  Telefonica O2 Connection Manager 8.7 Service Trusted Path Privilege Escalation
  
  
  Vendor: Telefonica S.A.
  Product web page: http://www.telefonica.com | http://www.o2.co.uk
  Affected version: 8.7.6.792
  
  Summary: O2 Connection Manager will help you to manage your internet
  connections by getting you connected to the fastest available network.
  Automatically connect you to the fastest available network including
  your home broadband if you have a wireless router.
  
  Desc: The O2 Connection Manager's service suffers from an unquoted
  search path issue impacting the Import WiFi 'TGCM_ImportWiFiSvc'
  service for Windows. This could potentially allow an authorized but
  non-privileged local user to execute arbitrary code with elevated
  privileges on the system. A successful attempt would require the
  local user to be able to insert their code in the system root path
  undetected by the OS or other security applications where it could
  potentially be executed during application startup or reboot. If
  successful, the local user’s code would execute with the elevated
  privileges of the application. 
  
  Tested on: Microsoft Windows 7 Professional SP1 (EN)
   Microsoft Windows 7 Ultimate SP1 (EN)
