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)

The system incorrectly performs an authorization check when a normal user attempts to access certain information which is supposed to be accessed only by authenticated user. Successful exploit could cause information disclosure.
