Detection & mitigation playbook

Vendor / appliance

  1. Detect

    Inventory every dell secure connect gateway deployment and check each version against the affected-products list above.

  2. Fix

    Apply the dell secure connect gateway security patch or hotfix for CVE-2026-78484 on the affected version, following the vendor advisory for your exact build.

  3. Workarounds

    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.
