CVE-2026-34474
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).
CVSS
- Versión: 3.1
- Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N
- Puntuación base: 7.5
Probabilidad de explotación (EPSS)
- Probabilidad de explotación en los próximos 30 días: 2.08%
- Percentil entre todas las CVEs puntuadas: 81
- Fecha de la puntuación: 5/10/2026
EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).
