Some vulnerabilities have been reported in the Project module for Drupal, which can be exploited by malicious people to conduct cross-site scripting attacks and malicious users to compromise a vulnerable system.

1) The application fails to validate the types of uploaded files associated with project releases. This can be exploited to upload files with arbitrary extensions (e.g. pht, php3, etc.) and execute arbitrary PHP code on the server.

Successful exploitation of this vulnerability requires a certain server configuration (e.g. an Apache server with the "mod_mime" module installed) and requires the "maintain projects" permission.

NOTE: Projects associated with a CVS repository using the CVS integration module are not affected.

2) Input passed to unspecified parameters is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in the context of an affected site.

These vulnerabilities are reported in versions prior to 5.x-1.3.

Solution
Update to version 5.x-1.3.
