SA-2008-046 – Drupal core – Session fixation

Leave a comment
  • Advisory ID: DRUPAL-SA-2008-046
  • Project: Drupal core
  • Version: 5.x
  • Date: 2008-July-23
  • Security risk: Less critical
  • Exploitable from: Remote
  • Vulnerability: Session fixation

Description

When contributed modules such as Workflow NG terminate the current request during a login event, user module is not able to regenerate the user’s session. This may lead to a session fixation attack, when a malicious user is able to control another users’ initial session ID. As the session is not regenerated, the malicious user may use the ‘fixed’ session ID after the victim authenticates and will have the same access.

The advisory SA-2008-044 claims that this session fixation vulnerability was fixed in Drupal 5.8 and 6.3. Unfortunately, Drupal 5.8 still contains this vulnerability.

Versions affected

  • Drupal 5.x before version 5.9

Solution

Install the latest version:

  • If you are running Drupal 5.x then upgrade to Drupal 5.9.

If you are unable to upgrade immediately, you can apply a patch to secure your installation until you are able to do a proper upgrade. The patches fix security vulnerabilities, but do not contain other fixes which were released in these versions.

Reported by

  • The session fixation issue was originally reported by Erich C. Beyrent. Its continued existance in 5.8 was reported by dmnd.

New Feature – KUDOS

Leave a comment

Hi everyone,
 
There’s a new feature we’ve just implemented for the “Norton Forums BETA” – Kudos!
 
Kudos are a way for you to give approval to content that you think is helpful, well-formed, insightful, or otherwise generally valuable in the community. When you give kudos to a message, you are not only offering a thumbs up for good content, but also a pat on the back to its author. Kudos also allow Moderators and Administrators to identify and organize the content that you are likely to find most relevant.
 
Here’s how you do it: Simply click the “Kudos!” button to give a kudo to the message and its author. The author of a message cannot kudo his/her own messages; Also, you can only kudo a message once.

 

If you have any questions or concerns about this new feature, please let us know on the Forum Feedback Board. Thanks!

SA-2008-044 – Drupal core – Multiple vulnerabilities

Leave a comment
  • Advisory ID: DRUPAL-SA-2008-044
  • Project: Drupal core
  • Version: 5x, 6.x
  • Date: 2008-July-9
  • Security risk: Moderately critical
  • Exploitable from: Remote
  • Vulnerability: Multiple vulnerabilities

Description

Multiple vulnerabities and weaknesses were discovered in Drupal. Neither of these are readily exploitable.

Cross site scripting

Free tagging taxonomy terms can be used to insert arbitrary script and HTML code (cross site scripting or XSS) on node preview pages. A successful exploit requires that the victim selects a term containing script code and chooses to preview the node. This issue affects Drupal 6.x only.

Some values from OpenID providers are output without being properly escaped, allowing malicious providers to insert arbitrary script and HTML code (XSS) into user pages. This issue affects Drupal 6.x only.

filter_xss_admin() has been hardened to prevent use of the object HTML tag in administrator input.

Cross site request forgeries

Translated strings (5.x, 6.x) and OpenID identities (6.x) are immediately deleted upon accessing a properly formatted URL, making such deletion vulnerable to cross site request forgeries (CSRF). This may lead to unintended deletion of translated strings or OpenID identities when a sufficiently privileged user visits a page or site created by a malicious person.

Session fixation

When contributed modules such as Workflow NG terminate the current request during a login event, user module is not able to regenerate the user’s session. This may lead to a session fixation attack, when a malicious user is able to control another users’ initial session ID. As the session is not regenerated, the malicious user may use the ‘fixed’ session ID after the victim authenticates and will have the same access. This issue affects both Drupal 5 and Drupal 6.

SQL injection

Schema API uses an inappropriate placeholder for ‘numeric’ fields enabling SQL injection when user-supplied data is used for such fields.This issue affects Drupal 6 only.

Versions affected

  • Drupal 5.x before version 5.8
  • Drupal 6.x before version 6.3

Solution

Install the latest version:

  • If you are running Drupal 5.x then upgrade to Drupal 5.8.
  • If you are running Drupal 6.x then upgrade to Drupal 6.3.

If you are unable to upgrade immediately, you can apply a patch to secure your installation until you are able to do a proper upgrade. The patches fix security vulnerabilities, but do not contain other fixes which were released in these versions.

Note for site administrators

Drupal 5.8 and 6.3 no longer support the use of the object HTML tag in many text supplied by administrators. Such texts include the mission statement and taxonomy term descriptions.

Notes for developers

Drupal 6.3 has the new db_query placeholder %n for numeric fields (DECIMAL, NUMERIC). Custom queries should be updated to reflect this change.

Reported by

  • The session fixation issue was reported by Erich C. Beyrent.
  • The Taxonomy term XSS issue was reported by John Morahan.
  • The OpenID CSRF issue was reported by Peter Wolanin (Drupal security team).
  • The OpenID XSS issue was reported by Neil Drumm (Drupal security team).
  • The locale CSRF issue and the numeric SQL injection issue were reported by Heine Deelstra (Drupal security team).
