Go-FTW - Framework for Testing WAFs in Go!

pre-commit Go Report Card Go Doc PkgGoDev Release Coverage Quality Gate Status OpenSSF Scorecard

Go-FTW is a replacement for FTW which had reached its limits in terms of maintainability and performance.

Features of Go-FTW include:

  • fully customizable HTTP traffic
  • CI/CD friendly
  • fast
  • syntax checking of test files

Install

Go to the releases page and get a binary release that matches your OS (scroll down to Assets).

If you have Go installed and configured to run Go binaries from your shell you can also run

go install github.com/coreruleset/go-ftw@latest

Example Usage

The go-ftw is designed to run Web Application Firewall (WAF) unit tests. The primary focus is the OWASP ModSecurity Core Rule Set.

In order to run the tests, you need to prepare the following:

  1. Active WAF
  2. Log where the WAF writes the alert messages
  3. go-ftw config file .ftw.yaml in the local folder or in your home folder (see YAML Config file for more information).
  4. At least one unit test in (go)-ftw's yaml format.

YAML Config file

With the configuration, you can set paths for your environment, enable and disable features and you can also use it to alter the test results.

The config file has six basic settings:

  • logfile : path to WAF log with alert messages, relative or absolute
  • testoverride : a list of things to override (see Overriding tests below)
  • mode : "default" or "cloud" (only change it if you need "cloud")
  • logmarkerheadername : name of an HTTP header used for marking log messages, usually X-CRS-TEST (see How log parsing works below)
  • maxmarkerretries : the maximum number of times the search for log markers will be repeated; each time an additional request is sent to the web server, eventually forcing the log to be flushed
  • maxmarkerloglines the maximum number of lines to search for a marker before aborting

You can probably leave the last three alone, they are set to sane defaults.

Example with absolute logfile:

logfile: /apache/logs/error.log
logmarkerheadername: X-CRS-TEST
testoverride:
mode: "default"

Example with relative logfile:

logfile: ../logs/error.log
logmarkerheadername: X-CRS-TEST
testoverride:
mode: "default"

Example with minimal definitions:

The minimal requirement for go-ftw is to have a logfile when running in default mode:

logfile: ../logs/error.log

By default, go-ftw looks for a file in $PWD / local folder with the name .ftw.yaml. If this can not be found, it will look in the user's HOME folder. You can pass the --config <config file name> to point it to a different file.

WAF Server

I normally perform my testing using the Core Rule Set.

You can start the containers from that repo using docker compose:

git clone https://github.com/coreruleset/coreruleset.git
cd coreruleset
docker compose -f tests/docker-compose.yml up -d modsec2-apache

Logfile

Running in default mode implies you have access to a logfile for checking the WAF behavior against test results. For this example, assuming you are in the base directory of the coreruleset repository, these are the configurations for apache and nginx:

---
logfile: 'tests/logs/modsec2-apache/error.log'
---
logfile: 'tests/logs/modsec3-nginx/error.log'

Running

This is the help for the run command:

./ftw run --help
Run all tests below a certain subdirectory. The command will search all y[a]ml files recursively and pass it to the test engine.

      --read-timeout duration                  timeout for receiving responses during test execution (default 10s)
      --show-failures-only                     shows only the results of failed tests
  -t, --time                                   show time spent per test
      --wait-delay duration                    Time to wait between retries for all wait operations. (default 1s)
      --wait-for-connection-timeout duration   Http connection timeout, The timeout includes connection time, any redirects, and reading the response body. (default 3s)
      --wait-for-expect-body-json string       Expect response body JSON pattern.
      --wait-for-expect-body-regex string      Expect response body pattern.
      --wait-for-expect-body-xpath string      Expect response body XPath pattern.
      --wait-for-expect-header string          Expect response header pattern.
      --wait-for-expect-status-code int        Expect response code e.g. 200, 204, ... .
      --wait-for-host string                   Wait for host to be available before running tests.
      --wait-for-insecure-skip-tls-verify      Skips tls certificate checks for the HTTPS request.
      --wait-for-no-redirect                   Do not follow HTTP 3xx redirects.
      --wait-for-timeout duration              Sets the timeout for all wait operations, 0 is unlimited. (default 10s)

Global Flags:
      --cloud              cloud mode: rely only on HTTP status codes for determining test success or failure (will not process any logs)
      --config string      specify config file (default is $PWD/.ftw.yaml)
      --debug              debug output
      --overrides string   specify file with platform specific overrides
      --trace              trace output: really, really verbose

All the wait for flags are implemented using the wait4x library. See their examples on how to use them. In our flags we added the prefix --wait-for but they behave similarly.

