TITLE:
Marshal MailMarshal ARJ Archive Directory Traversal

SECUNIA ADVISORY ID:
SA22806

VERIFY ADVISORY:
http://secunia.com/advisories/22806/

CRITICAL:
Highly critical

IMPACT:
System access

WHERE:
>From remote

SOFTWARE:
MailMarshal for Exchange 5.x
http://secunia.com/product/2194/
MailMarshal SMTP 2006
http://secunia.com/product/12557/
MailMarshal SMTP 5.x
http://secunia.com/product/2193/
MailMarshal SMTP 6.x
http://secunia.com/product/6032/

DESCRIPTION:
A vulnerability has been reported in MailMarshal SMTP and MailMarshal
Exchange, which can be exploited by malicious people to compromise a
vulnerable system.

An input validation error during the extraction and scanning of ARJ
archives can be exploited to cause a file with a filename containing
directory traversal modifiers to be extracted to an arbitrary
directory on the system (e.g. the "All Users" startup folder).

SOLUTION:
Users of MailMarshal SMTP should update to version 2006, release
6.1.8.

A fix is not currently available for MailMarshal Exchange, but will
be included in the next service release. As a workaround, the vendor
suggests creating a separate disk partition used only for MailMarshal
unpacking folders.

PROVIDED AND/OR DISCOVERED BY:
Discovered by an anonymous person and reported via ZDI.
