Synopsis

Wordpress contains several cross-site scripting, cross-site request forgery and information leak vulnerabilities.

2.  Impact Information

Background

WordPress is a popular personal publishing platform with a web interface.

Description

WordPress contains cross-site scripting or cross-site scripting forgery vulnerabilities reported by:

  • g30rg3_x in the "year" parameter of the wp_title() function
  • Alexander Concha in the "demo" parameter of wp-admin/admin.php
  • Samenspender and Stefan Friedli in the "post" parameter of wp-admin/post.php and wp-admin/page.php, in the "cat_ID" parameter of wp-admin/categories.php and in the "c" parameter of wp-admin/comment.php
  • PsychoGun in the "file" parameter of wp-admin/templates.php

Additionally, WordPress prints the full PHP script paths in some error messages.

Impact

The cross-site scripting vulnerabilities can be triggered to steal browser session data or cookies. A remote attacker can entice a user to browse to a specially crafted web page that can trigger the cross-site request forgery vulnerability and perform arbitrary WordPress actions with the permissions of the user. Additionally, the path disclosure vulnerability could help an attacker to perform other attacks.

3.  Resolution Information

Workaround

There is no known workaround at this time for all these vulnerabilities.

Resolution

Due to the numerous recently discovered vulnerabilities in WordPress, this package has been masked in the portage tree. All WordPress users are advised to unmerge it.

Code Listing 3.1: Resolution

# emerge --unmerge "www-apps/wordpress"