Note: Duration flags above accept any input valid for time.ParseDuration.

Here's an example on how to run your tests recursively in the folder tests:

ftw run -d tests -t

And the result should be similar to:

❯ ./ftw run -d tests -t

Output

Now you can choose how the output of the test session is shown by passing the -o flag. The default output is -o normal, and it will show the emojis in all the supported terminals. If yours doesn't support emojis, or you want a plain format, you can use -o plain:

./ftw run -d tests -o plain -i 932240

To support automation for processing the test results, there is also a new JSON output available using -o json:

{
  "run": 8,
  "success": [
    "911100-1",
    "911100-2",
    "911100-3",
    "911100-4",
    "911100-5",
    "911100-6",
    "911100-7",
    "911100-8"
  ],
  "failed": null,
  "skipped": [
    "913100-1",
    "913100-2",
    "913100-3",
    "...",
    "980170-2"
  ],
  "ignored": null,
  "forced-pass": null,
  "forced-fail": null,
  "runtime": {
    "911100-1": 20631077,
    "911100-2": 14112617,
    "911100-3": 14524897,
    "911100-4": 14699391,

    "911100-8": 20658905
  },
  "TotalTime": 134095281
}

Then it is easy to use your jq skils to get the information you want.

The list of supported outputs is:

  • "normal"
  • "quiet"
  • "github"
  • "json"
  • "plain"

Only show failures

If you are only interested to see when tests fail, there is a new flag --show-failures-only that does exactly that. This is helpful when running in CI/CD systems like GHA to get shorter outputs.

Additional features

  • templates with the power of Go text/template. Add your template to any data: sections and enjoy!
  • Sprig functions can be added to templates as well.
  • Override test results.
  • Cloud mode! This new mode will ignore log files and rely solely on the HTTP status codes of the requests for determining success and failure of tests.

With templates and functions, you can simplify bulk test writing, or even read values from the environment while executing. These features allow you to write tests like this:

data: 'foo=%3d{{ "+" | repeat 34 }}'

Will be expanded to:

data: 'foo=%3d++++++++++++++++++++++++++++++++++'

But also, you can get values from the environment dynamically when the test is run:

data: 'username={{ env "USERNAME" }}

Will give you, as you expect, the username running the tests:

data: 'username=fzipi

Other interesting functions you can use are: randBytes, htpasswd, encryptAES, etc.

Overriding tests

Sometimes you have tests that work well for some platform combinations, e.g. Apache + ModSecurity 2, but fail for others, e.g. NGiNX + ModSecurity 3. Taking that into account, you can override test results using the testoverride config param. The test will be skipped, and the result forced as configured.

Tests can be altered using four lists:

  • input allows you to override global parameters in tests. The following ones can be overridden:
    • dest_addr: overrides the destination address (accepts IP or hostname)
    • override_empty_host_header: if true and dest_addr override is also set, empty Host headers will be replaced with dest_addr
    • port: overrides the port number
    • protocol: overrides the protocol
    • uri: overrides the uri
    • version: overrides the HTTP version. E.g. "HTTP/1.1"
    • headers: overrides headers, the format is a map of strings
    • method: overrides the method used to perform the request
    • data: overrides data sent in the request
    • autocomplete_headers: overrides header autocompletion (currently sets Connection: close and Content-Length for requests with body data)
    • encodedrequest: overrides base64 encoded request
  • ignore is for tests you want to ignore. You should add a comment on why you ignore the test
  • forcepass is for tests you want to pass unconditionally. You should add a comment on why you force to pass the test
  • forcefail is for tests you want to fail unconditionally. You should add a comment on why you force to fail the test

Each list is populated by regular expressions (see https://pkg.go.dev/regexp), which match against test IDs. The following is an example using all the lists mentioned above:

...
testoverride:
  input:
    dest_addr: "192.168.1.100"
    port: 8080
    protocol: "http"
  ignore:
    # text comes from our friends at https://github.com/digitalwave/ftwrunner
    '941190-3$': 'known MSC bug - PR #2023 (Cookie without value)'
    '941330-1$': 'know MSC bug - #2148 (double escape)'
    '942480-2$': 'known MSC bug - PR #2023 (Cookie without value)'
    '944100-11$': 'known MSC bug - PR #2045, ISSUE #2146'
    '^920': 'All the tests about Protocol Attack (rules starting with "920") will be ignored'
  forcefail:
    '123456-01$': 'I want this specific test to fail, even if passing'
  forcepass:
    '123456-02$': 'This test will always pass'
    '123457-.*': 'All the tests about rule 123457 will always pass'

You can combine any of ignore, forcefail and forcepass to make it work for you.

