An XSS issue was discovered in manage_user_page.php in MantisBT 2.x before 2.5.2. The 'filter' field is not sanitized before being rendered in the Manage User page, allowing remote attackers to execute arbitrary JavaScript code if CSP is disabled.

A cross-site scripting (XSS) vulnerability in the MantisBT Move Attachments page (move_attachments_page.php, part of admin tools) allows remote attackers to inject arbitrary code through a crafted 'type' parameter, if Content Security Protection (CSP) settings allows it. This is fixed in 1.3.9, 2.1.3, and 2.2.3. Note that this vulnerability is not exploitable if the admin tools directory is removed, as recommended in the "Post-installation and upgrade tasks" of the MantisBT Admin Guide. A reminder to do so is also displayed on the login page.

A cross-site scripting (XSS) vulnerability in the MantisBT Configuration Report page (adm_config_report.php) allows remote attackers to inject arbitrary code (if CSP settings permit it) through a crafted 'config_option' parameter. This is fixed in 1.3.9, 2.1.3, and 2.2.3.

A cross-site scripting (XSS) vulnerability in the MantisBT Configuration Report page (adm_config_report.php) allows remote attackers to inject arbitrary code through a crafted 'action' parameter. This is fixed in 1.3.8, 2.1.2, and 2.2.2.
