MantisBT XSS allows unsanitized input via admin/install.php

Check your stack

The advisory, in context

An XSS issue was discovered in admin/install.php in MantisBT before 1.3.12 and 2.x before 2.5.2. Some variables under user control in the MantisBT installation script are not properly sanitized before being output, allowing remote attackers to inject arbitrary JavaScript code, as demonstrated by the $f_database, $f_db_username, and $f_admin_username variables. This is mitigated by the fact that the admin/ folder should be deleted after installation, and also prevented by CSP.

Affected packages

Start with the recorded fix for your release branch. Check your installed version and test compatibility before upgrading. Fixing this advisory does not rule out other vulnerabilities in the release.
