Vulnerability Assessment Details

TCP Chorusing

Vulnerability Assessment Summary
Counts the number of ACKs to a SYN

Detailed Explanation for this Vulnerability Assessment

Microsoft Windows 95 and 98 clients have the ability
to bind multiple TCP/IP stacks on the same MAC address,
simply by having the protocol added more than once
in the Network Control panel.

The remote host has several TCP/IP stacks with the
same IP bound on the same MAC address. As a result,
it will reply several times to the same packets,
such as by sending multiple ACK to a single SYN,
creating noise on your network. If several hosts
behave the same way, then your network will be brought
down.

Solution : Remove all the IP stacks except one in the remote
host.
Network Security Threat Level: Medium

Networks Security ID: 225
