  • Advisory ID: DRUPAL-SA-CONTRIB-2014-023
  • Project: Project Issue File Review (third-party module)
  • Version: 6.x
  • Date: 2014-February-26
  • Security risk: Moderately critical
  • Exploitable from: Remote
  • Vulnerability: Cross Site Scripting

Description

The Project Issue File Review (PIFR) module provides an abstracted client-server model and plugin API for performing distributed operations such as code review and testing, with a focus on supporting Drupal development.

Two scenarios were identified where the module does not sufficiently sanitize user provided input, exposing the 'server' component of the module to cross-site scripting vulnerabilities.

The first scenario is mitigated by the fact that an attacker must have a role with the 'manage PIFR environments' administrative permission.

The second scenario is mitigated by the fact that an attacker must be able to initiate testing of a patch specially crafted to exploit the vulnerability on the PIFR testing environment, have the testing execute successfully on a PIFR client, and have the client provide the testing results back to the PIFR server component.

As one common purpose of this module is to provide validation and testing of user-supplied patches, users of the PIFR module should always consider the 'PIFR client' component of this module as insecure and untrusted, by design. The 'PIFR client' component should always be maintained in a separate network environment, isolated from the 'PIFR server' component or other critical infrastructure.

There have been no known exploits of this vulnerability observed or reported on any servers running the PIFR module, including those within Drupal.org's automated testing environment.
