Some Huawei S series switches have a DoS vulnerability. An unauthenticated remote attacker can send crafted packets to the affected device to exploit this vulnerability. Due to insufficient verification of the packets, successful exploitation may cause the device reboot and denial of service (DoS) condition. (Vulnerability ID: HWPSIRT-2019-03109)
