CVE-2024-31853

Estado: AnalizadaAlta (7.7)—

A vulnerability has been identified in SICAM TOOLBOX II (All versions < V07.11). During establishment of a https connection to the TLS server of a managed device, the affected application doesn't check the extended key usage attribute of that device's certificate. This could allow an attacker to execute an on-path network (MitM) attack.

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.

SICAM TOOLBOX II valida certificados TLS incompleta (CWE-295), permitiendo MitM con UI:P. Atacante intercepta conexión HTTPS para leer datos de dispositivo gestionado.

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.
