ModSecurity Core Rule Set v2.2.0

(From Ryan Barnett)

I am pleased to announce the release of the OWASP ModSecurity Core Rule Set (CRS) v2.2.0. This is a significant update as we have added a number of very important capabilities.

CHANGE LOG -

-------------------------- Version 2.2.0 - 05/26/2011 --------------------------

Improvements: 

Changed Licensing from GPLv2 to Apache Software License v2 (ASLv2)   http://www.apache.org/licenses/LICENSE-2.0.txt  
Created new INSTALL file outlining quick config setup - Added a new rule regression testing framework to the /util directory 
Added new activated_rules directory which will allow users to place symlinks pointing   to files they want to run.  This allows for easier Apache Include wild-carding 
Adding in new RULE_MATURITY and RULE_ACCURACY tags 
Adding in a check for X-Forwarded-For source IP when creating IP collection - Added new Application Defect checks (55 app defect file) from Watcher tool (Check Charset)    http://websecuritytool.codeplex.com/wikipage?title=Checks#charset  
Added new AppSensor rules to experimental_dir   https://www.owasp.org/index.php/AppSensor_DetectionPoints 
Added new Generic Malicious JS checks in outbound content - Added experimental IP Forensic rules to gather Client hostname/whois info  http://blog.spiderlabs.com/2010/11/detecting-malice-with-modsecurity-ip-forensics.html  
Added support for Mozilla's Content Security Policy (CSP) to the experimental_rules   http://blog.spiderlabs.com/2011/04/modsecurity-advanced-topic-of-the-week-integrating-content-security-policy-csp.html    
Global collection in the 10 file now uses the Host Request Header as the collection key.   This allows for per-site global collections. 
Added new SpiderLabs Research (SLR) rules directory (slr_rules) for known vulnerabilties.   This includes both converted web rules from Emerging Threats (ET) and from SLR Team. 
Added new SLR rule packs for known application vulns for WordPress, Joomla and phpBB 
- Added experimental rules for detecting Open Proxy Abuse   http://blog.spiderlabs.com/2011/03/detecting-malice-with-modsecurity-open-proxy-abuse.html  
Added experimental Passive Vulnerability Scanning ruleset using OSVDB and Lua API   http://blog.spiderlabs.com/2011/02/modsecurity-advanced-topic-of-the-week-passive-vulnerability-scanning-part-1-osvdb-checks.html  
Added additional URI Request Validation rule to the 20 protocol violations file (Rule ID - 981227) 
Added new SQLi detection rules (959070, 959071 and 959072) 
Added "Toata dragostea mea pentru diavola" to the malicious User-Agent data   https://www.modsecurity.org/tracker/browse/CORERULES-64  Bug Fixes: - Assigned IDs to all active SecRules/SecActions 
Removed rule inversion (!) from rule ID 960902 
Fixed false negative issue in Response Splitting Rule 
Fixed false negative issue with @validateByteRange check 
Updated the TARGETS lising for rule ID 950908 
Updated TX data for REQBODY processing 
Changed the pass action to block in the RFI rules in the 40 generic file 
Updated RFI regex to catch IP address usage in hostname   https://www.modsecurity.org/tracker/browse/CORERULES-68 
Changed REQUEST_URI_RAW variable to REQUEST_LINE in SLR rules to allow matches on request methods. 
Updated the RFI rules in the 40 generic attacks conf file to remove explicit logging actions.   They will now inherit the settings from the SecDefaultAction
