The version of Apache Tomcat installed on the remote host is 8.5.0 to 8.5.75 or 9.0.0.M1 to 9.0.20. It is, therefore, affected by a request mix-up vulnerability. If a web application sends a WebSocket message concurrently with the WebSocket connection closing, it is possible that the application will continue to use the socket after it has been closed. The error handling triggered in this case could cause the a pooled object to be placed in the pool twice. This could result in subsequent connections using the same object concurrently which could result in data being returned to the wrong use and/or other errors.
Note that the scanner has not attempted to exploit these issues but has instead relied only on the application’s self-reported version number.Read More
