Description

The SlingRequestDispatcher doesn't correctly implement the RequestDispatcher API resulting in a generic type of include-based cross-site scripting issues on the Apache Sling level. The vulnerability is exploitable by an attacker that is able to include a resource with specific content-type and control the include path (i.e. writing content). The impact of a successful attack is privilege escalation to administrative power.

Please update to Apache Sling Engine version 2.14.0 or newer and enable the "Check Content-Type overrides" configuration option.

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.sling:org.apache.sling.engine, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update org.apache.sling:org.apache.sling.engine to 2.14.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2022-45064 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.
