Descriptions

The IntelliSpace portal application utilizes .NET
Remoting for its functionality. The vulnerability arises from the exploitation
of port 755 through the "Object Marshalling" technique, which allows
an attacker to read internal files without any authentication. This is possible
by crafting specific .NET Remoting URLs derived from information enumerated in
the client-side configuration files. This issue affects IntelliSpace Portal: 12 and prior.
