📋 Description

According to the CVSS metric, the attack complexity is high (AC:H). What does that mean for this vulnerability? Successful exploitation of this vulnerability requires an attacker to possess advanced reverse engineering skills to identify and gain unauthorized access to specific remote procedure call (RPC) endpoints.

Are there additional actions I need to take after I have installed the update? Yes. If your RD session hosts and RD licensing servers are joined to a work group, you need to ensure that your RD session hosts have the necessary credentials to access your RD licensing servers. For more information see: License Remote Desktop session hosts. No additional action is needed for RD session hosts and RD licensing servers joined to a domain.
