   * Advisory ID: DRUPAL-SA-CONTRIB-2014-023
   * Project: Project Issue File Review [1] (third-party module)
   * Version: 6.x
   * Date: 2014-February-26
   * Security risk: Moderately critical [2]
   * 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.


-------- CVE IDENTIFIER(S) ISSUED
--------------------------------------------

   * /A CVE identifier [3] will be requested, and added upon issuance, in

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

   * Project_Issue_File_Review 6.x-2.x versions prior to 6.x-2.17.
