CVE-2018-10167 — Tp-Link Eap Controller security vulnerability

High CVSS 7.5

The web application backup file in the TP-Link EAP Controller and Omada Controller versions 2.5.4_Windows/2.6.0_Windows is encrypted with a hard-coded cryptographic key, so anyone who knows that key and the algorithm can decrypt it. A low-privilege user could decrypt and modify the backup file in order to elevate their privileges. This is fixed in version 2.6.1_Windows.

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.
