There is an information leak vulnerability in Huawei products. A module does not deal with specific input sufficiently. High privilege attackers can exploit this vulnerability by performing some operations. This can lead to information leak. Affected product versions include: IPS Module versions V500R005C00, V500R005C10, V500R005C20; NGFW Module versions V500R005C00,V500R005C10, V500R005C20; SeMG9811 versions V500R005C00; USG9500 versions V500R001C00, V500R001C20, V500R001C30, V500R001C50, V500R001C60, V500R001C80, V500R005C00, V500R005C10, V500R005C20.

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.

Some Huawei products have a command injection vulnerability. Due to insufficient input validation, an attacker with high privilege may inject some malicious codes in some files of the affected products. Successful exploit may cause command injection.Affected product versions include:NIP6300 versions V500R001C30,V500R001C60;NIP6600 versions V500R001C30,V500R001C60;Secospace USG6300 versions V500R001C30,V500R001C60;Secospace USG6500 versions V500R001C30,V500R001C60;Secospace USG6600 versions V500R001C30,V500R001C60;USG9500 versions V500R001C30,V500R001C60.

There is an out-of-bounds write vulnerability in some products. An unauthenticated attacker crafts malformed packets with specific parameter and sends the packets to the affected products. Due to insufficient validation of packets, which may be exploited to cause the process reboot. Affected product versions include: IPS Module versions V500R005C00, V500R005C10; NGFW Module versions V500R005C00, V500R005C10; Secospace USG6300 versions V500R001C30, V500R001C60, V500R005C00, V500R005C10; Secospace USG6500 versions V500R001C30, V500R001C60, V500R005C00, V500R005C10; Secospace USG6600 versions V500R001C30, V500R001C60, V500R005C00, V500R005C10; USG9500 versions V500R001C30, V500R001C60, V500R005C00, V500R005C10

USG9500 with versions of V500R001C30;V500R001C60 have a missing integrity checking vulnerability. The software of the affected products does not check the integrity which may allow an attacker with high privilege to make malicious modifications without detection.
