The following cookies control the user's login session and can be trivially modified to login as admin or any other known username. The 'loggedinuserusergroup' can be set to 'administrator' to gain full privileges.
loggedinenduser, loggedinendusername, loggedinuserusergroup (administrator), loggedinuser, loggedinusername
An attacker can login as any user he/she wishes and make arbitrary changes to the application data.
Layton advise upgrading to their newer 'ServiceDesk' product. However, if you have an active support contract, Layton may be able to provide fixes for you.
