MantisBT 2.28.3 and earlier contains six reflected XSS injection points in
/admin/install.php. User-supplied parameters are echoed into HTML without escaping via an unescaped printf format string. No authentication is required.A Content Security Policy (script-src 'self') prevents inline JavaScript execution, but the CSP is missing a form-action directive, allowing exploitation via credential-phishing form injection and open redirects.
Impact
- Credential phishing: Attacker crafts a URL that renders a fake login form on the real MantisBT admin page. Admin credentials are submitted to an attacker-controlled server.
- Open redirect: Victim is silently redirected to a phishing or malware site.
- UI manipulation: CSS injection can hide legitimate page content and overlay attacker-controlled HTML, enabling social engineering.
Patches
Workarounds

/admin directory, as [recommended in the Admin Guide](https://mantisbt.org/docs/master/en-US/Admin Guide/html-desktop/#admin.install.postcommon)Resources
