Huawei s6700 Firmware v200r005c01

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.

An unauthenticated attacker may send crafted malformed IPv6 packets to the affected products. Due to insufficient verification of the packets, successful exploit will cause device to reset.

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.

There is a weak algorithm vulnerability in some Huawei products. The affected products use the RSA algorithm in the SSL key exchange algorithm which have been considered as a weak algorithm. Attackers may exploit this vulnerability to leak some information.

In some specific conditions, if attackers send specific malformed MPLS Service PING messages to the affected products, products do not release the memory when handling the packets. So successful exploit will result in memory leak of the affected products.
