DESCRIPTION:
Secunia Research has discovered a vulnerability in Macallan Mail
Solution, which can be exploited by malicious users to bypass certain
security restrictions and to gain access to potentially sensitive
information.

The vulnerability is caused due to directory traversal errors in the
CREATE, SELECT, DELETE and RENAME commands of the IMAP service. This
can be exploited by an authenticated user to read other users'
emails, create/rename arbitrary directories on the system, and delete
empty directories.

The vulnerability has been confirmed in version 4.8.03.025. Prior
versions may also be affected.

SOLUTION:
Update to version 4.8.05.004.
