CVE-2022-41540 — The web app client of TP-Link AX10v1 V1_211117 uses hard-coded cryptographic keys when communicating with the router

Medium CVSS 5.9

The web app client of TP-Link AX10v1 V1_211117 uses hard-coded cryptographic keys when communicating with the router. Attackers who are able to intercept the communications between the web client and router through a man-in-the-middle attack can then obtain the sequence key via a brute-force attack, and access sensitive information.

Matched remediation archetype

Authentication bypass and missing authentication

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Map every affected endpoint and protocol path, including alternate ports, legacy routes, recovery flows, service accounts, and machine-to-machine access.
  • Confirm which deployments enable the affected authentication mode and whether the interface is reachable from untrusted networks.
  • Review session, token, credential, and proxy trust configuration without attempting account takeover.

Remediate safely

  • Apply the supported fix and centralize fail-closed authentication before protected request handling.
  • Remove default or embedded credentials, rotate affected secrets and sessions, and bind authentication decisions to the intended audience and channel.
  • Add negative tests for alternate routes, malformed or absent credentials, recovery flows, and proxy-derived identity.
