Estado: ModificadaAlta (8.8)—💥 Exploit

The Alcatel Lucent I-240W-Q GPON ONT using firmware version 3FE54567BOZJ19 is vulnerable to a stack buffer overflow via crafted HTTP POST request sent by a remote, authenticated attacker to /GponForm/usb_Form?script/. An attacker can leverage this vulnerability to potentially execute arbitrary code.

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.
