CVE-2025-8069

SYSTEM code execution via unsecured OpenSSL configuration

Published Jul 23, 2025 · Updated Oct 14, 2025

Privilege escalation in AWS Client VPN 4.1.0 and 5.0.0 through 5.2.1 on Windows allows local users to execute code as SYSTEM. The installer loads an OpenSSL configuration file from C:\usr\local\windows-x86_64-openssl-localbuild\ssl, where non-admin users can plant executable configuration. Exploitation requires an administrator to start the client installation after the file is planted; Linux and macOS clients are unaffected.
