CVE intelligence and bounded remediation

CVE-2017-15341 — Huawei AR3200 V200R008C20, V200R008C30, TE40 V600R006C00, TE50 V600R006C00, TE60 V600R006C00 have a denial of service vulnerability

High CVSS 7.5

Huawei AR3200 V200R008C20, V200R008C30, TE40 V600R006C00, TE50 V600R006C00, TE60 V600R006C00 have a denial of service vulnerability. The software decodes X.509 certificate in an improper way. A remote unauthenticated attacker could send a crafted X.509 certificate to the device. Successful exploit could result in a denial of service on the device.

Matched remediation archetype

Cryptography, certificate, signature, and channel validation

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

Check exposure

  • Inventory affected algorithms, key uses, trust stores, certificate validation settings, random sources, and plaintext channels across clients and services.
  • Determine which secrets, identities, signatures, or data protections depend on the affected primitive or validation path.
  • Check debug, compatibility, fallback, and hostname or audience override settings in build and runtime configuration.

Remediate safely

  • Use a maintained platform cryptographic API with approved algorithms, modes, parameters, randomness, and full peer identity validation.
  • Remove insecure fallback and validation bypasses; separate keys by purpose and load them from managed secret storage.
  • Plan rotation or reissuance for affected keys, certificates, tokens, hashes, or ciphertext and document compatibility sequencing.
