CVE-2018-7920

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.
