Microsoft Windows Remote Desktop Protocol CVE-2017-8673 Denial of Service Vulnerability

Description

Microsoft Windows Remote Desktop Protocol is prone to a denial-of-service vulnerability. An attacker can exploit this issue to cause the target service to stop responding, denying service to legitimate users.

Technologies Affected

• Microsoft Windows 10 version 1703 for 32-bit Systems
• Microsoft Windows 10 version 1703 for x64-based Systems

Recommendations

Block external access at the network boundary, unless external parties require service.
Filter access to the affected computer at the network boundary if global access isn’t required. Restricting access to only trusted computers and networks might greatly reduce the likelihood of exploits.

Run all software as a nonprivileged user with minimal access rights.
To mitigate the potential impact of a successful exploit, run the affected application as a user with minimal access rights.

Deploy network intrusion detection systems to monitor network traffic for malicious activity.
Deploy NIDS to monitor network traffic for anomalous or suspicious activity. Monitor logs generated by NIDS and by the server itself for evidence of attacks against the server.

Updates are available. Please see the references or vendor advisory for more information.
