CVE-2019-5300 — Huawei Ar1200 Firmware security vulnerability

Medium CVSS 6.7

There is a digital signature verification bypass vulnerability in AR1200, AR1200-S, AR150, AR160, AR200, AR2200, AR2200-S, AR3200, SRG1300, SRG2300 and SRG3300 Huawei routers. The vulnerability is due to the affected software improperly verifying digital signatures for the software image in the affected device. A local attacker with high privilege may exploit the vulnerability to bypass integrity checks for software images and install a malicious software image on the affected 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.
