An attacker who successfully exploited the vulnerability could run arbitrary code with elevated privileges.\nTo exploit this vulnerability an attacker would need to physically access the booted machine to reach the logon screen. An attacker could then exploit the vulnerability and take control of an affected system.\nThe update addresses the vulnerability by correcting how the Windows handles errors tied to Remote Access Common Dialog.\n\n## Affected\n\n- `windows_10`\n- `windows_10 = 1607`\n- `windows_10 = 1709`\n- `windows_10 = 1803`\n- `windows_10 = 1809`\n- `windows_10 = 1903`\n- `windows_10 = 1909`\n- `windows_7`\n- `windows_8.1`\n- `windows_rt_8.1`\n- `windows_server_2008`\n- `windows_server_2008 = r2`\n- `windows_server_2012`\n- `windows_server_2012 = r2`\n- `windows_server_2016`\n- `windows_server_2019`\n- `windows_server_2019 = 1903`\n- `windows_server_2019 = 1909`\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"sunlit","depthScore":38,"depthScoreParts":{"impact":37.4,"likelihood":0.2,"exploitation":0,"ransomware":0},"changes":[]}
