After doing some logfile analysis briefly yesterday, I noticed what seems
to be some form of bot, worm, something, searching for what could seems to
point to a Cisco exploitation of sorts. (http://tinyurl.com/df9d8)
All the hosts who've tried searching for the string are coming from APNIC.
So I'm wondering... Has someone taken Michael Lynn's paper "Holy Grail"
and produced a "DaVinci Code" to exploit the flaws Lynn spoke of...
Code snippet below is of "cisco_scanner.c" which searches for the same
particular /level/16/exec/-///pwd string however the code can be modified
(obviously) and a search turns up less than one page of results on Google.
Author's page seems to be gone like the wind... Anyhow.
# grep "/level/16/exec/-///" access_log |awk '{print $1,"\t\t"$7}'
58.236.50.75 /level/16/exec/-///pwd
221.141.168.137 /level/16/exec/-///pwd
221.138.93.31 /level/16/exec/-///pwd
218.53.244.16 /level/16/exec/-///pwd
222.232.84.34 /level/16/exec/-///pwd
222.238.128.14 /level/16/exec/-///pwd
218.50.74.189 /level/16/exec/-///pwd
218.239.26.42 /level/16/exec/-///pwd
218.232.83.18 /level/16/exec/-///pwd
211.208.254.67 /level/16/exec/-///pwd
whois.apnic.net $ABOVE_HOSTS
Code snippet...
/*
Multi-thread Cisco HTTP vulnerable scanner v0.2
by Inode
*/
#define HTTP_REQUEST "GET /level/16/exec/-///pwd HTTP/1.0\n\n"
So now I have yet another mod_security rule added ;)
SecFilterSelective THE_REQUEST "/level/16" "redirect:http://www.cisco.com"

It is much easier to suggest solutions when you know nothing
about the problem. -- Niklaus Wirth
