An attacker who successfully exploited this vulnerability could inject code into a CAB file without invalidating the file's signature.\nTo exploit the vulnerability, an attacker could modify a signed CAB file and inject malicious code. The attacker could then convince a target user to execute the file.\nThe update addresses the vulnerability by correcting how Windows validates file signatures.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:N","score":5.5},"cwes":["CWE-354"],"references":["https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2019-1163","https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2019-1163"],"products":["microsoft:windows_10","microsoft:windows_server_2016","microsoft:windows_server_2019"],"source":"nvd","synced_at":"2026-10-19T20:58:11.797917892+00:00"},"epss":{"cve":"CVE-2019-1163","score":0.01485,"percentile":0.74011,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
