An XSS issue was discovered in MantisBT before 2.24.2. Improper escaping on view_all_bug_page.php allows a remote attacker to inject arbitrary HTML into the page by saving it into a text Custom Field, leading to possible code execution in the browser of any user subsequently viewing the issue (if CSP settings allow it).
The proj_doc_edit_page.php Project Documentation feature in MantisBT before 2.21.3 has a stored cross-site scripting (XSS) vulnerability, allowing execution of arbitrary code (if CSP settings permit it) after uploading an attachment with a crafted filename. The code is executed when editing the document's page.
view_all_bug_page.php in MantisBT 2.10.0-development before 2018-02-02 allows remote attackers to discover the full path via an invalid filter parameter, related to a filter_ensure_valid_filter call in current_user_api.php.
A cross-site scripting (XSS) vulnerability in MantisBT before 2.1.1 allows remote attackers to inject arbitrary HTML or JavaScript (if MantisBT's CSP settings permit it) by modifying 'window_title' in the application configuration. This requires privileged access to MantisBT configuration management pages (i.e., administrator access rights) or altering the system configuration file (config_inc.php).
A cross-site scripting (XSS) vulnerability in view_filters_page.php in MantisBT before 2.2.1 allows remote attackers to inject arbitrary JavaScript via the 'view_type' parameter.
