CVE-2019-6569 — The monitor barrier of the affected products insufficiently blocks data from being forwarded over the mirror port into the mirrored network

Critical CVSS 9.1

The monitor barrier of the affected products insufficiently blocks data from being forwarded over the mirror port into the mirrored network. An attacker could use this behavior to transmit malicious packets to systems in the mirrored network, possibly influencing their configuration and runtime behavior.

Matched remediation archetype

General vulnerability remediation

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Confirm the affected component, deployment paths, reachable interfaces, and enabled features from inventories and configuration, without probing production destructively.
  • Compare the advisory's affected conditions with the repository lockfiles, build manifests, artifacts, and runtime inventory.
  • Identify data sensitivity, trust boundaries, and privilege level for every confirmed affected deployment.

Remediate safely

  • Apply a vendor-supported fix or remove the affected component or feature; record the selected change and its source in the repository.
  • Update direct and transitive dependency locks, generated artifacts, deployment manifests, and asset inventories together.
  • Add a regression test for the documented unsafe condition using inert inputs and preserve rollback instructions.
