Note: The issue below was fixed in Apache Tomcat 7.0.80 but the release vote for the 7.0.81 release candidate did not pass. Therefore, although users must download 7.0.81 to obtain a version that includes the fix for this issue, version 7.0.80 is not included in the list of affected versions.

When running 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.

This was fixed in revisions 1804604 and 1804729.

This issue was reported responsibly to the Apache Tomcat Security Team by iswin from 360-sg-lab (360观星实验室) on 26 July 2017 and made public on 19 September 2017.

Affects: 7.0.0 to 7.0.79
