Detailsinfo

A vulnerability was found in Apache TomEE up to 10.0.0-M0/10.2.0/11.0.0-M1. It has been rated as critical. This issue affects some unknown processing of the component Embedded HTTP Server. The manipulation with an unknown input leads to a privileges management vulnerability. Using CWE to declare the problem leads to CWE-269. The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

The embedded HTTP server does not clear the security identity established during a request before its worker thread handles the next request. A remote unauthenticated attacker can have their request processed with the identity of a previously authenticated user, gaining that user's privileges. Only applications served by the embedded HTTP server that authenticate programmatically or via basic authentication 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.
