Summary
An OS command injection vulnerability exists in the OptiLink ONT1GEW GPON router firmware version V2.1.11_X101 Build 1127.190306 and earlier. The router’s web management interface fails to properly sanitize user input in the target_addr parameter of the formTracert and formPing administrative endpoints. An authenticated attacker can inject arbitrary operating system commands, which are executed with root privileges, leading to remote code execution. Successful exploitation enables full compromise of the device.

La interfaz de administraci\u00f3n web del router no depura correctamente la entrada del usuario en el par\u00e1metro target_addr de los endpoints administrativos formTracert y formPing. Un atacante autenticado puede inyectar comandos arbitrarios del sistema operativo, que se ejecutan con privilegios de root, lo que provoca la ejecuci\u00f3n remota de c\u00f3digo. Una explotaci\u00f3n exitosa permite la vulneraci\u00f3n total del dispositivo."
