arbitrary HOST HEADER Vulnerability - Exchange 2019

Copper Contributor

Hello All,

 

I would like to know if one member here has implemented the mitigation for 

arbitrary HTTP Host headers in Exchange Server 2019 On Premises Edition ?

 

The security team has found this vulnerability on Exchange servers and has asked to mitigate it, but I don't see any documentation on how this can be mitigated for Exchange 2019.

 

Any ideas or implementation links would be appreciated.

 

Kind Regards
