CVE-2021-44664
Se presenta una vulnerabilidad de Ejecución de Código Remoto Autenticado (RCE) en Xerte versiones hasta 3.9, en el archivo website_code/php/import/fileupload.php al subir un archivo PHP maliciosamente diseñado mediante la interfaz del proyecto disfrazado como un archivo de lenguaje para omitir los filtros de subida. Los atacantes pueden manipular el destino de los archivos al abusar del salto de ruta en la variable "mediapath"
CVSS
- Puntuación base
- 8.8
- Versión
- 3.1
- Vector
- CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Probabilidad de explotación (EPSS)
- Probabilidad de explotación en los próximos 30 días
- 13 %
- Percentil entre todas las CVEs puntuadas
- 96
- Fecha de la puntuación
- 26/10/2026
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.
