Marshal MailMarshal ARJ Archive Directory Traversal Advisory Available in Danish  Advisory Available in German 

Secunia Advisory: SA22806  
Release Date: 2006-11-12

Critical:
Highly critical
Impact: System access
Where: From remote
Solution Status: Vendor Workaround

Software:MailMarshal for Exchange 5.x
MailMarshal SMTP 2006
MailMarshal SMTP 5.x
MailMarshal SMTP 6.x

CVE reference:CVE-2006-5487 (Secunia mirror)



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.
