Important: Remote Code Execution CVE-2017-12617

When running with HTTP PUTs enabled (e.g. via setting the readonly initialisation parameter of the Default servlet to false) it was possible to upload a JSP file to the server via a specially crafted request. This JSP could then be requested and any code it contained would be executed by the server.

This was fixed in revisions 1809669, 1809674, 1809684 and 1809711.

This issue was first reported publicly followed by multiple reports to the Apache Tomcat Security Team on 20 September 2017.
