ZTE ZXHN H168N product with versions V2.2.0_PK1.2T5, V2.2.0_PK1.2T2, V2.2.0_PK11T7 and V2.2.0_PK11T have an improper access control vulnerability, which may allow an unauthorized user to gain unauthorized access.

The TCP implementation in (1) Linux, (2) platforms based on BSD Unix, (3) Microsoft Windows, (4) Cisco products, and probably other operating systems allows remote attackers to cause a denial of service (connection queue exhaustion) via multiple vectors that manipulate information in the TCP state table, as demonstrated by sockstress.
