Estado: AnalizadaMedia (5.4)—💥 Exploit

A Stored Cross-site scripting (XSS) vulnerability in /main.html Wifi Settings in Tenda AC5 AC1200 version V15.03.06.47_multi allows remote attackers to inject arbitrary web script or HTML via the Wifi Name parameter.

CVSS

Probabilidad de explotación (EPSS)

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).

💥 Exploits públicos

Hay código de explotación o plantillas de detección públicos. No es lo mismo que explotación activa confirmada (KEV), pero aumenta el riesgo: parchee con prioridad.
