There has a license management vulnerability in some Huawei products. An attacker with high privilege needs to perform specific operations to exploit the vulnerability on the affected device. Due to improper license management of the device, as a result, the license file can be applied and affect integrity of the device. Affected product versions include:S12700 V200R007C01,V200R007C01B102,V200R008C00,V200R010C00SPC300,V200R011C00,V200R011C00SPC100,V200R011C10;S1700 V200R010C00SPC300,V200R011C00,V200R011C00SPC100,V200R011C10;S2700 V200R008C00,V200R010C00SPC300,V200R011C00,V200R011C00SPC100,V200R011C10;S5700 V200R008C00,V200R010C00SPC300,V200R011C00,V200R011C00SPC100,V200R011C10,V200R011C10SPC100;S6700 V200R008C00,V200R010C00SPC300,V200R011C00,V200R011C00SPC100,V200R011C10,V200R011C10SPC100;S7700 V200R008C00,V200R010C00SPC300,V200R011C00,V200R011C00SPC100,V200R011C10;S9700 V200R007C01,V200R007C01B102,V200R008C00,V200R010C00SPC300,V200R011C00,V200R011C00SPC100,V200R011C10.

There is a use-after-free vulnerability in a Huawei product. A module cannot deal with specific operations in special scenarios. Attackers can exploit this vulnerability by performing malicious operations. This can cause memory use-after-free, compromising normal service. Affected product include some versions of NIP6300, NIP6600, NIP6800, S1700, S2700, S5700, S6700 , S7700, S9700, Secospace USG6300, Secospace USG6500, Secospace USG6600 and USG9500.

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)
