• Advisory ID: SA-CONTRIB-2010-079
  • Project: Devel (third-party module)
  • Version: 5.x, 6.x
  • Date: 2010-Aug-04
  • Security risk: Moderately critical
  • Exploitable from: Remote
  • Vulnerability: Cross Site Scripting


The devel project is a suite of modules for developers and themers.

Within the devel project, there is the performance logging module. The module does not escape URLs comprised of node paths, leading to a Cross Site Scripting (XSS) vulnerability. Users with the permission to access the reports that the performance module produces are vulnerable to attack. A malicious user needs the ability to add url aliases to create and exploit the vulnerability.

Versions affected:

  • Devel module for Drupal 5.x versions prior to 5.x-1.3
  • Devel module for Drupal 6.x versions prior to 6.x-1.21

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