CVE-2026-76482
As part of Cisco's ongoing commitment to proactive security and product quality, the engineering team for Cisco License On-Prem, formerly Cisco Smart Software Manager On-Prem (SSM On-Prem), has conducted a comprehensive internal security review. This review resulted in software hardening releases that address multiple internally discovered vulnerabilities.
The vulnerabilities tracked by CVE-2026-76482 are related to issues with improper input verification that are grouped under the Common Weakness Enumeration (CWE) Pillar CWE-347.
CVSS
- Versión: 3.1
- Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H
- Puntuación base: 10
Probabilidad de explotación (EPSS)
FIRST aún no ha puntuado esta CVE (habitual en CVEs muy recientes o rechazadas).
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
T1190Exploit Public-Facing Applicationinitial access85 %
Vector CVSS N/A/N indica explotación remota sin autenticación (T1190). CWE-347 (improper verification) sugiere manipulación de certificados/firmas (T1553.006) e integridad de datos (T1565.002). Alcance changed y confidencialidad/integridad altas confirman criticidad.
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.
