Hi me5382 natelott 👋

In both of your payloads, you're using 0.0.0.0 as the IP address. This would work if the Wildcard Cycles application was running locally on the Kali Desktop. However, as this is running on a different host, you'll need to specify the Kali IP address, not 0.0.0.0.

NyePriorThanks for the reply.  I also tried this method. I used ip address from ifconfig, local host (127.0.0.1), and 0.0.0.0 got the same result.  If that were the case, how am I able to open the js file in the browser using http://0.0.0.0:8080/script.js url?  The JS is executing when I expose the vulnerability and I can see the request happen in netcat...  Therefore I feel confident that the issue is inside the js file or with the /admin/token itself.  I have tried the python method and the netcat method.   The /admin/token endpoint gets me a 302 permanent redirect.  As a python full stack developer w/ a good understanding of accessing local host as a local web server... I think I'm missing something else or not understanding the flow completely.
