TITLE:
Moodle Script Insertion and Cross-Site Request Forgery

SECUNIA ADVISORY ID:
SA31196

VERIFY ADVISORY:
http://secunia.com/advisories/31196/

CRITICAL:
Less critical

IMPACT:
Cross Site Scripting

WHERE:
>From remote

SOFTWARE:
Moodle 1.6.x
http://secunia.com/product/11936/
Moodle 1.7.x
http://secunia.com/product/14720/

DESCRIPTION:
ProCheckUp Ltd have reported two vulnerabilities in Moodle, which can
be exploited by malicious users to conduct script insertion attacks,
and by malicious people to conduct cross-site request forgery
attacks.

1) Input passed to the "etitle" parameter in blog/edit.php is not
properly sanitised before being stored. This can be exploited to
insert arbitrary HTML and script code, which is executed in a user's
browser session in context of an affected site when the malicious
data is viewed.

Successful exploitation of this vulnerability requires valid user
credentials with the capability to add new blog entries, and that the
blog is enabled.

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
change an administrator's e-mail address, by enticing a logged-in
administrator to visit a malicious web page. This can further be
exploited to change the administrator's password and log in as the
administrator.

The vulnerabilities are reported in all 1.6.x versions before 1.6.7
and all 1.7.x versions before 1.7.5.

SOLUTION:
Update to version 1.6.7 or 1.7.5.
