Announcing Release of OWASP ModSecurity Core Rule Set v2.2.0

--------------------------

The ModSecurity Development Team is pleased to announce the release of the OWASP ModSecurity Core Rule Set v.2.20. There are many significant improvements as listed below from the CHANGES file.

--------------------------

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)

- 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

- 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

- 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
