Description

Multiple Cross-Site Scripting (XSS) issues were discovered in INTER-Mediator 5.5. The vulnerabilities exist due to insufficient filtration of user-supplied data (c and cred) passed to the "INTER-Mediator-master/Auth_Support/PasswordReset/resetpassword.php" URL. An attacker could execute arbitrary HTML and script code in a browser in the context of the vulnerable website.

Detection & mitigation playbook

Open-source dependency

  1. Detect

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

  2. Fix

    Update inter-mediator/inter-mediator to 5.6 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2017-6484 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.
