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 an out-of-bounds read vulnerability in several products. The software reads data past the end of the intended buffer when parsing certain crafted DHCP messages. Successful exploit could cause certain service abnormal. Affected product versions include:NIP6800 versions V500R001C30,V500R001C60SPC500,V500R005C00;S12700 versions V200R008C00;S2700 versions V200R008C00;S5700 versions V200R008C00;S6700 versions V200R008C00;S7700 versions V200R008C00;S9700 versions V200R008C00;Secospace USG6600 versions V500R001C30SPC200,V500R001C30SPC600,V500R001C60SPC500,V500R005C00;USG9500 versions V500R001C30SPC300,V500R001C30SPC600,V500R001C60SPC500,V500R005C00.

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)

Due to the lack of input validation, a remote attacker may craft a malformed Resource Reservation Protocol (RSVP) packet and send it to the device, causing a few buffer overflows and occasional device restart.

Huawei S12700 V200R007C00, V200R008C00, S5700 V200R007C00, S7700 V200R002C00, V200R005C00, V200R006C00, V200R007C00, V200R008C00, S9700 V200R007C00 have an input validation vulnerability. Due to the lack of input validation, an attacker may craft a malformed packet and send it to the device using VRP, causing the device to display additional memory data and possibly leading to sensitive information leakage.

Huawei AR120-S V200R005C32; AR1200 V200R005C32; AR1200-S V200R005C32; AR150 V200R005C32; AR150-S V200R005C32; AR160 V200R005C32; AR200 V200R005C32; AR200-S V200R005C32; AR2200-S V200R005C32; AR3200 V200R005C32; V200R007C00; AR510 V200R005C32; NetEngine16EX V200R005C32; SRG1300 V200R005C32; SRG2300 V200R005C32; SRG3300 V200R005C32 have an out-of-bounds write vulnerability. When a user executes a query command after the device received an abnormal OSPF message, the software writes data past the end of the intended buffer due to the insufficient verification of the input data. An unauthenticated, remote attacker could exploit this vulnerability by sending abnormal OSPF messages to the device. A successful exploit could cause the system to crash.
