# This file is used to allow custom checks and exclusions for the transactional
|
|
# variable rules. Place rules in this file so that you may influence what happens
|
|
# in the 49 - Enforcement File.
|
|
|
|
# In previous ModSecurity rules, the TARGET list would have to be updated in
|
|
# order to exclude a specific paramater like this -
|
|
#
|
|
# SecRule ARGS_NAMES|ARGS|!ARGS:foo
|
|
#
|
|
# With the new transactional variable rules, parameter exceptions can now
|
|
# be handled AFTER the initial inspection as the rules now use setvars to
|
|
# capture meta-data with each rule match. They use this syntax -
|
|
#
|
|
# setvar:tx.%{rule.id}-WEB_ATTACK/SQL_INJECTION-%{matched_var_name}=%{matched_var}
|
|
#
|
|
# When the transactional rules trigger, they will set a TX variable similar to this
|
|
# for an SQL Injection attack -
|
|
#
|
|
# Set variable "tx.950001-WEB_ATTACK/SQL_INJECTION-ARGS:comments" to "1' or select * from users where username = admin ".
|
|
#
|
|
# With this data now available, the user can implement flexible exceptions.
|
|
#
|
|
# Exception example - exclude a parameter
|
|
#
|
|
# In this example, we are inspecting
|
|
# the TX collections to see if there is a current variable that has matched
|
|
# for the 950001 SQL Injection rule ID and for the "comments" parameter. If
|
|
# so, then we are going to remove the collection entirely by using the
|
|
# setvar:!tx. syntax. By doing this, the TX collection is removed before final
|
|
# inspection at the end of phase 2 in the enforcement file.
|
|
#
|
|
#SecRule TX:'/^950001.*ARGS:comments/' ".*" "chain,phase:2,t:none,nolog,pass"
|
|
# SecRule MATCHED_VAR_NAME "TX\:(.*)" "capture,t:none,setvar:!tx.%{tx.1},setvar:tx.anomaly_score=-20"
|
|
|
|
#
|
|
# This is an example exclusion for the entire SQL Injection category of rules
|
|
#
|
|
#SecRule TX:'/SQL_INJECTION/' ".*" "phase:2,t:none,nolog,pass,chain,setvar:tx.sql_injection=+1,setvar:tx.sql_injection_%{tx.sql_injection}=%{matched_var_name}"
|
|
# SecRule TX:'/^SQL_INJECTION_/' "TX\:(.*)" "capture,t:none,setvar:!tx.%{tx.1},setvar:tx.anomaly_score=-20"
|
|
|
|
#
|
|
# This is an example exclusion that combines the URL and parameter and removes
|
|
# a specific SQL Injection ID only if the parameter foo payload matches
|
|
#
|
|
#SecRule REQUEST_FILENAME "@streq /path/to/file.php" "chain,phase:2,t:none,nolog,pass"
|
|
# SecRule TX:'/^950001.*ARGS:foo/' "@streq Item 1=1" "chain,t:none"
|
|
# SecRule MATCHED_VAR_NAME "TX\:(.*)" "capture,t:none,setvar:!tx.%{tx.1},setvar:tx.anomaly_score=-20"
