CVE-2026-76726

Estado: Pendiente de análisisAlta (8.1)—

An authentication bypass vulnerability in the API endpoint of HPE Networking Instant ON could allow an unauthenticated remote attacker to bypass network access controls if certain preconditions outside of the attacker's control are met. Successful exploitation could allow an attacker to obtain unauthorized access to restricted networks.

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.

Explotación remota sin autenticación en API (AV:N, PR:N) de producto de networking; acceso a redes restringidas implica obtención de credenciales/sesiones (T1078) y potencial uso como proxy de red (T1090).

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.
