Synopsis
========
WordPress is vulnerable to SQL injection, information disclosure, and
cross-site scripting attacks.
Background
==========
WordPress is a popular personal publishing platform with a web
interface.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 www-apps/wordpress < 2.0.6 >= 2.0.6
Description
===========
When decoding trackbacks with alternate character sets, WordPress does
not correctly sanitize the entries before further modifying a SQL
query. WordPress also displays different error messages in wp-login.php
based upon whether or not a user exists. David Kierznowski has
discovered that WordPress fails to properly sanitize recent file
information in /wp-admin/templates.php before sending that information
to a browser.
Impact
======
An attacker could inject arbitrary SQL into WordPress database queries.
An attacker could also determine if a WordPress user existed by trying
to login as that user, better facilitating brute force attacks. Lastly,
an attacker authenticated to view the administrative section of a
WordPress instance could try to edit a file with a malicious filename;
this may cause arbitrary HTML or JavaScript to be executed in users'
browsers viewing /wp-admin/templates.php.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All WordPress users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=www-apps/wordpress-2.0.6"
