CX: CVE-2021-30639 in Maven-org.apache.tomcat:tomcat-coyote and 9.0.22 @ JavaVulnerableLab-1.refs/heads/master

Description

A vulnerability in Apache Tomcat allows an attacker to remotely trigger a denial of service. An error introduced as part of a change to improve error handling during non-blocking I/O meant that the error flag associated with the Request object was not reset between requests. This meant that once a non-blocking I/O error occurred, all future requests handled by that request object would fail. Users were able to trigger non-blocking I/O errors, e.g. by dropping a connection, thereby creating the possibility of triggering a DoS. Applications that do not use non-blocking I/O are not exposed to this vulnerability. This issue affects Apache Tomcat 7.0.X, 8.0.X, 8.5.X before 8.5.65, 9.0.X before 9.0.45 and 10.0.X before 10.0.5.
