and missed some more REALLY nice vulnerabilities (just like the one
Microsoft fixed with <https://support.microsoft.com/kb/2781197>
alias <http://technet.microsoft.com/security/bulletin/ms13-034>,
which of course is present too).


A.6: TWO vulnerabilities in the preinstalled services from Fujitsu:

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\PFNService]
"ImagePath"=expand:"C:\\Program Files\\Fujitsu\\Plugfree NETWORK\\PFNService.exe"

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\PowerSavingUtilityService]
"ImagePath"=expand:"C:\\Program Files\\Fujitsu\\PSUtility\\PSUService.exe"


A.7: SIX vulnerabilities in the preinstalled services from Intel:

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\AMPPALR3]
"ImagePath"=expand:"C:\\Program Files\\Intel\\BluetoothHS\\BTHSAmpPalService.exe"

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\EvtEng]
"ImagePath"=expand:"C:\\Program Files\\Intel\\WiFi\\bin\\EvtEng.exe"

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\jhi_service]
"ImagePath"=expand:"C:\\Program Files (x86)\\Intel\\Intel(R) Management Engine Components\\DAL\\jhi_service.exe"

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LMS]
"ImagePath"=expand:"C:\\Program Files (x86)\\Intel\\Intel(R) Management Engine Components\\LMS\\LMS.exe"

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MyWiFiDHCPDNS]
"ImagePath"=expand:"C:\\Program Files\\Intel\WiFi\\bin\\PanDhcpDns.exe"

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\RegSrvc]
"ImagePath"=expand:"C:\\Program Files\\Common Files\\Intel\\WirelessCommon\RegSrvc.exe"


JFTR: two other services of Intel don't show this vulnerability!

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\BTHSSecurityMgr]
"ImagePath"=expand:"""C:\\Program Files\\Intel\\BluetoothHS\\BTHSSecurityMgr.exe"""

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\UNS]
"ImagePath"=expand:"""C:\\Program Files (x86)\\Intel\\Intel(R) Management Engine Components\\UNS\\UNS.exe"""
