CVE-2026-76676
Buffer overflow vulnerabilities exist in the underlying operating system of EdgeConnect SD-WAN Gateways that could allow an unauthenticated adjacent attacker to execute arbitrary code if certain preconditions outside of the attacker's control are met. Successful exploitation could allow an attacker to execute arbitrary code as a privileged user on the underlying operating system leading to complete system compromise.
CVSS
- Versión: 3.1
- Vector: CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
- Puntuación base: 8.8
Probabilidad de explotación (EPSS)
- Probabilidad de explotación en los próximos 30 días: 0.35%
- Percentil entre todas las CVEs puntuadas: 26
- Fecha de la puntuación: 6/10/2026
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).
🎯 Técnicas ATT&CK

- Explotación
T1210Exploitation of Remote Serviceslateral movement85 % - Impacto principal
T1059Command and Scripting Interpreterexecution90 % - Impacto secundario
T1068Exploitation for Privilege Escalationprivilege escalation80 %
Buffer overflow en red adyacente (AV:A) sin autenticación; ejecución de código arbitrario como usuario privilegiado implica T1059 e T1068 por escalada de privilegios.
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.
