There is a weak algorithm vulnerability in some Huawei products. The affected products use weak algorithms by default. Attackers may exploit the vulnerability to cause information leaks.

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)
