A successful exploit could allow the attacker to read arbitrary files from a restricted container of the affected device.

Detalles técnicos trazas, registros y código del informe original
A vulnerability in Cisco Catalyst Center could allow an unauthenticated, remote attacker to read arbitrary files from a restricted container. 

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 indica explotación remota sin autenticación (T1190). CWE-22 (path traversal) y descripción explícita de 'read arbitrary files' confirman acceso a datos en contenedor (T1005).

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.
