PatchTheCVECVE-2026-34474: Sensitive data exposure leading to admin/WLAN credential leak in ZTE ZXHN H298A 1.1 and H108N 2.6
CVE-2026-34474 is a high-severity flaw (CVSS 7.5) affecting affected software. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
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).
