CVE-2018-20162

Estado: ModificadaCrítica (9.9)—💥 PoC

Digi TransPort LR54 4.4.0.26 and possible earlier devices have Improper Input Validation that allows users with 'super' CLI access privileges to bypass a restricted shell and execute arbitrary commands as root.

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.
