Hafnium - Patch for Server 2013 only with installed CU 23 ?

Dear community

 

I try to figure out if the patch for Exchange 2013 only can be installed if you have CU23 already installed ( Screenshot).

Does someone know if this is really true? We have planned to install an Exchange Server 2016 and move all mail boxes to that server and uninstall Ex2013 but that was planned for next week so we are now in a bad situation. Does someone know if this update only works with CU 23 installed and if that is true, how can we minimize the threat for our EX 2013 ?
