CVE-2020-1816
Estado: ModificadaAlta (7.5)—
Huawei NIP6800 versions V500R001C30, V500R001C60SPC500, and V500R005C00; Secospace USG6600 and USG9500 versions V500R001C30SPC200, V500R001C30SPC600, V500R001C60SPC500, and V500R005C00 have a Denial of Service (DoS) vulnerability. Due to improper processing of specific IPSEC packets, remote attackers can send constructed IPSEC packets to affected devices to exploit this vulnerability. Successful exploit could cause the IPSec function of the affected device abnormal.
