CVE-2026-34472 — Zte Zxhn H188A Firmware security vulnerability

High CVSS 7.1

Unauthenticated credential disclosure in the wizard interface in ZTE ZXHN H188A V6.0.10P2_TE and V6.0.10P3N3_TE allows unauthenticated attackers on the local network to retrieve sensitive credentials from the router's web management interface, including the default administrator password, WLAN PSK, and PPPoE credentials. In some observed cases, configuration changes may also be performed without authentication.

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.
