#
# Cisco IOS Connectback shellcode v1.0
# (c) 2007 IRM Plc
# By Gyan Chawdhary
#
# ----------------------------------------------------------------------------------------
#
# The code creates a new TTY, allocates a shell with privilege level 15 and connects back
# on port 21
#
# This shellcode can be used as the payload for any IOS exploit on a PowerPC-based device.
#
#
# The following five hard-coded addresses must be located for the target IOS version.
#
# The hard-coded addresses used here are for:
#
# IOS (tm) C2600 Software (C2600-IK9S-M), Version 12.3(22), RELEASE SOFTWARE (fc2)
