Huawei NGFW Module, NIP6300, NIP6600, Secospace USG6500, Secospace USG6600, and USG9500 versions V500R001C30, V500R001C60, and V500R005C00 have an information leakage vulnerability. An attacker can exploit this vulnerability by sending specific request packets to affected devices. Successful exploit may lead to information leakage.
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.
Some Huawei products IPS Module V500R001C50; NGFW Module V500R001C50; V500R002C10; NIP6300 V500R001C50; NIP6600 V500R001C50; NIP6800 V500R001C50; Secospace USG6600 V500R001C50; USG9500 V500R001C50 have a memory leak vulnerability. The software does not release allocated memory properly when processing Protal questionnaire. A remote attacker could send a lot questionnaires to the device, successful exploit could cause the device to reboot since running out of memory.
