A vulnerability was found in Drupal 6.33/7.33 (Content Management System) and classified as critical. Affected by this issue is some unknown functionality of the component Session Handler. The manipulation with an unknown input leads to a access control vulnerability. Using CWE to declare the problem leads to CWE-264. Impacted is integrity. CVE summarizes:

Drupal 6.x before 6.34 and 7.x before 7.34 allows remote attackers to hijack sessions via a crafted request, as demonstrated by a crafted request to a server that supports both HTTP and HTTPS sessions.

The weakness was disclosed 11/19/2014 by Aaron Averill as DRUPAL-SA-CORE-2014-006 as confirmed security advisory (Website). The advisory is shared for download at drupal.org. This vulnerability is handled as CVE-2014-9015 since 11/20/2014. The attack may be launched remotely. No form of authentication is required for exploitation. There are neither technical details nor an exploit publicly available. The MITRE ATT&CK project declares the attack technique as T1068. The advisory points out:

A specially crafted request can give a user access to another user's session, allowing an attacker to hijack a random session. This attack is known to be possible on certain Drupal 7 sites which serve both HTTP and HTTPS content ("mixed-mode"), but it is possible there are other attack vectors for both Drupal 6 and Drupal 7.

The vulnerability scanner Nessus provides a plugin with the ID 79386 (Drupal 6.x < 6.34 / 7.x < 7.34 Multiple Vulnerabilities), which helps to determine the existence of the flaw in a target environment. It is assigned to the family CGI abuses. The advisory illustrates:

If you have configured a custom session.inc file for your Drupal 6 or Drupal 7 site you also need to make sure that it is not prone to the same session hijacking vulnerability disclosed in this security advisory. If you have configured a custom password.inc file for your Drupal 7 site you also need to make sure that it is not prone to the same denial of service vulnerability disclosed in this security advisory.

Upgrading to version 6.34 or 7.34 eliminates this vulnerability. A possible mitigation has been published immediately after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at X-Force (98860) and Tenable (79386). seclists.org is providing further details. The entry 68253 is pretty similar.
