RE: DOUBLE DECODING ATTACK

You use threshold.conf to disable these preprocessor alerts. 

suppress gen_id 119, sig_id 2     #  disable http_inspect: DOUBLE
DECODING ATTACK  alerts

Make sure that threshold.conf is enabled in your snort.conf.

Subject: [Snort-users] DOUBLE DECODING ATTACK


hi snorters 

i run snort 2.3.2 on solaris 9 
in the logs i see  a lot of entries
with text: DOUBLE DECODING ATTACK

nearly all of the entries are generated 
by the source ip-adress of my proxy. 

so i assume, i didn't setup snort correctly.

in snort.conf i did define variable HOME_NET
and also var EXTERNAL_NET !$HOME_NET 
HOME_NET is defined as super-net of 8 c-class ( /21 ) 
where proxy-ip is included.

i start snort with option -h and my network.

or is there a way to disable this rule ? 

best regards 
hans
