CVE-2020-1206
Estado: ModificadaAlta (7.5)—💥 PoC
Se presenta una vulnerabilidad de divulgación de información en la manera en que el protocolo Microsoft Server Message Block versión 3.1.1 (SMBv3) maneja determinadas peticiones, también se conoce como "Windows SMBv3 Client/Server Information Disclosure Vulnerability"
CVSS
- Versión: 3.1
- Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N
- Puntuación base: 7.5
Probabilidad de explotación (EPSS)
- Probabilidad de explotación en los próximos 30 días: 10%
- Percentil entre todas las CVEs puntuadas: 96
- Fecha de la puntuación: 17/10/2026
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.
- Prueba de concepto en GitHub (no verificada) · Lista de pruebas de concepto en GitHub
⚠️ Las pruebas de concepto de GitHub no están verificadas: algunas son falsas o contienen malware. No las ejecute nunca fuera de un laboratorio aislado.
