CVE-2026-40677

Estado: Pendiente de análisisAlta (7.7)—

The use of insecure HTTP transport within AMD optional tools could allow an attacker to conduct a man-in-the-middle attack, potentially leading to arbitrary code execution.

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.

Transporte HTTP inseguro con interacción del usuario (UI:P) permite MITM para ejecutar código arbitrario. Impacto: ejecución de comandos (VC:H) y posicionamiento como adversario en el medio.

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.
