CVE-2019-15653 — Comba AP2600-I devices through A02,0202N00PD2 are prone to password disclosure via an insecure authentication mechanism

High CVSS 7.5

Comba AP2600-I devices through A02,0202N00PD2 are prone to password disclosure via an insecure authentication mechanism. The HTML source code of the login page contains values that allow obtaining the username and password. The username are password values are a double md5 of the plaintext real value, i.e., md5(md5(value)).

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.
