What is CVE-2026-34474?

The ZTE ZXHN H298A (version 1.1) and ZXHN H108N (version 2.6) have a vulnerability that can lead to sensitive data exposure. An attacker can exploit this issue by sending a crafted request to the router's web interface, potentially revealing sensitive information such as the administrator password and WLAN Pre-Shared Key (PSK). This exposure poses serious security risks, including the possibility of authentication bypass and network compromise. Additionally, certain firmware versions might leak partial identifiers like serial numbers, ESSID, and MAC addresses, further amplifying the vulnerability.

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.
