Details :
During Startup, the SR_Watchdog.exe spawns the GUI process (SR_GUI.exe) through the use of the CreateProcess() function. By doing so it omits to set the 'lpApplicationName' variable and further omits to quote the path in the variable "lpCommandLine". Ref [1]

This results in c:\program.bat|exe|com being called prior to Sr_GUI.exe and allows automatic startup of a potentially rogue application. In particular one could imagine a scenario where it is possible to escalate
rights using this (as they are inherited from SR_Watchdog.exe).

I decided that this is not worth to report to the vendor, I consider this low impact in terms of Security. (Although it might show bad coding practice).
