The issue is when you have a malformed id in your query string Interchange actually prints out something along the lines of "Invalid session ID: 3Cscript%3Ealert('TK00000008')%3C/script%3E. Logged". Well the security scanner sees the fact that it printed the alert on the page and determines that you have an cross-site scripting vulnerability. I've had to challenge their finding and have them run it by hand to show them that it's not actually running the alert. I think for another client we modified that part of Interchange so it didn't print out the invalid id.
