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 buffer overflow vulnerability. 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.
The product copies an input buffer to an output buffer without verifying that the size of the input buffer is less than the size of the output buffer, leading to a buffer overflow.
