CVE-2019-13604 — There is a short key vulnerability in HID Global DigitalPersona (formerly Crossmatch) U.are.U 4500 Fingerprint Reader v24

Medium CVSS 5.9

There is a short key vulnerability in HID Global DigitalPersona (formerly Crossmatch) U.are.U 4500 Fingerprint Reader v24. The key for obfuscating the fingerprint image is vulnerable to brute-force attacks. This allows an attacker to recover the key and decrypt that image using the key. Successful exploitation causes a sensitive biometric information leak.

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.
