When used with Crowdsec it will leverage the local API which will analyze Traefik logs and take decisions on the requests made by users/bots. Malicious actors will be banned based on patterns used against your website.
There are 4 operating modes (CrowdsecMode) for this plugin: Appsec feature is supported from plugin version 1.2.0 and Crowdsec 1.6.0.
The AppSec Component offers:
- Low-effort virtual patching capabilities.
- Support for your legacy ModSecurity rules.
- Combining classic WAF benefits with advanced CrowdSec features for otherwise difficult advanced behavior detection.
More information on appsec in the [Crowdsec Documentation](https://doc.crowdsec.net/docs/next/appsec/intro/).
Remediation offered by [Crowdsec](https://docs.crowdsec.net/u/bouncers/intro) and supported by the plugin can be either `ban` or `captcha`.
For the `ban` remediation the user will be blocked in Traefik (HTTP 403).
For the `captcha` remediation, the user will be redirected to a page to complete a captcha challenge.
On successfull completion, he will be cleaned for a specified period of time before a new resolution challenge is expected if Crowdsec still has a decision to verify the user behavior. See the example captcha for more informations and configuration intructions.
The following captcha providers are supported now:
- [hcaptcha](https://www.hcaptcha.com/)
- [recaptcha](https://www.google.com/recaptcha/about/)
- [turnstile](https://www.cloudflare.com/products/turnstile/)
- [custom/wicketkeeper](https://github.com/a-ve/wicketkeeper)
There are 5 operating modes (CrowdsecMode) for this plugin:
| Mode | Description | | Mode | Description |

The `streaming mode` is recommended for performance, decisions are updated every 60 sec by default and that's the only communication between Traefik and Crowdsec. Every request that happens hits the cache for quick decisions.

Every request that happens hits the cache for quick decisions.
The cache can be local to Traefik using the filesystem, or a separate Redis instance. The cache can be local to Traefik in memory or using a separate Redis instance.
Support for Redis is currently in beta (requires version 7.0.X of Redis).

**/!\ Cache is shared by all services** > [!IMPORTANT]

> **Cache is shared by all services**: This means if an IP is banned, all services which are protected by an instance of the plugin will deny requests from that IP
>
> If you define different caches for different middlewares, only the first one to be instantiated will be bound to the crowdsec stream.
>
> Overall, this middleware is designed in such a way that **only one instance of the plugin is _possible_.** You can have multiple crowdsec middlewares in the same cluster, the key parameters must be aligned (MetricsUpdateIntervalSeconds, CrowdsecMode, CrowdsecAppsecEnabled, etc.)

# Example
## Enabling AppSec WAF feature from crowdsec
You mostly need to configure Crowdsec for this to work by enabling virtual patching and configuring some custom rules.
In the example we use a whoami container protected by crowdsec with virtual patching enabled.
The Traefik instance just needs to know where appsec engine is located
```yaml
labels:
- "traefik.http.middlewares.crowdsec-bar.plugin.bouncer.crowdsecappsecenabled=true"
- "traefik.http.middlewares.crowdsec-bar.plugin.bouncer.crowdsecappsechost=crowdsec:7422"
```
We can try to query normally the whoami server:
```bash
curl http://localhost:8000/foo
```
And then we verify that a malicious request will be blocked:
```bash
curl http://localhost:8000/foo/rpc2
```
You should get a 403 on http://localhost:8000/foo/rpc2
To play the demo environment run:
```bash
make run_appsec
```

