CVE-2020-8958

Estado: ModificadaAlta (7.2)—💥 PoC

Los dispositivos Guangzhou 1GE ONU V2801RW versiones 1.9.1-181203 hasta 2.9.0-181024 y V2804RGW versiones 1.9.1-181203 hasta 2.9.0-181024, permiten a atacantes remotos ejecutar comandos arbitrarios de Sistema Operativo por medio de metacaracteres de shell en el campo Dest IP Address del archivo boaform/admin/formPing

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.

⚠️ Las pruebas de concepto de GitHub no están verificadas: algunas son falsas o contienen malware. No las ejecute nunca fuera de un laboratorio aislado.
