GLSA 200701-10: WordPress: Multiple vulnerabilities

Severity:normal
Title:WordPress: Multiple vulnerabilities
Date:01/15/2007
Bugs: #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 Vulnerable Unaffected Architecture(s)
www-apps/wordpress < 2.0.6 >= 2.0.6 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:

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