CVE-2019-19298

Estado: ModificadaAlta (7.5)—

Se ha identificado una vulnerabilidad en SiNVR/SiVMS Video Server (Todas las versiones anteriores a V5.0.2). El servicio de streaming (puerto por defecto 5410/tcp) de SiVMS/SiNVR Video Server contiene una vulnerabilidad de validación de entrada, que podría permitir a un atacante remoto no autenticado causar una condición de denegación de servicio mediante el envío de peticiones HTTP malformadas

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).
