So this is an odd issue.
python script.py -a 1234 works
/usr/bin/python /tmp/script.py -a 1234 works
nc 127.0.0.1 443 -e /bin/bash works
nc 127.0.0.1 443 -e /usr/bin/python /tmp/script.py -a 1234 fails with all-A-records NIY
nc 127.0.0.1 443 -e "/usr/bin/python /tmp/script.py -a 1234" fails with failed : No such file or directory
Am I missing something here? I'm not sure why this isn't working.
Okay I'm not sure what's up with netcat but doing an old fashion bash reverse shell works just fine and solves the problem.
/usr/bin/python -u /tmp/script.py >& /dev/tcp/127.0.0.1/443 0>&1
A quick note here, make sure you include the -u otherwise you'll get the incoming data from the socket but nothing output from your script will get sent back over the socket.
