Opps.. early <enter>.. To find out more about that preprocessor, check the source code, under docs.. you'll see README.http_inspect. Search for Chunk and you get * chunk_length [non-zero positive integer] * This option is an anomaly detector for abnormally large chunk sizes. This picks up the apache chunk encoding exploits, and may also alert on HTTP tunneling that uses chunk encoding. Anyways.. the readme explains what the config options are for and how you might be able to tweak it better. On Tue, May 7, 2013 at 5:29 PM, Jeremy Hoel <jthoel () gmail com> wrote:
This is GID 120, SID 8. So it's not a rule as in snort.rules This gets fired from preprocessor http_inspect On Tue, May 7, 2013 at 5:24 PM, Josh Bitto <jbitto () onlineschool ca> wrote:I'm having a bit of a problem fully grasping how to search up rules that have been fired..... 2013-05-07T10:14:05-07:00 firewall snort[62223]: [120:8:1] (http_inspect) INVALID CONTENT-LENGTH OR CHUNK SIZE [Classification: Unknown Traffic] [Priority: 3] {TCP} 209.97.200.53:32459 -> 216.178.47.38:80 Ok so what I understand from the log is that rule 120 fired. Either I need some caffeine or it's a horrible Tuesday for me to comprehend this, but I'm just not getting it. The instructions on how to search for the group id and the sid for some reason are not sticking. Can someone dumb this down for me....I'm gonna run out and get a pop and hopefully come back to someone who has awesomely helped me out. Basically I want to be able to search for explanations on whatever event happens so I can determine if I need to take action or not.
