TITLE:
Drupal Cross-Site Request Forgery and Script Insertion

SECUNIA ADVISORY ID:
SA33112

VERIFY ADVISORY:
http://secunia.com/advisories/33112/

CRITICAL:
Moderately critical

IMPACT:
Cross Site Scripting

WHERE:
>From remote

SOFTWARE:
Drupal 6.x
http://secunia.com/advisories/product/17839/
Drupal 5.x
http://secunia.com/advisories/product/13378/

DESCRIPTION:
Some vulnerabilities have been reported in Drupal, which can be
exploited by malicious people to conduct cross-site request forgery
and cross-site scripting attacks.

1) The application allows users to perform certain actions via HTTP
requests without performing any validity checks to verify the
requests. This can be exploited to perform certain operations (e.g.
execute old updates) when a logged-in superuser visits a malicious
web site.

2) The application does not completely remove deleted input formats.
This can be exploited to execute arbitrary HTML and script code in a
user's browser session in the context of an affected site.

These vulnerabilities are reported in versions prior to 5.13 and 6.7.

SOLUTION:
Update for version 5.13 or 6.7.

PROVIDED AND/OR DISCOVERED BY:
The vendor credits David Rothstein.
