CVE-2019-5291 — Some Huawei products have an insufficient verification of data authenticity vulnerability

Medium CVSS 5.9

Some Huawei products have an insufficient verification of data authenticity vulnerability. A remote, unauthenticated attacker has to intercept specific packets between two devices, modify the packets, and send the modified packets to the peer device. Due to insufficient verification of some fields in the packets, an attacker may exploit the vulnerability to cause the target device to be abnormal.

Matched remediation archetype

Supply-chain, dependency, build, and update integrity

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

Check exposure

  • Trace affected packages, source archives, build actions, plugins, installers, and updates from declared source to deployed artifact.
  • Confirm provenance, signatures or digests, namespace ownership, lockfile resolution, registry configuration, and build-runner trust boundaries.
  • Inventory direct, transitive, vendored, generated, and bundled copies across releases and distribution channels.

Remediate safely

  • Move to a maintained trusted artifact or remove the dependency; pin immutable identities and verify provenance and integrity before use.
  • Regenerate lockfiles and artifacts in a clean isolated build, minimize build credentials and network access, and produce an updated software bill of materials.
  • Require reviewed update policy, protected publishing, and reproducible or independently attestable builds where supported.
