TITLE:
Drupal Multiple Vulnerabilities

SECUNIA ADVISORY ID:
SA22486

VERIFY ADVISORY:
http://secunia.com/advisories/22486/

CRITICAL:
Less critical

IMPACT:
Hijacking, Cross Site Scripting

WHERE:
>From remote

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

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

1) Some unspecified input is not properly sanitised in the XML parser
before being used. This can be exploited to execute arbitrary HTML and
script code in a user's browser session in context of an affected site
via a specially crafted RSS feed.

Successful exploitation requires that the PHP "mbstring" extension is
disabled.

2) Some unspecified input is not properly sanitised before being used
in the "aggregator", "profile", and "forum" module. 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.

3) An error exists due to the application allowing users to perform
certain actions via HTTP requests without performing any validity
checks to verify the user's request. This can e.g. be exploited to
change passwords, post PHP code, or create new users.

4) Some input to unspecified parameters is not properly sanitised
before being returned to the user. This can be exploited to redirect
a user's form submission to an attackers site when the user is
tricked to use a specially crafted link.

The vulnerabilities are reported in versions prior to 4.6.10 and
4.7.4.

SOLUTION:
Update to version 4.6.10 or 4.7.4, or later.
