  • Advisory ID: DRUPAL-SA-CONTRIB-2012-043
  • Project: MultiBlock (third-party module)
  • Version: 6.x, 7.x
  • Date: 2012-March-28
  • Security risk: Moderately critical
  • Exploitable from: Remote
  • Vulnerability: Cross Site Scripting

Description

CVE: CVE-2012-2070

The MultiBlock module allows an administrator to create multiple instances of blocks provided by other modules. The module does not properly sanitize the block title provided by a block administrator, leading to a cross-site scripting (XSS) vulnerability. Such an attack may lead to a malicious user gaining full administrative access. A user must have a role with the permission 'administer blocks' to exploit this vulnerability.

Versions affected

  • MultiBlock 6.x-1.x versions prior to 6.x-1.4.
  • MultiBlock 7.x-1.x versions prior to 7.x-1.1.

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

Solution

Install the latest version:

  • If you use the MultiBlock module for Drupal 6.x, upgrade to MultiBlock 6.x-1.4
  • If you use the MultiBlock module for Drupal 7.x, upgrade to MultiBlock 7.x-1.1
