Huawei AR200

There is a few bytes out-of-bounds read vulnerability in some Huawei products. The software reads data past the end of the intended buffer when parsing certain message, an authenticated attacker could exploit this vulnerability by sending crafted messages to the device. Successful exploit may cause service abnormal in specific scenario.Affected product versions include:AR120-S versions V200R007C00SPC900,V200R007C00SPCa00

Some Huawei products have an insufficient verification of data authenticity vulnerability. A remote, unauthenticated attacker has to intercept specific packets between two devices, modify the packets, and send the modified packets to the peer device. Due to insufficient verification of some fields in the packets, an attacker may exploit the vulnerability to cause the target device to be abnormal.
