Title: WordPress: Multiple vulnerabilities (GLSA 200703-23)
Severity: low
Exploitable: remote
Date: March 20, 2007
Bug(s): #168529
ID: 200703-23

Synopsis


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


Background


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


Affected Packages

Package: www-apps/wordpress
Vulnerable: <= 2.1.2
Architectures: All supported architectures


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.


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.
