TITLE:
phpunity.postcard "gallery_path" Parameter File Inclusion

SECUNIA ADVISORY ID:
SA21897

VERIFY ADVISORY:
http://secunia.com/advisories/21897/

CRITICAL:
Highly critical

IMPACT:
System access

WHERE:
>From remote

SOFTWARE:
phpunity.postcard
http://secunia.com/product/11948/

DESCRIPTION:
Rivertam has discovered a vulnerability in phpunity.postcard, which
can be exploited by malicious people to compromise a vulnerable
system.

Input passed to the "gallery_path" parameter in phpunity-postcard.php
isn't properly verified, before it is used to include files. This can
be exploited to include arbitrary files from external and local
resources.

Example:
http://[host]/phpunity-postcard.php?plgallery_epost=1&gallery_path=[file]

Successful exploitation requires that "register_globals" is enabled.

The vulnerability has been confirmed in the latest available version.
Other versions may also be affected.

SOLUTION:
Edit the source code to ensure that input is properly verified.

Set "register_globals" to "Off".

PROVIDED AND/OR DISCOVERED BY:
