An attacker who successfully exploited the vulnerability could use the sandbox escape to elevate privileges on an affected system.\nTo exploit the vulnerability, an attacker would first have to log on to the system, and then run a specially crafted application to take control over the affected system.\nThe security update addresses the vulnerability by preventing sandboxed processes from creating reparse points targeting inaccessible files.","published_at":"2019-08-14T20:55:03Z","last_modified_at":null,"cvss_v3_score":7.9,"cvss_v3_vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:L/A:L/E:P/RL:O/RC:C","cvss_v3_severity":"HIGH","cvss_v4_score":null,"cvss_v4_vector":null,"cvss_v4_severity":null,"ssvc_decision":null,"ssvc_exploitation":null,"ssvc_automatable":null,"ssvc_technical_impact":null,"cwes":null,"nvd_references":["https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2019-1170","http://packetstormsecurity.com/files/154192/Microsoft-Windows-SET_REPARSE_POINT_EX-Mount-Point-Security-Feature-Bypass.html"],"vuln_status":null,"trending_score":null,"is_trending":false,"has_trended":false,"trended_number_one":false,"trending_peak_score":null,"trending_peak_rank":null,"started_trending_at":null,"trended_number_one_at":null,"summary_generated":null,"summary_generated_at":null,"summary_model":null,"created_at":"2026-06-24T00:09:39.878444Z","updated_at":"2026-06-28T23:11:58.803949Z"},"effective_severity":"HIGH","badges":[],"impact_analysis":[],"cvss_v3_decoded":{"version":"3.1","metrics":[{"metric":"AV","name":"Attack Vector","value":"L","value_label":"Local"},{"metric":"AC","name":"Attack Complexity","value":"L","value_label":"Low"},{"metric":"PR","name":"Privileges Required","value":"L","value_label":"Low"},{"metric":"UI","name":"User Interaction","value":"N","value_label":"None"},{"metric":"S","name":"Scope","value":"C","value_label":"Changed"},{"metric":"C","name":"Confidentiality","value":"H","value_label":"High"},{"metric":"I","name":"Integrity","value":"L","value_label":"Low"},{"metric":"A","name":"Availability","value":"L","value_label":"Low"},{"metric":"E","name":"E","value":"P","value_label":"Physical"},{"metric":"RL","name":"RL","value":"O","value_label":"O"},{"metric":"RC","name":"RC","value":"C","value_label":"Changed"}]},"cvss_v4_decoded":{"version":null,"metrics":[]},"affected":[{"vendor_slug":"microsoft","vendor_name":"Microsoft","product_slug":"windows-10","product_name":"Windows 10","version_start":"1903","version_start_inclusive":true,"version_end":"1903","version_end_inclusive":true,"cpe23_uri":"cpe:2.3:o:microsoft:windows_10:1903:*:*:*:*:*:*:*"},{"vendor_slug":"microsoft","vendor_name":"Microsoft","product_slug":"windows-10-1809","product_name":"windows_10_1809","version_start":null,"version_start_inclusive":null,"version_end":null,"version_end_inclusive":null,"cpe23_uri":"cpe:2.3:o:microsoft:windows_10_1809:*:*:*:*:*:*:x86:*"},{"vendor_slug":"microsoft","vendor_name":"Microsoft","product_slug":"windows-10-1809","product_name":"windows_10_1809","version_start":null,"version_start_inclusive":null,"version_end":null,"version_end_inclusive":null,"cpe23_uri":"cpe:2.3:o:microsoft:windows_10_1809:*:*:*:*:*:*:x64:*"},{"vendor_slug":"microsoft","vendor_name":"Microsoft","product_slug":"windows-10-1809","product_name":"windows_10_1809","version_start":null,"version_start_inclusive":null,"version_end":null,"version_end_inclusive":null,"cpe23_uri":"cpe:2.3:o:microsoft:windows_10_1809:*:*:*:*:*:*:arm64:*"},{"vendor_slug":"microsoft","vendor_name":"Microsoft","product_slug":"windows-server-1903","product_name":"windows_server_1903","version_start":null,"version_start_inclusive":null,"version_end":null,"version_end_inclusive":null,"cpe23_uri":"cpe:2.3:o:microsoft:windows_server_1903:*:*:*:*:*:*:*:*"},{"vendor_slug":"microsoft","vendor_name":"Microsoft","product_slug":"windows-server-2019","product_name":"Windows Server 2019","version_start":null,"version_start_inclusive":null,"version_end":null,"version_end_inclusive":null,"cpe23_uri":"cpe:2.3:o:microsoft:windows_server_2019:*:*:*:*:*:*:*:*"}],"exploit_refs":[],"news":[],"references":[{"url":"https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2019-1170","source_type":"VENDOR_ADVISORY","tags":["advisory"]},{"url":"http://packetstormsecurity.com/files/154192/Microsoft-Windows-SET_REPARSE_POINT_EX-Mount-Point-Security-Feature-Bypass.html","source_type":"EXPLOIT","tags":["exploit"]}],"timeline":[{"type":"published","at":"2019-08-14T20:55:03Z","label":"CVE published","source":null},{"type":"cvss_changed","at":"2026-06-28T17:00:19.386120Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:00:19.386120Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:00:19.386120Z","label":"CVSS score revised","source":"cvelistv5"}]}
