Huawei IPS Module V500R001C00, NGFW Module V500R001C00, NIP6300 V500R001C00, NIP6600 V500R001C00, Secospace USG6300 V500R001C00, Secospace USG6500 V500R001C00, Secospace USG6600 V500R001C00, USG9500 V500R001C00 have an insufficient input validation 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.

The SIP module of some Huawei products have a denial of service (DoS) vulnerability. A remote attacker could exploit these three vulnerabilities by sending the specially crafted messages to the affected device. Due to the insufficient verification of the packets, successful exploit could allow the attacker to cause buffer overflow and dead loop, leading to DoS condition. Affected products can be found in https://www.huawei.com/en/psirt/security-advisories/huawei-sa-20200115-01-sip-en.
