NVD Analysts use publicly available information to associate vector strings and CVSS scores. A miscalculation creates an integer overflow that causes less memory to be allocated than expected, which in turns leads to a. [24], The NSA recommended additional measures, such as disabling Remote Desktop Services and its associated port (TCP 3389) if it is not being used, and requiring Network Level Authentication (NLA) for RDP. Both have a _SECONDARY command that is used when there is too much data to include in a single packet. [8][9][7], On the same day as the NSA advisory, researchers of the CERT Coordination Center disclosed a separate RDP-related security issue in the Windows 10 May 2019 Update and Windows Server 2019, citing a new behaviour where RDP Network Level Authentication (NLA) login credentials are cached on the client system, and the user can re-gain access to their RDP connection automatically if their network connection is interrupted. Supports both x32 and x64. Ensuring you have a capable EDR security solution should go without saying, but if your organization is still behind the curve on that one, remember that passive EDR solutions are already behind-the-times.
