CVE-2019-19411 — Huawei Usg9500 Firmware security vulnerability

Medium CVSS 4.3

USG9500 with versions of V500R001C30SPC100, V500R001C30SPC200, V500R001C30SPC600, V500R001C60SPC500, V500R005C00SPC100, V500R005C00SPC200 have an information leakage vulnerability. Due to improper processing of the initialization vector used in a specific encryption algorithm, an attacker who gains access to this cryptographic primitive may exploit this vulnerability to cause the value of the confidentiality associated with its use to be diminished.

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.
