CVE-2026-3820

Estado: Pendiente de análisisAlta (7.2)—

There is a vulnerability in the Supermicro BMC SMTP service at Supermicro AS-2115HS-TNR.  An attacker may obtain administrator privileges and inject specially crafted characters into the SMTP service configuration. This may cause the underlying system to execute unintended commands during process invocation.

Potential impact includes denial-of-service attacks, arbitrary code execution, or permanent compromise of the controller.

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).

🎯 Técnicas ATT&CK

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

AV:N/PR:H indica explotación de servicio remoto (SMTP) con privilegios previos (T1210). CWE-78 y 'execute unintended commands' → T1059. 'denial-of-service attacks' → T1499.004.

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.
