Description

Untrusted search path vulnerability in Puppet Enterprise 2.8 before 2.8.7, Puppet before 2.7.26 and 3.x before 3.6.2, Facter 1.6.x and 2.x before 2.0.2, Hiera before 1.3.4, and Mcollective before 2.5.2, when running with Ruby 1.9.1 or earlier, allows local users to gain privileges via a Trojan horse file in the current working directory, as demonstrated using (1) rubygems/defaults/operating_system.rb, (2) Win32API.rb, (3) Win32API.so, (4) safe_yaml.rb, (5) safe_yaml/deep.rb, or (6) safe_yaml/deep.so; or (7) operatingsystem.rb, (8) operatingsystem.so, (9) osfamily.rb, or (10) osfamily.so in puppet/confine.

Detection & mitigation playbook

Open-source dependency
  1. Detect

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

  2. Fix

    Update facter to 1.7.6 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2014-3248 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-2014-3248 can be triaged on real exposure rather than presence alone.

Tailored to CVE-2014-3248. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
