CVE-2022-23748

Estado: AnalizadaAlta (7.8)⚠ Explotación activa

mDNSResponder.exe es vulnerable al ataque de carga lateral de DLL. El ejecutable especifica incorrectamente cómo cargar la DLL, desde qué carpeta y bajo qué condiciones. En estos escenarios, un atacante malintencionado podría estar utilizando el ejecutable válido y legítimo para cargar archivos maliciosos.

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).

CISA KEV — explotada activamente
