MantisBT <=1.2.3 (db_type) Cross-Site Scripting & Path Disclosure Vulnerability

Title: MantisBT <=1.2.3 (db_type) Cross-Site Scripting & Path Disclosure Vulnerability
Advisory ID: ZSL-2010-4983
Type: Remote
Impact: Cross-Site Scripting, Exposure of System Information
Risk: (3/5)
Release Date: 15.12.2010
MantisBT is a free popular web-based bugtracking system. It is written in the PHP scripting language and works with MySQL, MS SQL, and PostgreSQL databases and a webserver. MantisBT has been installed on Windows, Linux, Mac OS, OS/2, and others. Almost any web browser should be able to function as a client. It is released under the terms of the GNU General Public License (GPL).
Mantis Bug Tracker suffers from a cross-site scripting and a path disclosure vulnerability. The XSS issue is triggered when input passed via the "db_type" parameter to the admin/upgrade_unattended.php script 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 context of an affected site. The PD weakness is caused due to the application displaying the full installation path in an error report, when supplying an invalid "db_type" parameter to the admin/upgrade_unattended.php script.
