Hello Christian and team, Having recently tried out ModSecurity, it appears that lower paranoia levels (Basic, PL1, PL2, PL3) are not fully blocking all flavors of XSS and SQL injection.
Encoded XSS attacks are bypassing the CRS rules. Example below: http://localhost:8082/xss2?uid=%3Balert%281%29%3B Similarly for SQLi, the below pattern is getting through. http://localhost:8082/sqli2?uid=3-2 When the Paranoia Level is set to PL4, the encoded XSS attack is blocked, however it crashes the application. With PL4, SQLi attack reported by the vulnerability scanner above, is still not blocked. Is it possible to selectively add custom rules (for encoded XSS attacks) to the basic level or other lower levels that do not adversely impact the application? Thanks.

We want to learn about you and how you use CRS in your setups - and we want to talk with you about the road map for the project and various feature requests. The date is the night before AppSecEU. So you can join this get-together on Wednesday and then attend AppSec EU on Thursday / Friday. Please do consider to join us when Chaim, Walter and I meet for the first time face2face. :) Best, Christian -- https://www.feistyduck.com/training/modsecurity-training-course<https://isolate.menlosecurity.com/1/3735928037/https:/www.feistyduck.com/training/modsecurity-training-course> https://www.feistyduck.com/books/modsecurity-handbook/<https://isolate.menlosecurity.com/1/3735928037/https:/www.feistyduck.com/books/modsecurity-handbook/> mailto:christian.fol...@netnea.com<mailto:christian.fol...@netnea.com> twitter: @ChrFolini _______________________________________________ Owasp-modsecurity-core-rule-set mailing list Owasp-modsecurity-core-rule-set@lists.owasp.org<mailto:Owasp-modsecurity-core-rule-set@lists.owasp.org> https://lists.owasp.org/mailman/listinfo/owasp-modsecurity-core-rule-set<https://isolate.menlosecurity.com/1/3735928037/https:/lists.owasp.org/mailman/listinfo/owasp-modsecurity-core-rule-set> American Express made the following annotations ****************************************************************************** "This message and any attachments are solely for the intended recipient and may contain confidential or privileged information.
