Mod Security Causing ADMIN-AJAX.PHP 403 Errors

harvey

Hi, I started getting 403 errors from admin-ajax.php, and I traced it down to Mod Security. When I disable mod security, the error goes away.

I installed the OWASP rules pack.

Are the any specific rules I need to use to prevent this?

Thanks!

I just noticed that Cyberpanel doesn't include the OWASP WordPress rules that were added in v3.0 as found here:

https://github.com/SpiderLabs/owasp-modsecurity-crs/blob/v3.0/master/rules/REQUEST-903.9002-WORDPRESS-EXCLUSION-RULES.conf

Is there a reason these rules weren't added? Can I add them manually, or willl you add them in an update?

Thanks!

CP comes with basic rules after that you need to manage yourself

Thank you. If I want to add the WordPress rules I linked to above, where should I put the file?

Mod sec is a openlitespeed config so follow

As a guess it would be the same process
