CVE-2024-49117

22
FAUCET Score

CVE-2024-49117 is a critical Remote Code Execution (RCE) vulnerability affecting Microsoft Windows Hyper-V, impacting Windows 11 (22H2, 23H2, 24H2) and Windows Server (2022, 2022 23H2, 2025). With a CVSS score of 8.8 (High), it allows a low-privileged attacker to achieve RCE with high impact on confidentiality, integrity, and availability, though it requires local access and no user interaction. While not currently listed in CISA's KEV catalog or having public exploit code (Metasploit, Nuclei, ExploitDB), its high FAUCET Risk Score of 70/100, significant community discussion, and media coverage indicate considerable attention and potential for future exploitation.
