MantisBT Vulnerable to Stored HTML Injection in Tag Delete Confirmation
Improper escaping of Tag name when deleting it in tag_delete.php allows an attacker to inject HTML and, if CSP settings permit, achieve execution of arbitrary JavaScript. ### Impact Cross-site scripting (XSS). ### Patches 80990f43153167c73f11eb4b2bc7108d0c3d6b46 ### Workarounds * Revert commit d6890320752ecf37bd74d11fe14fe7dc12335be9 * Manually edit language files to remove the sprintf placeholder `%1$s` from *$s_tag_delete_message* string, for example with `sed -r -i '/tag_delete_message/s/.%1\$s.//' -- lang/` ### Credits MantisBT hanks Vishal Shukla for discovering and responsibly reporting the issue.
