The vulnerability could allow elevation of privilege if an attacker can successfully exploit it.\nAn attacker who successfully exploited the vulnerability could gain greater access to sensitive information and system functionality. To exploit the vulnerability, an attacker could run a specially crafted application.\nThe security update addresses the vulnerability by correcting the way that WER handles and executes files.\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_server_2016`\n- `windows_server_2019`\n- `windows_server_2019 = 1803`\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":"twilight","depthScore":43,"depthScoreParts":{"impact":42.9,"likelihood":0.2,"exploitation":0,"ransomware":0},"changes":[]}
