A vulnerability in PKI Security Solution of Dream Security could allow arbitrary command execution. This vulnerability is due to insufficient validation of the authorization certificate. An attacker could exploit this vulnerability by sending a crafted HTTP request an affected program. A successful exploit could allow the attacker to remotely execute arbitrary code on a target system.

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).
