CVE-2018-15781

Estado: ModificadaAlta (8)—

El codificador de contraseñas Dell Wyse en ThinLinux2, en versiones anteriores a la 2.1.0.01, contiene una vulnerabilidad de clave criptográfica embebida. Un atacante remoto no autenticado podría emplear ingeniería inversa en el sistema criptográfico empleado en el codificador de contraseñas Dell Wyse para descubrir la clave privada embebida y descifrar el texto cifrado almacenado de forma local.

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).