☁️ Cloud mode

Most of the tests rely on having access to a logfile to check for success or failure. Sometimes that is not possible, for example, when testing cloud services or servers where you don't have access to logfiles and/or logfiles won't have the information you need to decide if the test was good or bad.

With cloud mode, we move the decision on test failure or success to the HTTP status code received after performing the test. The general idea is that you set up your WAF in blocking mode, so anything matching will return a block status (e.g. 403), and if not we expect a 2XX return code.

You will also want to override the IP configured in the tests, and use the one from your cloud provider instead.

An example config file for this is:

---
mode: 'cloud'
testoverride:
  input:
    dest_addr: "<your cloud WAF IP>"
    port: 80

Save this file as cloud-test.yaml and edit the WAF IP.

Then run: ./ftw run --config cloud-test.yaml

How log parsing works

The WAF's log file with the alert messages is parsed and compared to the expected output defined in the unit test under log_contains or no_log_contains. Note that the expected output may contain multiple checks (E.g. log_contains and status). If any of the checks fail, the test will fail.

The problem with log files is that go-ftw is very, very fast and the log files are not updated in real time. Frequently, the web server / WAF is not syncing the file fast enough. That results in a situation where go-ftw won't find the log messages it has triggered.

To make log parsing consistent and guarantee that we will see output when we need it, go-ftw will send a request that is meant to write a marker into the log file before the individual test and another marker after the individual test.

If go-ftw does not see the finishing marker after executing the request, it will send the marker request again until the webserver is forced to write the log file to the disk and the marker can be found.

The container images for Core Rule Set can be configured to write these marker log lines by setting the CRS_ENABLE_TEST_MARKER environment variable. If you are testing a different test setup, you will need to instrument it with a rule that generated the marker in the log file via a rule alert (unless you are using "cloud mode").

The rule for CRS looks like this:

# Write the value from the X-CRS-Test header as a marker to the log
SecRule REQUEST_HEADERS:X-CRS-Test "@rx ^.*$" \
  "id:999999,\
  pass,\
  phase:1,\
  log,\
  msg:'X-CRS-Test %{MATCHED_VAR}',\
  ctl:ruleRemoveById=1-999999"

The rule looks for an HTTP header named X-CRS-Test and writes its value to the log, the value being the UUID of a test stage. If the header does not exist, the rule will be skipped and no marker will be written. If the header is found, the rule will also disable all further matching against the request to ensure that reported matches only concern actual test requests.

You can configure the name of the HTTP header by setting the logmarkerheadername option in the configuration to a custom value (the value is case-insensitive).

Wait for backend service to be ready

Sometimes you need to wait for a backend service to be ready before running the tests. For example, you may need to wait for an additional container to be ready before running the tests. Now you can do that by passing the --wait-for-host flag. The value of this option is a URL that will be requested, and you can configure the expected result using the following additional flags:

  • --wait-for-host: Wait for host to be available before running tests.
  • --wait-for-connection-timeout Http connection timeout, The timeout includes connection time, any redirects, and reading the response body. (default 3s)
  • --wait-for-expect-body-json Expect response body JSON pattern.
  • --wait-for-expect-body-regex Expect response body pattern.
  • --wait-for-expect-body-xpath Expect response body XPath pattern.
  • --wait-for-expect-header Expect response header pattern.
  • --wait-for-expect-status-code Expect response code e.g. 200, 204, ... .
  • --wait-for-insecure-skip-tls-verify Skips tls certificate checks for the HTTPS request.
  • --wait-for-no-redirect Do not follow HTTP 3xx redirects.
  • --wait-for-timeout Sets the timeout for all wait operations, 0 is unlimited. (default 10s)

(EXPERIMENTAL) Quantitative testing

In the latest version of go-ftw, we have added a new feature that allows you to run quantitative tests. This feature is still experimental and may change in the future.

What is the idea behind quantitative tests?

Quantitative testing mode provides a means to to quantify the amount of false positives to be expected in production for a given rule. We use well-known corpora of texts to generate plausible, non-malicious payloads. Whenever such a payload is blocked by the WAF, the detection is considered to be a false positive.

Anyone can create their own corpora of texts and use them to test their WAF. Each corpus essentially consists of a list of strings, which may be sent to the WAF, depending on the configuration of the run.

