CVE-2017-12615: Apache Tomcat on Windows Remote Code Execution Vulnerability

High severity, CVSS 8.1. Actively exploited: in CISA KEV since 2022-03-25. EPSS: 99.6% chance of exploitation in the next 30 days.

When running Apache Tomcat 7.0.0 to 7.0.79 on Windows with HTTP PUTs enabled (e.g. via setting the readonly initialisation parameter of the Default 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.
