Spring Security's @PreAuthorize is used for authorizing access to methods. It doesn't know really much about Spring MVC, in particular about its @RequestMapping annotation.

Names like #cmd will refer to method parameters, and your cmd parameter is null. Change it to:

@PathVariable("cmd") String cmd

This way, cmd path variable will be bound to cmd method parameter, which will then be bound by #cmd in @PreAuthorize.
