Description
The embedded OpenEJB HTTP server does not isolate HTTP sessions between web applications. A remote attacker can use a session established in one web application in another one, which then trusts session state set by the first application. Only deployments hosting several web applications on the embedded HTTP server are affected. Users are recommended to block network access to the embedded HTTP server from untrusted clients, or to migrate to the Tomcat based TomEE distributions.
