Summary
Lack of SSL/TLS certificate and hostname validation in Amazon EC2 Plugin
Details

Amazon EC2 Plugin connects to Windows agents via HTTPS.

Amazon EC2 Plugin 1.50.1 and earlier unconditionally accepts self-signed HTTPS certificates and does not perform hostname validation when connecting to Windows agents. This lack of validation could be abused using a man-in-the-middle attack to intercept these connections to build agents.

Amazon EC2 Plugin 1.50.2 by default no longer accepts self-signed HTTPS certificates and performs hostname validation. A new configuration option allows restoring the previous, unsafe behavior. For more information see the plugin documentation.

Severity
5.6 (Medium)
