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.
MantisBT 1.2.x before 1.2.2 insecurely handles attachments and MIME types. Arbitrary inline attachment rendering could lead to cross-domain scripting or other browser attacks.
A cross-site scripting (XSS) vulnerability in MantisBT 1.2.14 allows remote attackers to inject arbitrary web script or HTML via a version, related to deleting a version.
A cross-site scripting (XSS) vulnerability in the configuration report page (adm_config_report.php) in MantisBT 1.2.13 allows remote authenticated users to inject arbitrary web script or HTML via a project name.
A cross-site scripting (XSS) vulnerability in the configuration report page (adm_config_report.php) in MantisBT 1.2.0rc1 before 1.2.14 allows remote authenticated users to inject arbitrary web script or HTML via a complex value.
The Timeline feature in my_view_page.php in MantisBT through 2.21.1 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 for any user having visibility to the issue, whenever My View Page is displayed.
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.
