Unable to configure WAF for all paths

[rk9qn3j]

Hi,

I'm currently trying to configure the WAF to apply to all paths (/*) for an app, but always seems to end up in faulty configuration, only protecting a specific path (SecRule) or the below error message.

Configuration:

apiVersion: traefik.io/v1alpha1
kind: Middleware
metadata:
  name: traefik-mw-waf
  namespace: traefik
spec:
  plugin:
    coraza:
      directives:
      - SecRuleEngine On
      - SecDebugLog /dev/stdout
      - SecDebugLogLevel 9
      - Include @owasp_crs/**.conf
      - Include @crs-setup.conf.example

Results in:

traefik-87ff6ff56-cfh7k traefik 2024-06-04T19:38:09Z ERR [client "xxx.xx.xx.xxx"] Coraza: Access denied (phase 1). ModSecurity CRS is deployed without configuration!

I would be grateful for some guidance with this! 🙏

Try - Include @crs-setup.conf.example before the - Include @owasp_crs/**.conf

Changing places on - Include @owasp_crs/**.conf and - Include @crs-setup.conf.example removes the error message but doesn't seem to process any of the incoming requests at all (no logs generated by the plugin), but if I add - SecRule REQUEST_URI "@streq /test" "id:101,phase:1,log,deny,status:403" and try to access that path, I can clearly see that it's being denied by the plugin:

@rk9qn3j try this:

apiVersion: traefik.io/v1alpha1
kind: Middleware
metadata:
  name: traefik-mw-waf
  namespace: traefik
spec:
  plugin:
    coraza:
      directives:
      - SecRuleEngine On
      - SecDebugLog /dev/stdout
      - SecDebugLogLevel 9
      - Include @crs-setup.conf.example
      - Include @owasp_crs/**.conf

When you load - Include @crs-setup.conf.example after - SecRuleEngine On you are overriding the value to DetectionOnly.

I have tried that, tried to place - SecRuleEngine On after - Include @crs-setup.conf.example and as the last entry, but unfortunately, it doesn't make any difference.. 😐
