Microsoft Windows Hyper-V CVE-2019-0721 Remote Code Execution Vulnerability

Description

Microsoft Windows is prone to a remote code-execution vulnerability. An attacker can exploit this issue to execute arbitrary code in the context of an affected system.

Technologies Affected

• Microsoft Hyper-V
• Microsoft Windows 10 Version 1803 for x64-based Systems
• Microsoft Windows 10 Version 1809 for x64-based Systems
• Microsoft Windows 10 Version 1903 for x64-based Systems
• Microsoft Windows 10 version 1709 for x64-based Systems
• Microsoft Windows Server 1803
• Microsoft Windows Server 1903
• Microsoft Windows Server 2019

Recommendations

Run all software as a nonprivileged user with minimal access rights.
To reduce the impact of latent vulnerabilities, always run nonadministrative software as an unprivileged user with minimal access rights.

Deploy network intrusion detection systems to monitor network traffic for malicious activity.
Deploy NIDS to monitor network traffic for signs of anomalous or suspicious activity. This includes but is not limited to requests that include NOP sleds and unexplained incoming and outgoing traffic. This may indicate exploit attempts or activity that results from successful exploits

Implement multiple redundant layers of security.
Memory-protection schemes (such as nonexecutable stack and heap configurations and randomly mapped memory segments) will complicate exploits of memory-corruption vulnerabilities.

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