CVE intelligence and bounded remediation

CVE-2016-5638 — There are few web pages associated with the genie app on the Netgear WNDR4500 running firmware version V1.0.1.40_1.0.6877

High CVSS 7.5

There are few web pages associated with the genie app on the Netgear WNDR4500 running firmware version V1.0.1.40_1.0.6877. Genie app adds some capabilities over the Web GUI and can be accessed even when you are away from home. A remote attacker can access genie_ping.htm or genie_ping2.htm or genie_ping3.htm page without authentication. Once accessed, the page will be redirected to the aCongratulations2.htma page, which reveals some sensitive information such as 2.4GHz & 5GHz Wireless Network Name (SSID) and Network Key (Password) in clear text.

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.
