Versions 2.0.14 and below use Gin's default configuration which trusts all IP addresses as proxies (TrustedProxies = 0.0.0.0/0), allowing any client to spoof the X-Forwarded-For header. Since all IP-based access controls (AllowIPs, API whitelists, localhost-only checks) rely on ClientIP(), attackers can bypass these protections by simply sending X-Forwarded-For:  127.0.0.1 or any whitelisted IP. This renders all IP-based security controls ineffective. This issue is fixed in version 2.0.14."},{"lang":"es","value":"1Panel es un panel de control de código abierto, basado en web, para la gestión de servidores Linux. Las versiones 2.0.14 e inferiores utilizan la configuración predeterminada de Gin que confía en todas las direcciones IP como proxies (TrustedProxies = 0.0.0.0/0), permitiendo a cualquier cliente falsificar el encabezado X-Forwarded-For. Dado que todos los controles de acceso basados en IP (AllowIPs, listas blancas de API, comprobaciones de solo localhost) dependen de ClientIP(), los atacantes pueden eludir estas protecciones simplemente enviando X-Forwarded-For: 127.0.0.1 o cualquier IP en la lista blanca. Esto hace que todos los controles de seguridad basados en IP sean ineficaces.
