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.
A cross-site scripting (XSS) vulnerability in the View Filters page (view_filters_page.php) and Edit Filter page (manage_filter_edit_page.php) in MantisBT 2.1.0 through 2.17.0 allows remote attackers to inject arbitrary code (if CSP settings permit it) through a crafted PATH_INFO. NOTE: this vulnerability exists because of an incomplete fix for CVE-2018-13055.
A cross-site scripting (XSS) vulnerability in the Manage Filters page (manage_filter_page.php) in MantisBT 2.1.0 through 2.17.1 allows remote attackers (if access rights permit it) to inject arbitrary code (if CSP settings permit it) through a crafted project name.
A cross-site scripting (XSS) vulnerability in the Edit Filter page (manage_filter_edit page.php) in MantisBT 2.1.0 through 2.17.1 allows remote attackers (if access rights permit it) to inject arbitrary code (if CSP settings permit it) through a crafted project name.
A cross-site scripting (XSS) vulnerability in the View Filters page (view_filters_page.php) in MantisBT 2.1.0 through 2.15.0 allows remote attackers to inject arbitrary code (if CSP settings permit it) through a crafted PATH_INFO.
An issue was discovered in manage_filter_edit_page.php in MantisBT 2.x through 2.15.0. A cross-site scripting (XSS) vulnerability in the Edit Filter page allows execution of arbitrary code (if CSP settings permit it) when displaying a filter with a crafted name (e.g., 'foobar" onclick="alert(1)').
