TITLE:

SECUNIA ADVISORY ID:

VERIFY ADVISORY:
http://secunia.com/advisories/33919/

CRITICAL:
Less critical

IMPACT:
Cross Site Scripting

WHERE:
>From remote

SOFTWARE:
Drupal Advertisement Module 5.x
http://secunia.com/advisories/product/21384/
Drupal Advertisement Module 6.x
http://secunia.com/advisories/product/21385/

DESCRIPTION:
Justin C. Klein Keane has reported a vulnerability in the
Advertisement module for Drupal, which can be exploited by malicious
users to conduct script insertion attacks.

Input passed to unspecified parameters is not properly sanitised
before being used. This can be exploited to insert arbitrary HTML and
script code, which will be executed in a user's browser session in the
context of an affected site when the malicious advertisement is
displayed.

Successful exploitation of this vulnerability requires the "create
advertisements" permission and that a user with the "administer
advertisements" permission configures the module to ignore Drupal's
standard input filters.

This vulnerability is reported in versions prior to 5.x-1.7 and
6.x-1.0-rc1.

SOLUTION:
Update to version 5.x-1.7 or 6.x-1.0-rc1.

PROVIDED AND/OR DISCOVERED BY:
The vendor credits Justin C. Klein Keane.
