Unreal IRCd IP cloaking weakness

Vulnerability Assessment Summary
checks the version of the remote ircd

Detailed Explanation for this Vulnerability Assessment

The remote host is running Unreal IRCD, a popular IRC server.

The remote version of this server offers an 'IP cloaking' capability which
offers to hide the IP address of the users connected to the server, in
order to preserve their anonymity.

There is a design error in the algorithm used by the server which may
permit a possible hacker to guess the real IP address of another user of the server,
by reducing the number of tries to 2,000.

Solution : Upgrade to UnrealIRCD 3.2.1
Network Security Threat Level: Medium

Networks Security ID: 10663
