CVE-2019-6972 — An issue was discovered on TP-Link TL-WR1043ND V2 devices

High CVSS 7.5

An issue was discovered on TP-Link TL-WR1043ND V2 devices. The credentials can be easily decoded and cracked by brute-force, WordList, or Rainbow Table attacks. Specifically, credentials in the "Authorization" cookie are encoded with URL encoding and base64, leading to easy decoding. Also, the username is cleartext, and the password is hashed with the MD5 algorithm (after decoding of the URL encoded string with base64).

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.
