Estado: ModificadaCrítica (9.8)—💥 Exploit

Una ejecución de código remota en Monitorr versión v1.7.6m, en el archivo upload.php permite a una persona no autorizada ejecutar código arbitrario en el lado del servidor por medio de una carga de archivo no segura

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).

💥 Exploits públicos

Hay código de explotación o plantillas de detección públicos. No es lo mismo que explotación activa confirmada (KEV), pero aumenta el riesgo: parchee con prioridad.
