Description of the vulnerability

The Apache Tomcat product includes an HTTP server.

In HTTP 1.1, the client may send several requests without waiting for the response to the first request. However, in some cases, the server mismatches the response body and the request, in such a way that a client may receive the response for another request. This vulnerability looks like the one described in VIGILANCE-VUL-21355.

An attacker can therefore send a burst of HTTP 1.1 request to Apache Tomcat, in order to get sensitive information.
