Description

chef-server-api/app/controllers/users.rb in the API in Chef before 0.9.0 does not require administrative privileges for the create, destroy, and update methods, which allows remote authenticated users to manage user accounts via requests to the /users URI.

Detection & mitigation playbook

Open-source dependency
  1. Detect

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

  2. Fix

    Update chef to 0.9.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2010-5142 is resolved across your whole dependency graph.

  3. Workarounds

    If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.

  4. How O3 protects you

    O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like CVE-2010-5142 can be triaged on real exposure rather than presence alone.

Tailored to CVE-2010-5142. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
