CVE-2017-7241 Explained : Impact and Mitigation

A vulnerability known as cross-site scripting (XSS) has been identified in the MantisBT Move Attachments page (move_attachments_page.php), which is part of the admin tools. This vulnerability allows attackers to inject arbitrary code into the system by manipulating the 'type' parameter, provided that the Content Security Protection (CSP) settings permit such actions. To address this issue, the developers have released versions 1.3.9, 2.1.3, and 2.2.3, which include the necessary fixes. It is important to note that this vulnerability cannot be exploited if the admin tools directory is removed, as suggested in the "Post-installation and upgrade tasks" section of the MantisBT Admin Guide. A reminder to remove the admin tools directory will also be displayed on the login page.
