How do I turn off ssl 3.0 support in the web server? (CVE-2014-3566 poodle)

neilgbrookins over 9 years ago

I'm using ipMonitor which has a build-in web server. I need to turn off SSL 3.0 support in the server to prevent an attack via poodle, CVE-2014-3566.

Is there a setting that allows this to be accomplished?

Would you like to turn off HTTPS access? Also what kind of certificate are you using?

No, I don't want to turn off https. I want to force the use of tls and not allow ssl 3 at all. Please google for poodle for more details.

Hi, you can force TLS communication channel instead of using SSLv3 by adding registry entries mentioned bellow.
Just open your command line with Run as administrator and paste these commands:
REG ADD "HKLM\System\CurrentControlSet\Control\SecurityProviders\SChannel\Protocols\SSL 2.0\Server" /v Enabled /t REG_DWORD /d 0 /f
REG ADD "HKLM\System\CurrentControlSet\Control\SecurityProviders\SChannel\Protocols\SSL 2.0\Client" /v Enabled /t REG_DWORD /d 0 /f
REG ADD "HKLM\System\CurrentControlSet\Control\SecurityProviders\SChannel\Protocols\SSL 3.0\Server" /v Enabled /t REG_DWORD /d 0 /f
REG ADD "HKLM\System\CurrentControlSet\Control\SecurityProviders\SChannel\Protocols\SSL 3.0\Client" /v Enabled /t REG_DWORD /d 0 /f
REG ADD "HKLM\System\CurrentControlSet\Control\SecurityProviders\SChannel\Protocols\SSL 2.0\Server" /v DisabledByDefault /t REG_DWORD /d 1 /f
REG ADD "HKLM\System\CurrentControlSet\Control\SecurityProviders\SChannel\Protocols\SSL 2.0\Client" /v DisabledByDefault /t REG_DWORD /d 1 /f
REG ADD "HKLM\System\CurrentControlSet\Control\SecurityProviders\SChannel\Protocols\SSL 3.0\Server" /v DisabledByDefault /t REG_DWORD /d 1 /f
REG ADD "HKLM\System\CurrentControlSet\Control\SecurityProviders\SChannel\Protocols\SSL 3.0\Client" /v DisabledByDefault /t REG_DWORD /d 1 /f
REG ADD "HKLM\System\CurrentControlSet\Control\SecurityProviders\SChannel\Protocols\TLS 1.0\Server" /v Enabled /t REG_DWORD /d 1 /f
REG ADD "HKLM\System\CurrentControlSet\Control\SecurityProviders\SChannel\Protocols\TLS 1.0\Client" /v Enabled /t REG_DWORD /d 1 /f
REG ADD "HKLM\System\CurrentControlSet\Control\SecurityProviders\SChannel\Protocols\TLS 1.1\Server" /v Enabled /t REG_DWORD /d 1 /f
REG ADD "HKLM\System\CurrentControlSet\Control\SecurityProviders\SChannel\Protocols\TLS 1.1\Client" /v Enabled /t REG_DWORD /d 1 /f
REG ADD "HKLM\System\CurrentControlSet\Control\SecurityProviders\SChannel\Protocols\TLS 1.2\Server" /v Enabled /t REG_DWORD /d 1 /f
REG ADD "HKLM\System\CurrentControlSet\Control\SecurityProviders\SChannel\Protocols\TLS 1.2\Client" /v Enabled /t REG_DWORD /d 1 /f
Then restart your OS and now only TLS channels could be used.
