Modsecurity OWASP Core Rule Set - base64 false positive rule 941170

OWASP corerulet warning "invalid http request line" triggered by CONNECT method

Modesecurity: Create SecRule exclusion for REQUEST_HEADERS:Transfer-Encoding

QUESTION

Modsecurity OWASP Core Rule Set - base64 false positive rule 941170

Asked 2021-Oct-27 at 12:53

We use ModSecurity 3.X for NGIX with the OWASP core rule set.

We have a problem with image in base64 and the rule 941170.

The pattern of the rule is

The SecRuleUpdateTargetById rule exclusion you provided looks good to me.

To be clear, the effect of that rule exclusion is:

Rule 941170 no longer applies to the screen argument
Rule 941170 still applies to all other arguments as usual
All other rules still apply to all arguments, including screen, as usual

Is there a reason you're not happy with this?

If you're running a super-high security setup which means that the SecRuleUpdateTargetById rule exclusion is too coarse, two suggestions I would make:

If appropriate for your web application, limit the rule exclusion for rule 941170 to only apply to the screen argument and only for a given location (for example, only for requests to /login.php)
Limit the rule exclusion for rule 941170 to only apply to the screen argument and only when screen begins with the string data:image/jpeg;base64

You could even combine both of those suggestions to be extremely specific.

If either, or both, of those sound applicable to your situation, let me know if you would like help to put those rule exclusions together.

Also, what paranoia level are you currently running in, out of interest?

Regarding your suggestion to modify rule 941170's regular expression, it's a bad idea to directly modify third-party rules, such as the Core Rule Set rules. You essentially end up creating your own fork of the rule set, and you're left with the responsibility for maintaining any modifications you make. Upgrading the rule set would become difficult: you would have to remember to keep re-applying, and possibly change, your modifications. In short: rule exclusions are the way to go!

Update

The second rule exclusion described above may look something like this:

QUESTION

OWASP corerulet warning "invalid http request line" triggered by CONNECT method

Asked 2021-Oct-13 at 21:58

Summary:

I have setup a basic WAF with mod-security and the OWASP coreruleset 3.3.2. When using the WAF I see lots of warnings in modsec_audit.log regarding the CONNECT method, which trigger crs rule 920100:

Message: Warning. Match of "rx ^(?i:(?:[a-z]{3,10}\s+(?:\w{3,7}?://[\w\-\./](?::\d+)?)?/[^?#](?:\?[^#\s])?(?:#[\S])?|connect (?:\d{1,3}\.){3}\d{1,3}\.?(?::\d+)?|options \)\s+[\w\./]+|get /[^?#](?:\?[^#\s])?(?:#[\S])?)$" against "REQUEST_LINE" required. [file "/etc/httpd/modsecurity.d/owasp-modsecurity-crs/rules/REQUEST-920-PROTOCOL-ENFORCEMENT.conf"] [line "63"] [id "920100"] [msg "Invalid HTTP Request Line"] [data "CONNECT oneofmy.longer.hostname.here.abcde.com:443 HTTP/1.1"] [severity "WARNING"] [ver "OWASP_CRS/3.3.2"] [tag "application-multi"] [tag "language-multi"] [tag "platform-multi"] [tag "attack-protocol"] [tag "paranoia-level/1"] [tag "OWASP_CRS"] [tag "capec/1000/210/272"]

Details regarding setup: I set up the WAF with mod_security 2.9.2 and httpd. I used the crs-setup.conf.example provided by crs and only modified these two settings regarding threshhold and allowing the CONNECT http method. (CONNECT method is used in our setup for proxy purposes).

QUESTION

Modesecurity: Create SecRule exclusion for REQUEST_HEADERS:Transfer-Encoding

Asked 2021-Jun-07 at 08:00

I want to create an exclusion to disable specific rule (ID:920180) in my system. how should i write the syntax in REQUEST-900-EXCLUSION-RULES-BEFORE-CRS.conf

Here my exclusion but I'm not sure fully covered to disable it:

ANSWER

Answered 2021-Jun-03 at 14:46

Your exclusion rule is almost correct. But the & in front of REQUEST_HEADERS:Transfer-Encoding is missing.

&REQUEST_HEADERS:Transfer-Encoding (with the ampersand) counts the numbers of Transfer-Encoding headers.

Without the & (ampersand), the content of the Transfer-Encoding header is compared to the value 0.

I'm not sure whether you really want to remove the rule in general for nonexistent Transfer-Encoding headers, or whether you want to restrict this to certain clients (IP addresses, user agents, ...). But that is your decision. I don't know exactly what you need.

But in any case, this exclusion rule will now work.

By the way: The current OWASP Core Rule Set repository is https://github.com/coreruleset/coreruleset/.

Vulnerabilities

No vulnerabilities reported

Install coreruleset

You can download it from GitHub.
You can use coreruleset like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.

Support

We strive to make the OWASP ModSecurity CRS accessible to a wide audience of beginner and experienced users. We are interested in hearing any bug reports, false positive alert reports, evasions, usability issues, and suggestions for new detections. Create an issue on GitHub to report a false positive or false negative (evasion). Please include your installed version and the relevant portions of your ModSecurity audit log. We will try and address your issue and potentially ask for additional information in order to reproduce your problem. Please also note that stale issues will be flagged and closed after 120 days. You can search for stale issues with the following search query. Sign up for our Google Group to ask general usage questions and participate in discussions on the CRS.
