CVE-2021-36717

Estado: ModificadaAlta (7.5)—

La versión 9.21 de Synerion TimeNet contiene una vulnerabilidad de cruce de directorios en la que, en el parámetro "Name", el atacante puede volver al directorio raíz y abrir el archivo del host. Esto podría dar al atacante la capacidad de ver archivos restringidos, lo que podría proporcionar al atacante más información necesaria para comprometer aún más el sistema

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).
