# Script to post a payload against a local webserver at each paranoia level.
#
# Note: Webserver has to be prepared to take desired PL as Request Header "PL".
#
# WARNING: Setting the paranoia level using a header without proper
# authentication and authorization is extremely dangerous, and is not
# recommended for production.
#
# Check how to use the Christian Folini's Apache access log format at:
# https://www.netnea.com/cms/apache-tutorial-5_extending-access-log/
#
# LogFormat "%h %{GEOIP_COUNTRY_CODE}e %u [%{%Y-%m-%d %H:%M:%S}t.%{usec_frac}t] \"%r\" %>s %b \
# \"%{Referer}i\" \"%{User-Agent}i\" \"%{Content-Type}i\" %{remote}p %v %A %p %R \
# %{BALANCER_WORKER_ROUTE}e %X \"%{cookie}n\" %{UNIQUE_ID}e %{SSL_PROTOCOL}x %{SSL_CIPHER}x \
# %I %O %{ratio}n%% %D %{ModSecTimeIn}e %{ApplicationTime}e %{ModSecTimeOut}e \
# %{ModSecAnomalyScoreInPLs}e %{ModSecAnomalyScoreOutPLs}e \
# %{ModSecAnomalyScoreIn}e %{ModSecAnomalyScoreOut}e" extended
#
# This script assumes %{ModSecAnomalyScoreIn}e is the column before to last in
# the access log, if this does not match your LogFormat the script won't work
# For better results set the SecDefaultAction to 'pass'.
#
# The anomaly score envvar can be set as follows:
# SecAction "id:90101,phase:5,pass,nolog,\
#     setenv:ModSecAnomalyScoreIn=%{TX.anomaly_score}"
#
# Sample rule to setup the PL dynamically from localhost"
