Greetings everyone,
I am pleased to announce the release of the OWASP ModSecurity Core Rule Set (CRS) v2.0.9.
The most significant change is that users can now easily toggle between Traditional or Anomaly Scoring Detection modes.
CHANGE LOG -
--------------------------
Version 2.0.9 - 11/17/2010
--------------------------
Improvements:
- Changed the name of the main config file to modsecurity_crs_10_config.conf.example so that
it will not overwrite existing config settings. Users should rename this file to activate it.
- Traditional detection mode is now the current default
- Users can now more easily toggle between traditional/standard mode vs. anomaly scoring mode
by editing the modsecurity_crs_10_config.conf file
- Updated the disruptive actions in most rules to use "block" action instead of "pass". This
is to allow for the toggling between traditional vs. anomaly scoring modes.
- Removed logging actions from most rules so that it can be controlled from the SecDefaultAction
setting in the modsecurity_crs_10_config.conf file
- Updated the anomaly scores in the modsecurity_crs_10_config.conf file to more closely match
what is used in the PHPIDS rules. These still have the same factor of severity even though
the numbers themselves are smaller.
- Updated the 49 and 59 blocking rules to include the matched logdata
- Updated the TAG data to further classify attack/vuln categories.
- Updated the SQL Injection filters to detect more boolean logic attacks
- Moved some files to optional_rules directory (phpids, Emerging Threats rules)
Bug Fixes:
- Fixed Rule ID 960023 in optional_rules/modsecurity_crs_40_experimental.conf is missing 1 single quote
https://www.modsecurity.org/tracker/browse/CORERULES-63
- Moved all skipAfter actions in chained rules to the rule starter line (must have ModSec v2.5.13 or higher)
https://www.modsecurity.org/tracker/browse/MODSEC-159
- Fixed restricted file extension bug with macro expansion
https://www.modsecurity.org/tracker/browse/CORERULES-60
- Updated the SQLI TX variable macro expansion data in the 49 and 60 files so that
it matches what is being set in the sql injection conf file
- Fixed typo in SQL Injection regexs - missing backslash for word boundary (\b)
