TITLE:
Drupal Multiple Vulnerabilities

SECUNIA ADVISORY ID:
SA36781

VERIFY ADVISORY:
http://secunia.com/advisories/36781/

DESCRIPTION:
Some vulnerabilities have been reported in Drupal, which can be
exploited by malicious users to hijack accounts and compromise a
vulnerable system, and by malicious people to conduct cross-site
request forgery attacks.

1) The OpenID module allows users to perform certain actions via HTTP
requests without performing any validation checks to verify the
requests. This can be exploited to e.g. add OpenID identities to
existing accounts.

2) An unspecified error within the OpenID Authentication 2.0
implementation can be exploited to hijack another user's account if
the same OpenID 2.0 provider is used.

3) An error within the File API when processing certain file
extensions can be exploited to e.g. upload files which can be
executed by the web server.

Note: Successful exploitation requires that the web server is
configured to ignore Drupal's ".htaccess" file.

The vulnerabilities are reported in versions prior to 6.14.

SOLUTION:
Update to version 6.14 or apply the patch.

Drupal 6.14:
http://ftp.drupal.org/files/projects/drupal-6.14.tar.gz

Patch:
http://drupal.org/files/sa-core-2009-008/SA-CORE-2009-008-6.13.patch

PROVIDED AND/OR DISCOVERED BY:
