  alert tcp $EXTERNAL_NET any -> $HOME_NET $HTTP_PORTS (msg:"WEB-MISC
  globals.pl access"; flow:to_server,established;
  uricontent:"/globals.pl";  reference:cve,CVE-2001-0330;
  reference:bugtraq,2671; classtype:web-application-activity;
  sid:2073; rev:1;)

So modify that to work for your need.

    alert tcp $EXTERNAL_NET any -> $HOME_NET $HTTP_PORTS (msg:"WEB-MISC
    crap=10601855 access";  flow:to_server,established;
    uricontent:"/index.html?crap=10601855"; sid:1000001; rev:1;)

Not too hard is it?


It still didn't work. But I can see that tcpdump can record this
traffic.

I also tried all the following rules are not working:

alert tcp any any -> any any (msg:"WEB-MISC 0 crap=10601855 access ";
flow:to_server,established; uricontent:"/index.html?crap="; sid:1000001;
rev:1;)

alert tcp $EXTERNAL_NET any -> $HOME_NET $HTTP_PORTS (msg:"WEB-MISC 1
crap=10601855 access "; flow:to_server,established;
uricontent:"/index.html?crap="; sid:1000001; rev:1;)

alert tcp $EXTERNAL_NET $HTTP_PORTS -> $HOME_NET any (msg:"WEB-MISC 2
crap=10601855 access "; flow:to_server,established;
uricontent:"/index.html?crap="; sid:1000001; rev:1;)

I also assigned the following variable and values in snort.conf file:

var HOME_NET 192.168.1.0/24
var EXTERNAL_NET 213.190.178.0/24
var HTTP_PORTS 8888


The snort command I used is:

Snort -c /usr/local/snort.2.0.0/etc/snort.conf
