Description

A cross-site scripting (XSS) vulnerability in the MantisBT (2.3.x before 2.3.2) Timeline include page, used in My View (my_view_page.php) and User Information (view_user_page.php) pages, allows remote attackers to inject arbitrary code (if CSP settings permit it) through crafted PATH_INFO in a URL, due to use of unsanitized $_SERVER['PHP_SELF'] to generate URLs.

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for mantisbt/mantisbt, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update mantisbt/mantisbt to 2.3.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2017-7897 is resolved across your whole dependency graph.

  3. Workarounds

    Escape or sanitise the affected output on the server side rather than relying on client-side filtering, and add a Content-Security-Policy that blocks inline script execution so injected markup cannot run even if it reaches the page.
