Detection & mitigation playbook

Vendor / appliance

  1. Detect

    Inventory every pandorafms pandora fms deployment and check each version against the affected-products list above.

  2. Remediation status

    No patch has shipped for CVE-2020-13851 yet — track the pandorafms pandora fms advisory for a fixed release and apply the workarounds below in the meantime.

  3. Mitigate without a patch

    Stop passing untrusted input into the interpreter or shell: call the affected binary with an argument array rather than a composed command string, reject anything outside a strict allowlist of expected values, and run the component under an account that cannot reach beyond the work it legitimately does. Alongside that, restrict the management interface to trusted networks and apply the vendor's recommended configuration mitigations.
