Description

Salt (aka SaltStack) 0.15.0 through 0.17.0 allows remote authenticated users who are using external authentication or client ACL to execute restricted routines by embedding the routine in another routine.

Detection & mitigation playbook

Open-source dependency

  1. Detect

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

  2. Fix

    Update salt to 0.17.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2013-4435 is resolved across your whole dependency graph.

  3. Workarounds

    Put an independent control in front of the weakness: restrict the affected endpoint or interface to trusted networks, require an additional authentication factor or proxy-level check, and invalidate existing sessions and credentials in case the flaw has already been used.
