Advisory - Redirection Vulnerability in wp-login.php.

[Metaeye SG <contact () metaeye org>]

Vendor
------
Wordpress (http://www.wordpress.org).

Severity
--------
Moderate.

Dated
-----
03 March 2007.

Versions Affected
-----------------
All.

Issue
-----

The wp-login.php page redirects a user to arbitrary page after
successful login by setting the redirect_to url parameter.

For example if a user logins successfully with his credentials
on the following page

http://www.foo.com/wp-login.php?redirect_to=http://www.google.co.in

He will be redirected to www.google.co.in.

Impact
------

This can lead to credentials stealing. Also cookie stealing
is possible coupled with some browser bugs.
