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.
