Vanilla PHP based application containing the challenge of taking over Web Application via Shell Upload (vulnerable file upload feature) (docker image & documentation will be available at: https://pentestlabs.gitbook.io/challenges/)
The challenge can be deployed with the following one liner:
docker run -it --rm uexpl0it/web-application-takeover
You can find me @syed__umar and the challenges @ PentestLabs. The challenge was inspired by OWASP SKF and I'll be creating more like these in the near future, stay tuned!
Also, thanks to everyone who did the challenges previously, especially @makman for helping me through the PHP code, @dodain for suggestions in the previous challenge & to obnoxious-spirit for DockerFile's improvements.
