An attacker who successfully exploits this vulnerability can run arbitrary code with the privileges of the calling application. The attacker can then install programs, view, change, or delete data, or create new accounts in the context allowed by the user’s rights.\nPlease see the MSRC Blog Entry for important information about steps you can take to protect your system from this vulnerability.","summary":"Windows Support Diagnostic Tool (MSDT) can be triggered via the ms-msdt URL protocol from an application such as Word, so a malicious document can launch it. An attacker who succeeds runs code with the privileges of the calling application, which is the Follina attack.","severity":"critical","cvss":9.3,"epss":0.99163,"exploited":true,"exploited_at":"2022-06-14T00:00:00+00:00","products":[{"name":"Microsoft Windows","fixed":[],"affected":"","ecosystem":"vendor"},{"name":"microsoft windows 10 1507","fixed":["10.0.10240.19325"],"affected":"< 10.0.10240.19325","ecosystem":"vendor"},{"name":"microsoft windows 10 1607","fixed":["10.0.14393.5192"],"affected":"< 10.0.14393.5192","ecosystem":"vendor"},{"name":"microsoft windows 10 1809","fixed":["10.0.17763.3046"],"affected":"< 10.0.17763.3046","ecosystem":"vendor"},{"name":"microsoft windows 10 20h2","fixed":["10.0.19042.1766"],"affected":"< 10.0.19042.1766","ecosystem":"vendor"},{"name":"microsoft windows 10 21h1","fixed":["10.0.19043.1766"],"affected":"< 10.0.19043.1766","ecosystem":"vendor"},{"name":"microsoft windows 10 21h2","fixed":["10.0.19044.1766"],"affected":"< 10.0.19044.1766","ecosystem":"vendor"},{"name":"microsoft windows 11 21h2","fixed":["10.0.22000.739"],"affected":"< 10.0.22000.739","ecosystem":"vendor"},{"name":"microsoft windows 7","fixed":[],"affected":"","ecosystem":"vendor"},{"name":"microsoft windows 8.1","fixed":[],"affected":"","ecosystem":"vendor"},{"name":"microsoft windows rt 8.1","fixed":[],"affected":"","ecosystem":"vendor"},{"name":"microsoft windows server 2008","fixed":[],"affected":"= r2","ecosystem":"vendor"},{"name":"microsoft windows server 2012","fixed":[],"affected":"","ecosystem":"vendor"},{"name":"microsoft windows server 2012","fixed":[],"affected":"= r2","ecosystem":"vendor"},{"name":"microsoft windows server 2016","fixed":["10.0.14393.5192"],"affected":"< 10.0.14393.5192","ecosystem":"vendor"},{"name":"microsoft windows server 2019","fixed":["10.0.17763.3046"],"affected":"< 10.0.17763.3046","ecosystem":"vendor"},{"name":"microsoft windows server 2022","fixed":["10.0.20348.770"],"affected":"< 10.0.20348.770","ecosystem":"vendor"},{"name":"microsoft windows server 20h2","fixed":["10.0.19042.1766"],"affected":"< 10.0.19042.1766","ecosystem":"vendor"}],"ecosystems":["vendor"],"tags":["exploited","infrastructure","microsoft-office","ransomware","windows","word"],"not_affected_if":["patched-windows"],"how_to_check":null,"fix":"Apply the Microsoft update for CVE-2022-30190 per vendor instructions (CISA required action); exact KB and build numbers are not in the sources.","status":"open","published_at":"2022-06-01T20:15:07+00:00","first_seen_at":"2026-10-23T19:11:52+00:00","triaged_at":"2026-10-23T21:12:32+00:00","updated_at":"2026-10-23T22:29:04+00:00","category":"infrastructure","confidence":0.8,"triage":{"at":"2026-10-23T21:12:32Z","model":"claude-haiku-5-5","output":{"fix":"Apply the Microsoft update for CVE-2022-30190 per vendor instructions (CISA required action); exact KB and build numbers are not in the sources.","reach":"internet","impact":"high","summary":"Windows Support Diagnostic Tool (MSDT) can be triggered via the ms-msdt URL protocol from an application such as Word, so a malicious document can launch it.
