All versions up to V3.03.10.B23P2 of ZTE ZXR10 8905E product are impacted by TCP Initial Sequence Number (ISN) reuse vulnerability, which can generate easily predictable ISN, and allows remote attackers to spoof connections.

Weakness

A capture-replay flaw exists when the design of the product makes it possible for a malicious user to sniff network traffic and bypass authentication by replaying it to the server in question to the same effect as the original message (or with minor changes).
