[Security-news] SA-CONTRIB-2010-103 - Node Relativity - Multiple vulnerabilities

[security-news at drupal.org]

  * Advisory ID: DRUPAL-SA-CONTRIB-2010-103
  * Project: Node Relativity (third-party module)
  * Version: 5.x, 6.x
  * Date: 2010-November-10
  * Security risk: Critical
  * Exploitable from: Remote
  * Vulnerability: Cross-Site Scripting, Cross Site Request Forgery, Access
    bypass

-------- DESCRIPTION  
---------------------------------------------------------

The Node Relativity module allows parent-child relationships between nodes to
be established, managed and searched. The Node Relativity module does not
sanitize some of the user supplied data before displaying it, leading to a
Cross Site Scripting (XSS [1]) vulnerability which can be used by a malicious
user to gain full administrative access. The Node Relativity module does not
protect the links to establish relations between nodes against Cross-site
Request Forgeries (CSRF [2]) vulnerability which can be used by a malicious
user to directly perform operations on the database. The Node Relativity
module does not implement node access logic properly, resulting in the
display of node titles and the establishing of relations between nodes the
user has no access to.
-------- VERSIONS AFFECTED  
---------------------------------------------------

  * Node Relativity module for Drupal 5.x versions prior to 5.x-2.6
  * Node Relativity module for Drupal 6.x versions prior to 6.x-1.4
