Description

In Apache Brooklyn before 0.10.0, the REST server is vulnerable to cross-site scripting where one authenticated user can cause scripts to run in the browser of another user authorized to access the first user's resources. This is due to improper escaping of server-side content. There is known to be a proof-of-concept exploit using this vulnerability.

Detection & mitigation playbook

Open-source dependency

  1. Detect

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

  2. Fix

    Update org.apache.brooklyn:brooklyn to 0.10.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2017-3165 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.
