CVE-2026-73710

Estado: AnalizadaAlta (8.2)—

Vulnerabilities in an API endpoint of HPE Networking Fabric Composer could allow an unauthenticated remote attacker to conduct a denial of service attack. Successful exploitation could allow an attacker to make limited unauthorized modifications to the underlying operating system and disrupt the availability of the affected system, requiring manual intervention to restore functionality.

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.

Vector CVSS AV:N/PR:N/UI:N sin autenticación → T1190. DoS remoto + modificaciones no autorizadas del SO según descripción. T1499.004 (application exhaustion) por ataque DoS contra endpoint API; T1565.001 por cambios limitados en SO.

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.
