Comment: This bulletin contains three (3) Drupal Security Advisories
- --------------------------BEGIN INCLUDED TEXT--------------------
* Advisory ID: DRUPAL-SA-CONTRIB-2009-015
* Project: Token authentication (third-party module)
* Version: 6.x
* Date: 2009-March-25
* Security risk: Less critical
* Exploitable from: Remote
* Vulnerability: Access bypass
- -------- DESCRIPTION -------------------------------------------------------
The Token authentication module allows access to RSS feeds via a token
without having to provide your username and password to the site. Token
authentication did not properly use the Drupal Form API which would allow a
malicious user to learn the site administrator's token giving them the
ability to read any nodes on the site via an RSS feed.
- -------- VERSIONS AFFECTED -------------------------------------------------
* Token authentication 6.x-1.x prior to 6.x-1.1
Token authentication for Drupal 5.x is not affected by this vulnerability.
Drupal core is not affected. If you do not use the contributed Token
authentication module, there is nothing you need to do.
- -------- SOLUTION ----------------------------------------------------------
Upgrade to the latest version:
* If you use Token authentication 6.x-1.x upgrade to Token authentication
6.x-1.1 [1]
See also the Token authentication project page [2].

* Advisory ID: DRUPAL-SA-CONTRIB-2009-016
* Project: Wikitools (third-party module)
* Version: 5.x, 6.x
* Date: 2009-March-25
* Security risk: Less critical
* Exploitable from: Remote
* Vulnerability: Cross-site scripting
- -------- DESCRIPTION -------------------------------------------------------
The Wikitools module provides several options to get a more wiki-like
behavior for Drupal. On several pages, the Wikitools module prints out a
parameter without escaping it. Malicious users are thus able to execute a
cross site scripting [1] (XSS) attack when they entice users to visit a
specifically crafted URL. This may lead to a malicious user gaining full
administrative access.
- -------- VERSIONS AFFECTED -------------------------------------------------
* Wikitools 5.x-1.x prior to 5.x-1.3
* Wikitools 6.x-1.x prior to 6.x-1.1
Drupal core is not affected. If you do not use the contributed Wikitools
module, there is nothing you need to do.
- -------- SOLUTION ---------------------------------------------------------
Install the latest version:
* If you use Wikitools 5.x-1.x upgrade to Wikitools 5.x-1.3 [2]
* If you use Wikitools 6.x-1.x upgrade to Wikitools 6.x-1.1 [3]

* Advisory ID: DRUPAL-SA-CONTRIB-2009-017
* Project: Vote Up/Down (third-party module)
* Version: 5.x, 6.x
* Date: 2009-March-25
* Security risk: Not critical
* Exploitable from: Remote
* Vulnerability: Cross-site request forgery
- -------- DESCRIPTION ------------------------------------------------------
The Vote Up/Down module provides a voting widget for content that records
votes using Ajax. The URL for voting is vulnerable to cross-site request
forgeries (CSRF [1]) making it possible for users to unknowingly vote for
content.
- -------- VERSIONS AFFECTED -------------------------------------------------
* Vote Up/Down 5.x-1.x prior to 5.x-1.1
* Vote Up/Down 6.x-1.x prior to 6.x-1.0-beta4
Drupal core is not affected. If you do not use the contributed Vote Up/Down
module, there is nothing you need to do.
- -------- SOLUTION ----------------------------------------------------------
Install the latest version:
* If you use Vote Up/Down 5.x-1.x upgrade to Vote Up/Down 5.x-1.1 [2]
* If you use Vote Up/Down 6.x-1.x upgrade to Vote Up/Down 6.x-1.0-beta4 [3]
