What is CVE-2026-34472?

The ZTE ZXHN H188A router exhibits a vulnerability in its wizard interface, allowing unauthenticated users on the local network to access sensitive credentials. This includes retrieval of the default administrator password, WLAN Pre-Shared Key (PSK), and PPPoE credentials from the router's web management interface. In certain instances, unauthorized changes to configurations can also be executed without authentication, posing a significant security risk to users and their networks.

Exploit Proof of Concept (PoC)

PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
