Description Adam Mariš 2017-09-19 16:04:54 UTC 
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.

Affected versions: 7.0.0 to 7.0.79

Comment 10 Doran Moppert 2017-10-04 05:17:36 UTC 
Mitigation:

Ensure that readonly is set to true (the default) for the DefaultServlet, WebDAV servlet or application context.

Block HTTP methods that permit resource modification for untrusted users.
Comment 11 Doran Moppert 2017-10-04 05:19:10 UTC 
Statement:

This flaw affects Tomcat on Red Hat Enterprise Linux only when a specific context is configured with readonly=false. The default configuration has a readonly context, so it is not affected.
