I still have a problem here. I want snort detect the following signature: POST /index.html?crap=10601855 It is in the tcp data section. How can I write a rule for it and how to set it up and run by snort?
Read the docs [0]. Read the current rules for an example.
From web-misc.rules:
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? ----- Erek Adams "When things get weird, the weird turn pro."