The result of a test run is a percentage of false positives. The lower the percentage, the better the WAF is at not blocking benign payloads for a given rule. However, since we use generic corpora in our tests, the strings in those corpora will not necessarily be representative of the domain of a specific site. This means that a rule with a low false positive rate can still produce many false positives in specific contexts, e.g., when a website contains programming language code.

What is a corpus? Why do I need one?

A corpus is a collection of texts that is used to generate payloads. The texts can contain anything, from news articles to books. The idea is to have a large collection of texts that can be used to generate payloads. Well-known corpora usually have a domain or context, e.g., news headlines, or English books of the 18th century.

The default corpus is the Leipzig Corpora Collection, which is a collection of texts from the web.

How to create a corpus?

You can create your own corpus by collecting texts from the web, or from books, articles, etc. You could even use the contents of your own website as a corpus! What you will need to do is to implement the following interfaces:

  • corpus.Corpus
  • corpus.File
  • corpus.Iterator
  • corpus.Payload

You can see an example of how to implement the corpus.Corpus interface in the corpus/leipzig package.

How to run quantitative tests?

To run quantitative tests, you just need to pass the quantitative flag to ftw.

The corpus will be downloaded and cached locally for future use. You can also specify the size of the corpus, the language, the source, and the year of the corpus. The bare minimum parameter that you must specify is the directory where the CRS rules are stored.

Here is the help for the quantitative command:

❯ ./go-ftw quantitative -h

Example of running quantitative tests

This will run with the default leipzig corpus and size of 10K payloads.

❯ ./go-ftw quantitative -d ../coreruleset -s 10K
Running quantitative tests
Run 10000 payloads in 18.482979709s
Total False positive ratio: 408/10000 = 0.0408
False positives per rule:
  Rule 920220: 198 false positives
  Rule 920221: 198 false positives
  Rule 932235: 4 false positives
  Rule 932270: 2 false positives
  Rule 932380: 2 false positives
  Rule 933160: 1 false positives
  Rule 942100: 1 false positives
  Rule 942230: 1 false positives
  Rule 942360: 1 false positives

This will run with the default leipzig corpus and size of 10K payloads, but only for the rule 920350.

❯ ./go-ftw quantitative -d ../coreruleset -s 10K -r 932270
Running quantitative tests
Run 10000 payloads in 15.218343083s
Total False positive ratio: 2/10000 = 0.0002
False positives per rule:
  Rule 932270: 2 false positives

If you add --debug to the command, you will see the payloads that cause false positives.

Future work for quantitative tests

This feature will enable us to compare between two different versions of CRS (or any two rules) and see, for example, if any modification to the rule has caused more false positives.

Integrating it to the CI/CD pipeline will allow us to check every PR for false positives before merging.

Library usage

go-ftw can be used as a library also. Just include it in your project:

go get github.com/coreruleset/go-ftw

Then, for the example below, import at least these:

package main

import (
    "net/url"
    "os"
    "path/filepath"
    "strconv"

    "github.com/bmatcuk/doublestar/v4"
    "github.com/coreruleset/go-ftw/config"
    "github.com/coreruleset/go-ftw/output"
    "github.com/coreruleset/go-ftw/runner"
    "github.com/coreruleset/go-ftw/test"
    "github.com/rs/zerolog"
)

And a sample code:

     // sample from https://github.com/corazawaf/coraza/blob/v3/dev/testing/coreruleset/coreruleset_test.go#L215-L251
    var tests []test.FTWTest
    err = doublestar.GlobWalk(crsReader, "tests/regression/tests/**/*.yaml", func(path string, d os.DirEntry) error {
        yaml, err := fs.ReadFile(crsReader, path)
        if err != nil {
            return err
        }
        t, err := test.GetTestFromYaml(yaml)
        if err != nil {
            return err
        }
        tests = append(tests, t)
        return nil
    })
    if err != nil {
        log.Fatal(err)
    }

    u, _ := url.Parse(s.URL)
    host := u.Hostname()
    port, _ := strconv.Atoi(u.Port())
    zerolog.SetGlobalLevel(zerolog.InfoLevel)
    cfg, err := config.NewConfigFromFile(".ftw.yml")
    if err != nil {
        log.Fatal(err)
    }
    cfg.WithLogfile(errorPath)
    cfg.TestOverride.Input.DestAddr = &host
    cfg.TestOverride.Input.Port = &port

    res, err := runner.Run(cfg, tests, runner.RunnerConfig{
                    ShowTime: false,
                    }, output.NewOutput("quiet", os.Stdout))
    if err != nil {
        log.Fatal(err)
    }


    if len(res.Stats.Failed) > 0 {
		log.Errorf("failed tests: %v", res.Stats.Failed)
	}
