CVE-2020-11492

Estado: ModificadaAlta (7.8)—💥 PoC

An issue was discovered in Docker Desktop through 2.2.0.5 on Windows. If a local attacker sets up their own named pipe prior to starting Docker with the same name, this attacker can intercept a connection attempt from Docker Service (which runs as SYSTEM), and then impersonate their privileges.

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.
