Category: Debian Local Security Checks Risk factor: High Added: 16 Mar 2010
Synopsis:

The remote host is missing the DSA-2016 security update

Description:

Several vulnerabilities (SA-CORE-2010-001) have been discovered in drupal6, a fully-featured content management framework. A user-supplied value is directly output during installation allowing a malicious user to craft a URL and perform a cross-site scripting attack. The exploit can only be conducted on sites not yet installed. The API function drupal_goto() is susceptible to a phishing attack. An attacker could formulate a redirect in a way that gets the Drupal site to send the user to an arbitrarily provided URL. No user submitted data will be sent to that URL. Locale module and dependent contributed modules do not sanitize the display of language codes, native and English language names properly. While these usually come from a preselected list, arbitrary administrator input is allowed.
This vulnerability is mitigated by the fact that the attacker must have a role with the 'administer languages' permission. Under certain circumstances, a user with an open session that is blocked can maintain his/her session on the Drupal site, despite being blocked. For the stable distribution (lenny), these problems have been fixed in version 6.6-3lenny5.
