* Advisory ID: DRUPAL-SA-CONTRIB-2009-061
* Project: Markdown Preview (third-party module)
* Version: 6.x
* Date: 2009 September 23
* Security risk: Less critical
* Exploitable from: Remote
* Vulnerability: Cross Site Scripting
-------- DESCRIPTION
---------------------------------------------------------
The Markdown Preview module provides a live preview pane that displays the
rendered HTML output of your Markdown input. When displaying the live
preview, the module does not properly escape user entered data, leading to a
cross-site scripting (XSS [1]) vulnerability. Such an attack may lead to a
malicious user gaining full administrative access.
-------- VERSIONS AFFECTED
---------------------------------------------------
* Markdown Preview for Drupal 6.x
Drupal core is not affected. If you do not use the contributed Markdown
Preview module, there is nothing you need to do.
-------- SOLUTION
------------------------------------------------------------
The Markdown Preview module has been abandoned and its releases have been
unpublished. It is recommended that it be disabled and removed from your
server if in use. For Markdown live preview functionality for nodes and
comments, use the Live module [2], which properly escapes the user entered
data using the content's current input format. See the Markdown Preview
project page [3] for instructions how to enable Markdown preview
functionality with the Live module [4].

* Project: OpenID (third-party module)
* Version: 5.x
* Date: 2009-September-16
* Security risk: Critical
* Exploitable from: Remote
* Vulnerability: Impersonation, cross site request forgery
-------- DESCRIPTION
---------------------------------------------------------
The contributed OpenID module for Drupal 5 allows users to create an account
or log into a Drupal site using one or more OpenID identities. The module
does not correctly implement Form API for the form that allows one to link
user accounts with OpenID identifiers. A malicious user is therefore able to
use cross site request forgeries [1] to add attacker controlled OpenID
identities to existing accounts. These OpenID identities can then be used to
gain access to the affected accounts.
.... OpenID impersonation
The OpenID module is not a compliant implementation of the OpenID
Authentication 2.0 specification. An implementation error allows a user to
access the account of another user when they share the same OpenID 2.0
provider.
-------- VERSIONS AFFECTED
---------------------------------------------------
* OpenID for Drupal 5.x prior to 5.x-1.3
Drupal 6.x core has a similar issue, see SA-CORE-2009-008 [2] for details.
-------- SOLUTION
------------------------------------------------------------
Upgrade to the latest version:
* If you use OpenID for Drupal 5.x upgrade to OpenID 5.x-1.3 [3]
*Important note*: Some users using OpenID might not be able to use the
existing OpenID associations to login after the upgrade. These users should
use the one time login via password recovery to get access to their user
account and re-add desired associations. These users likely had issues with
OpenID logins prior to the upgrade. See also the OpenID project page [4].
-------- REPORTED BY
---------------------------------------------------------
The OpenID impersonation was reported by Robert Metcalf [5]. The OpenID
association CSRF was reported by Heine Deelstra [6] (*). (*) Member of the
Drupal security team.

* Version: 5.x, 6.x
* Date: 2009-September-16
* Security risk: Critical
* Exploitable from: Remote
* Vulnerability: Multiple vulnerabilities
-------- DESCRIPTION
---------------------------------------------------------
Multiple vulnerabilities and weaknesses were discovered in Drupal.
.... OpenID association cross site request forgeries
The OpenID module in Drupal 6 allows users to create an account or log into a
Drupal site using one or more OpenID identities. The core OpenID module does
not correctly implement Form API for the form that allows one to link user
accounts with OpenID identifiers. A malicious user is therefore able to use
cross site request forgeries [1] to add attacker controlled OpenID identities
to existing accounts. These OpenID identities can then be used to gain access
to the affected accounts. This issue affects Drupal 6.x only.
.... OpenID impersonation
The OpenID module is not a compliant implementation of the OpenID
Authentication 2.0 specification. An implementation error allows a user to
access the account of another user when they share the same OpenID 2.0
provider. This issue affects Drupal 6.x only.
.... File upload
File uploads with certain extensions are not correctly processed by the File
API. This may lead to the creation of files that are executable by Apache.
The .htaccess that is saved into the files directory by Drupal should
normally prevent execution. The files are only executable when the server is
configured to ignore the directives in the .htaccess file. This issue affects
Drupal 6.x only.
.... Session fixation
Drupal doesn't regenerate the session ID when an anonymous user follows the
one time login link used to confirm email addresses and reset forgotten
passwords. This enables a malicious user to fix and reuse the session id of a
victim under certain circumstances. This issue affects Drupal 5.x only.
-------- VERSIONS AFFECTED
---------------------------------------------------
* Drupal 6.x before version 6.14.
* Drupal 5.x before version 5.20.
-------- SOLUTION
------------------------------------------------------------
Install the latest version:
* If you are running Drupal 6.x then upgrade to Drupal 6.14 [2].
* If you are running Drupal 5.x then upgrade to Drupal 5.20 [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. Theses patches
fix the security vulnerabilities, but do not contain other fixes which were
released in Drupal 6.14 or Drupal 5.20.
* To patch Drupal 6.13 use SA-CORE-2009-008-6.13.patch [4].
* To patch Drupal 5.19 use SA-CORE-2009-008-5.19.patch [5].
*Important note*: Some users using OpenID might not be able to use the
existing OpenID associations to login after the upgrade. These users should
use the one time login via password recovery to get access to their user
account and re-add desired associations. These users likely had issues with
OpenID logins prior to the upgrade.
-------- REPORTED BY
---------------------------------------------------------
The session fixation issue was reported by Noel Sharpe [6]. OpenID
impersonation was reported by Robert Metcalf [7]. OpenID association CSRF was
reported by Heine Deelstra [8] (*). The file upload issue was reported by

* 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
