What is CVE-2025-8069?
CVE-2025-8069 is a high-severity vulnerability in AWS Client VPN, published on 23 Jul 2025. It can only be exploited from the same machine or local network, with no action from the victim.
Official description
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.
