Huawei ar200-s Firmware v200r008c50

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.
