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.

The system dereferences a pointer that it expects to be valid, but is NULL. A local attacker could exploit this vulnerability by sending crafted parameters. A successful exploit could cause a denial of service and the process reboot.

An attacker who logs in to the board may send crafted messages from the internal network port or tamper with inter-process message packets to exploit this vulnerability. Due to insufficient validation of the message, successful exploit may cause the affected board to be abnormal.
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.
Huawei S5700 and S6700 have a DoS security vulnerability. Attackers with certain permissions perform specific operations on affected devices. Because the pointer in the program is not processed properly, the vulnerability can be exploited to cause the device to be abnormal.
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)
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 S12700 V200R005C00, V200R006C00, V200R007C00, V200R008C00, S5700 V200R006C00, V200R007C00, V200R008C00, S6700 V200R008C00, S7700 V200R001C00, V200R002C00, V200R003C00, V200R005C00, V200R006C00, V200R007C00, V200R008C00, S9700 V200R001C00, V200R002C00, V200R003C00, V200R005C00, V200R006C00, V200R007C00, V200R008C00 have a denial of service (DoS) vulnerability. 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 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.
