GLSA-200701-10 : WordPress: Multiple vulnerabilities
Medium Nessus Plugin ID 24208
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-200701-10 (WordPress: Multiple vulnerabilities)
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.
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;
There is no known workaround at this time.
SolutionAll WordPress users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=www-apps/wordpress-2.0.6'
