CVE-2022-1390

Estado: ModificadaCrítica (9.8)—💥 Exploit

El plugin Admin Word Count Column de WordPress versiones hasta 2.2 no comprueba el parámetro de la ruta dado a readfile(), lo que podría permitir a atacantes no autenticados leer archivos arbitrarios en un servidor que ejecute una versión antigua de PHP susceptible a la técnica del byte nulo. Esto también podría conllevar un RCE al usar una técnica de deserialización de Phar

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.
