Mantis Bug Tracker 1.2.3 – ‘db_type’ Cross-Site Scripting / Full Path Disclosure

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

Vendor: MantisBT Group

Product web page: http://www.mantisbt.org

Version affected: <1.2.4

Summary: 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).

Desc: 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.

Tested on: Microsoft Windows XP Professional SP3 (English)

Debian GNU/Linux (squeeze)

Apache 2.2.14 (Win32)

MySQL 5.1.41

PHP 5.3.1
