TITLE:
Drupal Multiple Vulnerabilities

SECUNIA ADVISORY ID:
SA28422

VERIFY ADVISORY:
http://secunia.com/advisories/28422/

CRITICAL:
Moderately critical

IMPACT:
Cross Site Scripting

WHERE:
>From remote

SOFTWARE:
Drupal 4.x
http://secunia.com/product/342/
Drupal 5.x
http://secunia.com/product/13378/

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

1) Input passed via unspecified parameters to theme .tpl.php files is
not properly sanitised before being returned to the user. This can be
exploited to execute arbitrary HTML and script code in a user's
browser session in context of an affected site.

Successful exploitation requires that "register_globals" is enabled,
and the .htaccess file fails to prevent access to .tpl.php files and
to disable "register_globals".

2) An error in the text filtering functionality can be exploited to
bypass the filter via invalid UTF-8 sequences. This can be exploited
to insert arbitrary HTML and script code, which will be executed in a
user's browser session in context of an affected site when the
malicious data is viewed with e.g. Internet Explorer 6.

3) The aggregator module allows users to perform certain actions via
HTTP GET requests without performing any validity checks to verify
the request. This can be exploited to e.g. remove items from a
particular feed when a user visits a specially crafted page.

The vulnerabilities are reported in versions prior to 4.7.11 and 5.6.

SOLUTION:
Update to 4.7.11 or 5.6.
