or higher or to MailEnable Enterprise Edition 1.2 or higher.
