I was resolving the challenges of LFI to RCE and i found the first challenge:
"Using the LFI to RCE vulnerability run the command 'uname -a'. Submit just the Linux Kernel version number as your answer (i.e. Debian 3.19.42-2)"
i achieved execute the command, but when a submit, i get a error
I tried submit only "4.19.171-2" and Debian too
