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.

There is an information leakage vulnerability on some Huawei products(AR120-S;AR1200;AR1200-S;AR150;AR150-S;AR160;AR200;AR200-S;AR2200;AR2200-S;AR3200;AR3600). An attacker with low permissions can view some high-privilege information by running specific commands.Successful exploit could cause an information disclosure condition.

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.

There is an out of bound read vulnerability in some Huawei products. A remote, unauthenticated attacker may send a corrupt or crafted message to the affected products. Due to a buffer read overflow error when parsing the message, successful exploit may cause some service to be abnormal.

Some Huawei products have a memory leak vulnerability when handling some messages. A remote attacker with operation privilege could exploit the vulnerability by sending specific messages continuously. Successful exploit may cause some service to be abnormal.
