Descriptions

Huawei AR1200 V200R006C10SPC300, AR160 V200R006C10SPC300, AR200 V200R006C10SPC300, AR2200 V200R006C10SPC300, AR3200 V200R006C10SPC300 devices have an improper resource management vulnerability. Due to the improper implementation of ACL mechanism, a remote attacker may send TCP messages to the management interface of the affected device to exploit this vulnerability. Successful exploit could exhaust the socket resource of management interface, leading to a DoS condition.

Los dispositivos Huawei AR1200 V200R006C10SPC300, AR160 V200R006C10SPC300, AR200 V200R006C10SPC300, AR2200 V200R006C10SPC300 y AR3200 V200R006C10SPC300 tienen una vulnerabilidad de gestión incorrecta de recursos. Debido a la implementación incorrecta del mecanismo de lista de control de acceso (ACL), un atacante remoto podría enviar mensajes TCP a la interfaz de gestión del dispositivo afectado para explotar esta vulnerabilidad. Un exploit con éxito podría agotar el recurso socket de la interfaz de gestión, lo que conduce a una condición de denegación de servicio (DoS).
