Windows File Signature Security Feature Bypass Vulnerability

Published Aug 14, 2019 CVSS 3.1 · 5.5 Medium EPSS 1.5% KEV · Not listed
Description
A security feature bypass exists when Windows incorrectly validates CAB file signatures. An attacker who successfully exploited this vulnerability could inject code into a CAB file without invalidating the file's signature.
To 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.
The update addresses the vulnerability by correcting how Windows validates file signatures.
