- ------------SA-2008-062 - SIOC - ACCESS BYPASS------------

  * Advisory ID: DRUPAL-SA-2008-062

  * Project: SIOC (third-party module)

  * Versions: 5.x and 6.x

  * Security risk: Moderately critical

  * Exploitable from: Remote

  * Vulnerability: Access bypass

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

The SIOC (Semantically-Interconnected Online Communities) project is an 
open specification for describing communities using online discussion 
forums or blogs, the module allows Drupal sites to attach metadata to 
users, posts, comments etc. in line with this specification.

The module doesn't implement Drupal's menu and database APIs correctly,
allowing unprivileged users to view comments, hashed emails, usernames 
and roles which they might otherwise not have access to.

- ------------VERSIONS AFFECTED------------

  * Versions of SIOC for Drupal 5.x prior to 5.x-1.2

  * Versions of SIOC for Drupal 6.x prior to 6.x-1.1

Drupal core is not affected. If you do not use the SIOC module, there is
nothing you need to do.

- ------------SOLUTION------------

Install the latest version.

  * If you use SIOC for Drupal 5.x upgrade to SIOC 5.x-1.2 [
http://drupal.org/node/318762 ]

  * If you use SIOC for Drupal 6.x upgrade to SIOC 6.x-1.1 [
http://drupal.org/node/318744 ]

Also see the SIOC project page [ http://drupal.org/project/sioc ].

  * Security risk: Highly critical

  * Exploitable from: Remote

  * Vulnerability:SQL injection, Cross-site scripting (XSS), Privilege
    escalation, access bypass

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

handling of user submitted data, leading to a number of vulnerabilities. Of
special concern is that an unprivileged user may become logged in to the account
of an existing user, including an administrator.

- ------------VERSIONS AFFECTED------------

  * All versions of EveryBlog

Drupal core is not affected. If you do not use the EveryBlog module, there is
nothing you need to do.

- ------------SOLUTION------------
