TITLE:
Drupal Code Execution and Cross-Site Request Forgery

SECUNIA ADVISORY ID:
SA27290

VERIFY ADVISORY:
http://secunia.com/advisories/27290/

CRITICAL:
Less critical

IMPACT:
Cross Site Scripting, System access

WHERE:
>From remote

SOFTWARE:
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 request forgery
attacks and to compromise a vulnerable system.

1) Input passed to unspecified parameters in install.php is not
properly sanitised. This can be exploited to execute arbitrary code.

Successful exploitation of this vulnerability requires that the
configured SQL server is not reachable.

2) A vulnerability is caused due to the application allowing users to
perform certain actions via HTTP requests without performing any
validity checks to verify the request. This can be exploited to
delete users by enticing a logged-in administrator to visit a
malicious site.

The vulnerabilities are reported in the 5.x branch before 5.3.

SOLUTION:
Update to version 5.3.
