CVE-2017-20238

Estado: Pendiente de análisisAlta (7.1)—

Hirschmann Industrial HiVision versions 06.0.00 and 07.0.00 prior to 06.0.06 and 07.0.01 contains an improper authorization vulnerability that allows read-only users to gain write access to managed devices by bypassing access control mechanisms. Attackers can exploit alternative interfaces such as the web interface or SNMP browser to modify device configurations despite having restricted permissions.

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.

Vulnerabilidad de autorización (CWE-285) en servicio remoto (AV:N, PR:L) que permite a usuarios de solo lectura modificar configuraciones de dispositivos gestionados mediante interfaces alternativas como SNMP, escalando privilegios de escritura.

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.
