out of the b0x 😉
downloaded a router online config apk , run it on LD Player and activated burp suite .
checking the request :
sent it to repeater and ..
response got a filter
changed a bit in it and play again and i was able to remote command ! next i was thinking to get reverse shell and all failed ( i guess due to iptables )
this graps my attention
so did my key (ssh-keygen) locally and decided to inject it !
and volla !
