Description

Sensitive data exposure leading to admin/WLAN credential leak in ZTE ZXHN H298A 1.1 and H108N 2.6. A crafted request to the router web interface can expose sensitive device and account information. In affected builds, the response may include the administrator password and WLAN PSK, enabling authentication bypass and network compromise. Some firmware versions may expose only partial identifiers (e.g., serial number, ESSID, MAC addresses).
