Comment: This bulletin contains two (2) Drupal Security Advisories
Please note that a patch is not available for the Ajax Table
vulnerability. See the solution section below for mitigation
advice.
- --------------------------BEGIN INCLUDED TEXT--------------------
* Advisory ID: DRUPAL-SA-CONTRIB-2009-053
* Project: Ajax Table (third-party module)
* Version: 5.x
* Date: 2009-Aug-26
* Security risk: Critical
* Exploitable from: Remote
* Vulnerability: Multiple vulnerabilities
- -------- DESCRIPTION ---------------------------------------------------------
The Ajax Table module allows one to create AJAX-refreshable tables by
supplying a few parameters.
.... Access bypass
The module lacks access checks, which makes it possible for any user to
delete arbitrary users and nodes. The module contains a number of security
issues.
.... Cross site scripting
The module doesn't escape certain user supplied values. Malicious users can
use this to insert arbitrary HTML and script content into pages. Such a cross
site scripting [1] attack may even lead to the malicious user gaining
administrator access.
- -------- VERSIONS AFFECTED ---------------------------------------------------
* Ajax Table for Drupal 5.x
Drupal core is not affected. If you do not use the contributed Ajax Table
module, there is nothing you need to do.
- -------- SOLUTION ------------------------------------------------------------
There is no solution available. Please disable the module and remove it from
your server.

* Advisory ID: DRUPAL-SA-CONTRIB-2009-054
* Project: Go - url redirects (third-party module)
* Versions: 5.x, 6.x
* Date: 2009 August 26
* Security risk: Highly Critical
* Exploitable from: Remote
* Vulnerability: Multiple vulnerabilities
- -------- DESCRIPTION ---------------------------------------------------------
The Go - url redirects (gotwo) module adds the option to add redirected URLs.
This module was found to have multiple vulnerabilities.
.... Arbitrary PHP code execution
Due to improper use of the PCRE regular expression engine, users with
permission to use the input filter provided by the module are able to execute
arbitrary PHP code on the server.
.... Cross-site scripting (XSS)
User-supplied text is displayed in several places without being properly
filtered, allowing malicious users to inject arbitrary HTML and script code.
Such a cross site scripting [1] (XSS) attack may lead to a malicious user
gaining full administrative access.
.... Access bypass and cross-site request forgery
Due to coding errors, users may be able to add redirects or reset redirect
counters without having permission to do so.
- -------- VERSIONS AFFECTED ---------------------------------------------------
* Versions of "Go - url redirects" for Drupal 5.x prior to 5.x-1.4
* Versions of "Go - url redirects" for Drupal 6.x prior to 6.x-1.1
Drupal core is not affected. If you do not use the contributed "Go - url
redirects" module, there is nothing you need to do.
- -------- SOLUTION ------------------------------------------------------------
Install the latest version:
* If you use "Go - url redirects" for Drupal 5.x upgrade to Go - url
redirects 5.x-1.4 [2]
* If you use "Go - url redirects" for Drupal 6.x upgrade to Go - url
redirects 6.x-1.1 [3]
See also the Go - url redirects project page [4].
