Gentoo Linux Security Advisory

Title: WordPress: Multiple vulnerabilities (GLSA 200701-10)
Severity: normal
Exploitable: remote
Date: January 15, 2007
Bug(s): #159229
ID: 200701-10

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: www-apps/wordpress
Vulnerable: < 2.0.6
Unaffected: >= 2.0.6
Architectures: All supported architectures


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:
Code:
# emerge --sync
# emerge --ask --oneshot --verbose ">=www-apps/wordpress-2.0.6"
