   * CWE: 78 OS Command Injection
   * BadSource: console Read input from the console
   * GoodSource: Fixed string
   * Sink: execlp
   *    BadSink : execute command with wexeclp
   * Flow Variant: 22 Control flow: Flow controlled by value of a global variable. Sink functions are in a separate file from sources.
