CVE-2026-5509
Full vulnerability record from the local CVENow database.
Description
An authenticated command injection vulnerability exists in the Archer BE450 v1 and BE7200 v1 router that allows an administrator to execute arbitrary system commands through the web management interface. After successfully authenticating to the admin interface, an attacker can leverage the browser’s developer console by supplying a crafted input that is passed to backend system commands without adequate sanitization. Successful exploitation enables execution of arbitrary commands with elevated privileges on the device, which may allow the attacker to start unauthorized services, modify system configuration, or otherwise fully compromise the router’s operating environment.

Después de autenticarse exitosamente en la interfaz de administración, un atacante puede aprovechar la consola de desarrollador del navegador al proporcionar una entrada manipulada que se pasa a los comandos del sistema de backend sin una sanitización adecuada.\n\nLa explotación exitosa permite la ejecución de comandos arbitrarios con privilegios elevados en el dispositivo, lo que puede permitir al atacante iniciar servicios no autorizados, modificar la configuración del sistema o de otro modo comprometer completamente el entorno operativo del router."
