CVE-2018-17873

Estado: ModificadaAlta (8.8)—💥 PoC

An incorrect access control vulnerability in the FTP configuration of WiFiRanger devices with firmware version 7.0.8rc3 and earlier allows an attacker with adjacent network access to read the SSH Private Key and log in to the root account.

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.
