Nice.
Hi Team
Am able to get C**** and password and loggedin …then i tried to upload a php reverse shell but dont know how to execute it …am I on the right path? how to execute this script?
The other thread seems not working anymore… I am trying to solve the retired machine. I have what looks like the username and the password of the web but I get a 422 “The change you requested was rejected” error when trying to login, no matter if I use a good login or a bad one…
Someone with the same problem?
Thanks!
