TITLE:
Drupal OpenID Module Vulnerabilities

SECUNIA ADVISORY ID:
SA31027

VERIFY ADVISORY:
http://secunia.com/advisories/31027/

CRITICAL:
Less critical

IMPACT:
Cross Site Scripting

WHERE:
>From remote

SOFTWARE:
Drupal OpenID Module 5.x
http://secunia.com/product/17404/

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

1) Certain input passed from the OpenID provider is not properly
sanitised before being returned to a user. This can be exploited to
execute arbitrary HTML and script code in a user's browser session in
context of an affected site.

2) The module allows users to perform certain actions via HTTP
requests without performing any validity checks to verify the
request. This can be exploited to e.g. delete OpenID identities by
enticing a logged-in user to visit a malicious site.

The vulnerabilities affect versions prior to 5x.-1.2.

SOLUTION:
Update to version 5x.-1.2.
