CVE-2020-25223

Estado: AnalizadaCrítica (9.8)⚠ Explotación activa💥 Exploit

A remote code execution vulnerability exists in the WebAdmin of Sophos SG UTM before v9.705 MR5, v9.607 MR7, and v9.511 MR11

CVSS

Versión: 3.1
Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Puntuación base: 9.8

Probabilidad de explotación (EPSS)

Probabilidad de explotación en los próximos 30 días: 97%
Percentil entre todas las CVEs puntuadas: 100
Fecha de la puntuación: 3/10/2026

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: 25/3/2022
Plazo de remediación: 15/4/2022
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.

Módulo de Metasploit (exploit fiable y al alcance de cualquiera) · Sophos UTM WebAdmin SID Command Injection
Plantilla de Nuclei (detección automática y masiva) · Sophos UTM Preauth - Remote Code Execution
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.

🎯 Técnicas ATT&CK

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