CVE-2020-1350

Estado: AnalizadaCrítica (10)⚠ Explotación activa💥 PoC

Se presenta una vulnerabilidad de ejecución de código remota en los servidores de Windows Domain Name System cuando presentan un fallo al manejar apropiadamente las peticiones, también se conoce como "Windows DNS Server Remote Code Execution Vulnerability"

CVSS

Versión: 3.1
Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H
Puntuación base: 10

Probabilidad de explotación (EPSS)

Probabilidad de explotación en los próximos 30 días: 97%
Percentil entre todas las CVEs puntuadas: 100
Fecha de la puntuación: 8/10/2026

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).

CISA KEV — explotada activamente

Añadida al catálogo: 3/11/2021
Plazo de remediación: 3/5/2022
Uso conocido en ransomware: Unknown

💥 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.

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

ExplotaciónT1190 Exploit Public-Facing Applicationinitial access95 %
Impacto principalT1059.001 PowerShellexecution90 %
Impacto secundarioT1499.004 Application or System Exploitationimpact75 %

Vector AV:N/PR:N sin interacción indica T1190. El servidor DNS remoto procesa solicitudes malformadas causando RCE. Impactos: ejecución de código (T1059.001), DoS por corrupción DNS (T1499.004), y potencial acceso administrativo (T1078.002) en infraestructura crítica.

Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.
