CVE-2020-1814
Estado: ModificadaMedia (5.3)—
Huawei NIP6800 versions V500R001C30, V500R001C60SPC500, and V500R005C00; Secospace USG6600 and USG9500 versions V500R001C30SPC200, V500R001C30SPC600, V500R001C60SPC500, and V500R005C00 have a Dangling pointer dereference vulnerability. An authenticated attacker may do some special operations in the affected products in some special scenarios to exploit the vulnerability. Due to improper race conditions of different operations, successful exploit will lead to Dangling pointer dereference, causing some service abnormal.
