      "value": "FileCodeBox before 2.4 contains a rate-limit bypass vulnerability in the IPRateLimit class that allows unauthenticated attackers to circumvent request throttling by supplying attacker-controlled X-Real-IP and X-Forwarded-For headers without verification of trusted reverse proxy origin. Attackers can supply unique spoofed IP values on each request to enumerate all possible share codes and retrieve other users' files without authentication."

      "value": "FileCodeBox antes de 2.4 contiene una vulnerabilidad de omisión de límite de tasa en la clase IPRateLimit que permite a atacantes no autenticados eludir la limitación de solicitudes al suministrar encabezados X-Real-IP y X-Forwarded-For controlados por el atacante sin verificación del origen de un proxy inverso de confianza. Los atacantes pueden suministrar valores de IP falsificados únicos en cada solicitud para enumerar todos los códigos de compartición posibles y recuperar archivos de otros usuarios sin autenticación."
