Отчет
This Moderate severity flaw in Apache Tomcat's WebSocket chat example could lead to a denial of service. The impact is limited as the vulnerable component is part of an example application, which is generally not deployed in production environments. Exploitation requires the example application to be present and accessible.
Меры по смягчению последствий
To mitigate this vulnerability, remove the examples web application from your Apache Tomcat installation. This can typically be achieved by deleting the examples directory or examples.war file from the webapps directory of your Tomcat installation. A restart of the Tomcat service may be required for the changes to take full effect.
