There is a denial of service vulnerability in some huawei products. In specific scenarios, due to the improper handling of the packets, an attacker may craft many specific packets. Successful exploit may cause some services to be abnormal. Affected products include some versions of NGFW Module, NIP6300, NIP6600, NIP6800, Secospace USG6300, Secospace USG6500, Secospace USG6600 and SG9500.

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

Huawei products Secospace USG6300;USG6300E with versions of V500R001C30,V500R001C50,V500R001C60,V500R001C80,V500R005C00,V500R005C10;V600R006C00 have a vulnerability of insufficient input verification. An attacker with limited privilege can exploit this vulnerability to access a specific directory. Successful exploitation of this vulnerability may lead to information leakage.

Huawei products IPS Module; NGFW Module; NIP6300; NIP6600; NIP6800; Secospace USG6300; Secospace USG6500; Secospace USG6600; USG9500 with versions of V500R001C00; V500R001C20; V500R001C30; V500R001C50; V500R001C60; V500R001C80; V500R005C00; V500R005C10; V500R005C20; V500R002C00; V500R002C10; V500R002C20; V500R002C30 have an improper authentication vulnerability. Attackers need to perform some operations to exploit the vulnerability. Successful exploit may obtain certain permissions on the device.

Some Huawei products have a buffer error vulnerability. An unauthenticated, remote attacker could send specific MPLS Echo Request messages to the target products. Due to insufficient input validation of some parameters in the messages, successful exploit may cause the device to reset.

Certain Huawei products (AP2000;IPS Module;NGFW Module;NIP6300;NIP6600;NIP6800;S5700;SVN5600;SVN5800;SVN5800-C;SeMG9811;Secospace) have a resource management vulnerability. An attacker who logs in to the board may send crafted messages from the internal network.

Certain Huawei products (AP2000;IPS Module;NGFW Module;NIP6300;NIP6600;NIP6800;S5700;SVN5600;SVN5800;SVN5800-C;SeMG9811;Secospace AntiDDoS8000;Secospace USG6300;Secospace USG6500;Secospace USG6600;USG6000V;eSpace U1981) have a DoS vulnerability. An attacker may send crafted messages from a FTP client to exploit this vulnerability. Due to insufficient validation of the message, successful exploit may cause the system out-of-bounds read and result in a denial of service condition of the affected service.
