Hi,
I have some signatures as example:
alert tcp $EXTERNAL_NET any -> $HTTP_SERVERS $HTTP_PORTS (msg:"WEB- FRONTPAGE _vti_inf.html access"; flow:to_server,established; uricontent:"/_vti_inf.html"; nocase; reference:nessus,11455; classtype:web-application-activity; sid:990; rev:9;)
This signature generated some alerts.But the packets that had generated the alert don't have payload, they only have a ip and tcp header. How can this packet generate alert without having the uricontent "/_vi_inf.html" specified in the signature ?
Obs: I'm using the database output plugin, like this:output database: alert, mysql, user=root dbname=snort host=cirene,detail=full
this output log all the packet, including payload
