'Description' => %q{
This module exploits a stack buffer overflow in the create folder function
in Sysax Multi Server 5.64. This issue was fixed in 5.66.
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 SP3, and Server 2003 SP1-SP2.
