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) 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
