CVE-2025-8069 - AWS Client VPN Windows Client Local Privilege Escalation

unknownCVE-2025-8069

Scope: Amazon/AWS Content Type: Important (requires attention) Publication Date: 2025/07/23 8:30 AM PDT Description: AWS Client VPN is a managed client-based VPN service that enables secure access to AWS and on-premises resources. The AWS Client VPN client software runs on end-user devices, supporting Windows, macOS, and Linux and provides the ability for end users to establish a secure tunnel to the AWS Client VPN Service. We identified CVE-2025-###, an issue in AWS Client VPN. 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. Affected version: 4.1.0, 5.0.0, 5.0.1, 5.0.2, 5.1.0, 5.2.0, 5.2.1
