After launching the application successfully, command line parameters can be used in getting the URL that launched it (Farrel, 2004). This is possible for, the protocols run within Windows Explorer and Windows Internet Explorer by using the Run command. These applications for URL protocols should have a mechanism of acting on malicious data. This is so because application handlers can get data from un-trusted sources.

The simplicity makes the launching the protocols to be easier in windows web browsers. The browsers include; Safari, Chrome, Opera, IE, and Firefox support the application protocols. This is done by the use of Windows ShellExecuteEx. However, the browsers behave differently in launching the protocols. This simplicity makes the application protocols acutely vulnerable.
