CVE-2018-0959 is a remote code execution vulnerability in Windows Hyper-V that allows an authenticated guest user to execute arbitrary code on the host server due to improper input validation. This critical flaw impacts various Windows client and server operating systems, including Windows 7, 8.1, 10, and multiple versions of Windows Server. With a CVSS score of 7.6 (HIGH), exploitation requires high privileges on the guest OS and high attack complexity, but successful execution grants complete compromise of the host (C:H/I:H/A:H). While not listed on the KEV catalog and lacking public exploit code in Metasploit or ExploitDB, its EPSS score indicates a higher-than-average probability of exploitation, and it garnered some community discussion and media coverage upon its disclosure in May 2018.
