What happened?

I am trying to use a customized setup of appsec CRS rules, specifically, trying to use latest version of CoreRuleSet (since the one bundles in Crowdsec is a year old now, if not more), but I fail. There are 2 issues, and this is ticket for one of them: "unknown directive" errors when using conf files from CoreRuleSet 4.9 and 4.10 (did not test earlier versions). To be more correct a few of the errors are from crs-setup file, but even if that one is disabled - it will be failing on REQUEST-901-INITIALIZATION.conf even. Here are logs (some errors are from another issue I will raise shortly):

Comparing 901200 directive as example (since it comes from a conf file which is not customized at all, and is technically included in CrowdSec's official collection, the only differences are version and addition of tag element, but tag is available in other configs bundled with CrowdSec, so not sure if that's really the root cause.
image
On the other hand I "split" the CrowdSec's version to multiline for the sake of comparison, so maybe it does not like mutlilines?

What did you expect to happen?

Conf files to be processed normally and CrowdSec to start-up

How can we reproduce it (as minimally and precisely as possible)?

My docker-compose
All CrowdSec relate files for the container

  1. In config/crowdsec/yaml/appsec/simbiat-seclang.yaml file remove/comment the default CrowdSec config and uncomment the custom one
  2. Create container from docker-compose.yml (technically can remove GEOIP dependency)
  3. Attempt to start the container
  4. It fails to start

Anything else we need to know?

No response

Hi we will triage your issue over the following week please note their is a current bug in latest crowdsec which does happen with custom seclang rules that are multi-line #3350 (comment)

Either revert back to 1.6.3 to see if the behaviour is linked to the same issue or format your rules not to be multi-lined

looks like different symptoms, but I will be able to test a bit tomorrow. I will try removing tag, using one-line and rolling back. Will share the results, when ready.

Strange, I tried with just

name: simbiat/simbiat-seclang
seclang_rules:
  - SecRuleEngine On
  - SecRequestBodyAccess On
seclang_files_rules:
  - /corerulset/rules/REQUEST-901-INITIALIZATION.conf

and somehow got a non-descriptive error instead of one complaining about 901200

time="2025-01-01T13:15:04Z" level=warning msg="Machine is not allowed to synchronize decisions, you can enable it with `cscli console enable console_management`"
time="2025-01-01T13:15:04Z" level=error msg="crowdsec - goroutine crowdsec/StartRunSvc crashed: runtime error: invalid memory address or nil pointer dereference"
time="2025-01-01T13:15:04Z" level=error msg="please report this error to https://github.com/crowdsecurity/crowdsec/issues"
time="2025-01-01T13:15:04Z" level=error msg="stacktrace/report is written to /var/lib/crowdsec/data/trace/crowdsec-crash.1572098102.txt: please join it to your issue"
time="2025-01-01T13:15:04Z" level=fatal msg="crowdsec stopped"

So tried

name: simbiat/simbiat-seclang
seclang_files_rules:
  - 01-coraza-recommended.conf
  - 02-crs-setup.conf
  - 03-exclusions-before-crs.conf

Failed same as before with reference to 900120. There are no references to 901200 in anything else besides crs-setup.conf, so unless default is somewhere there -deduplication is unlikely to be the cause.

Replaced

SecAction \
    "id:900120,\
    phase:1,\
    pass,\
    t:none,\
    nolog,\
    tag:'OWASP_CRS',\
    ver:'OWASP_CRS/4.10.0',\
    setvar:tx.early_blocking=1"

with

SecAction "id:900120,phase:1,pass,t:none,nolog,tag:'OWASP_CRS',ver:'OWASP_CRS/4.10.0',setvar:tx.early_blocking=1"

So looked like multi-line was a problem. But I then reverted everything back to my full "expected" config with all the customization, and used 1.6.3 instead of 1.6.4 and... It worked completely fine. So yes it may, indeed, be related to #3350
