CompreXX Archive Extraction Directory Traversal
------------------------------------------------------------------------


SUMMARY

<http://www.comprexx.com/> CompreXX allows "you to create any archive
type from the 28 available with a single right click, their plug-in based
product ships with 10 plug-ins that have full support for 28 archive types
and extract support for 47 archive types. You can add support for new
archive types by installing their plug-ins". A directory traversal
vulnerability has been found in CompreXX which allows attackers to
overwrite files that already exist in the operating system by supplying
files with a prefix of ../.

DETAILS

Vulnerable Systems:
* CompreXX version 4.1

The vulnerability is caused due to an input validation error when
extracting files compressed with RAR (.rar) , JAR (.jar) and ZIP (.zip).
This makes it possible to have files extracted to arbitrary locations
outside the specified directory (like StartUp) using the "../" directory
traversal sequence.
