CVE-2025-8069: Aws Client VPN

High severity, CVSS 7.8. EPSS: 0.2% chance of exploitation in the next 30 days.

During the AWS Client VPN client installation on Windows devices, the install process references the C:\usr\local\windows-x86_64-openssl-localbuild\ssl directory location to fetch the OpenSSL configuration file. As a result, a non-admin user could place arbitrary code in the configuration file. If an admin user starts the AWS Client VPN client installation process, that code could be executed with root-level privileges. This issue does not affect Linux or Mac devices. We recommend users discontinue any new installations of AWS Client VPN on Windows prior to version 5.2.2.

Affected products

• Aws Client VPN: version 4.1.0 only; from 5.0.0, before 5.2.2 (fixed in 5.2.2)
