Description

A flaw was found in Spring Boot. When configured to use an SSL (Secure Sockets Layer) bundle, the Elasticsearch auto-configuration component does not perform hostname verification when establishing a connection to the Elasticsearch server. An attacker on an adjacent network could exploit this by performing a man-in-the-middle attack. This could lead to the disclosure or modification of sensitive information exchanged between Spring Boot and the Elasticsearch server.
