  • MitigationBeckhoff Embedded PC Images

    Beckhoff also recommends the following mitigation solutions: Update images to build October 22, 2014, or newer, which solve these problems by disabling the services by default. Disable the Windows CE Remote Configuration Tool by deleting the subtree “/remoteadmin.” The configuration of the web server paths can be found in the Windows registry at the path “HKEY_LOCAL_MACHINE\COMM\HTTPD\VROOTS\.” Disable startup of CE Remote Display service (cerdisp.exe) with deleting the registry key containing the “CeRDisp.exe” [-HKEY_LOCAL_MACHINE\init\Launch90]. Disable telnet by setting the registry key [HKEY_LOCAL_MACHINE\Services\TELNETD\Flags] to dword: 4, Restrict ADS communication to trusted networks only.