## Enabling catpcha response from crowdsec
Crowdsec support 3 remediations solutions `ban`, `captcha`, and `throttle`.
This plugins support the `ban` and `captcha` remediation.
### Traefik configuration
The minimal configuration is defined below.
For now 3 captcha providers are supported:
- [hcaptcha](https://www.hcaptcha.com/)
- [recaptcha](https://www.google.com/recaptcha/about/)
- [turnstile](https://www.cloudflare.com/fr-fr/products/turnstile/)
```yaml
labels:
# Choose captcha provider
- "traefik.http.middlewares.crowdsec.plugin.bouncer.captchaProvider=hcaptcha"
# Define captcha site key
- "traefik.http.middlewares.crowdsec.plugin.bouncer.captchaSiteKey=FIXME"
# Define captcha secret key
- "traefik.http.middlewares.crowdsec.plugin.bouncer.captchaSecretKey=FIXME"
# Define captcha grace period seconds
- "traefik.http.middlewares.crowdsec.plugin.bouncer.captchaGracePeriodSeconds=1800"
# Define captcha HTML file path
- "traefik.http.middlewares.crowdsec.plugin.bouncer.captchaHTMLFilePath=/captcha.html"
```
The captcha HTML file must be present in the Traefik container (bind mounted or added during a custom build).
It is not directly accessible from Traefik even when importing the plugin, so [download](https://raw.githubusercontent.com/maxlerebourg/crowdsec-bouncer-traefik-plugin/master/captcha.html) it locally to expose it to Traefik.
```yaml
...
traefik:
image: "traefik:v3.0.0"
volumes:
- './captcha.html:/captcha.html'
...
```
### Crowdsec configuration
Crowdsec by default will take the ban action on suspicious activity detected in logs.
To instruct Crowdsec to use captcha remediation, change the `/etc/crowdsec/profiles.yaml`.
2 modes are supported:
- Always return a captcha decision
- Return a captcha decision the first X times and then a ban decision.
The second mode could be used to prevent repeated malicious activity.
More information is available on configuring Crowdsec in the [official documentation](https://docs.crowdsec.net/docs/next/local_api/profiles/captcha_profile/).
```yaml
...
crowdsec:
image: crowdsecurity/crowdsec:v1.6.1-2
volumes:
# For captcha and ban mixed decision
- './profiles.yaml:/etc/crowdsec/profiles.yaml:ro'
# For captcha only remediation
# - './profiles_captcha_only.yaml:/etc/crowdsec/profiles.yaml:ro'
...
```
## Exemple navigation
We can try to query normally the whoami server:
```bash
curl http://localhost:8000/foo
```
We can try to ban ourself
```bash
docker exec crowdsec cscli decisions add --ip 10.0.0.20 -d 4h --type captcha
```
![image decision captcha](image_decision_captcha.png)
We will see in the browser the captcha validation page:
![image captcha validation](image_captcha_validation.png)
To play the demo environment run:
```bash
make run_captcha
```
> Note, if we are banned with a "ban" decision from crowdsec a captcha will not be asked and you will have to wait for the decision to expire or remove it manually.
```bash
docker exec crowdsec cscli decisions add --ip 10.0.0.10 -d 10m --type ban
```
## Captcha Workflow
> Context: The user has no decision attached to his IP

# Example
## Adding a custom ban page
Traefik can return a custom HTML ban page along with the 403 HTTP response code.
This can be usefull as some browser (Firefox for instance) return a 403 blank webpage and we can mistake a server/reverse-proxy error with a ban from Crowdsec.
### Traefik configuration
```yaml
labels:
# Define ban HTML file path
- "traefik.http.middlewares.crowdsec.plugin.bouncer.banHtmlFilePath=/ban.html"
```
The ban HTML file must be present in the Traefik container (bind mounted or added during a custom build).
It is not directly accessible from Traefik even when importing the plugin, so [download](https://raw.githubusercontent.com/maxlerebourg/crowdsec-bouncer-traefik-plugin/master/ban.html) it locally to expose it to Traefik.
```yaml
...
traefik:
image: "traefik:v2.11.0"
volumes:
- './ban.html:/ban.html'
...
```
## Exemple navigation
We can try to query normally the whoami server:
```bash
curl http://localhost:8000/foo
```
We can try to ban ourself
```bash
docker exec crowdsec cscli decisions add --ip 10.0.0.20 -d 4h --type ban
```
![image decision ban](image_decision_ban.png)
We will see in the browser the ban custom page:
To play the demo environment run:
```bash
make run_custom_ban_page
```
## Another thing to note
In the html of the ban page, you can use:
- {{ .ClientIP }} to display the IP used to ban the request.
- {{ .RemediationReason }} that convert on runtime into why the ban page is served. It's an enum with "APPSEC", "LAPI", "TECHNICAL_ISSUE" and it is useful to help user understand why the request is blocked.
- {{ .CustomHeader }} value of the specified Request Header (for example X-Request-ID)
```
<script>var remediation = "{{ .RemediationReason }}"</script>
<script>var clientIp = "{{ .ClientIP }}"</script>
<script>var traceID = "{{ .TraceID }}"</script>
```
With the above tweak and some other js, you can customize your ban page on runtime.

# Example
Read the example captcha before this, to better understand what is done here.
### Traefik configuration
The minimal configuration is defined below to implement custom captcha.
This documentation use https://github.com/a-ve/wicketkeeper, a self-hosted captcha provider that have a similar API than big providers.
Minimal API requirement:
- the JS file URL to load the captcha on the served `captcha.html`
- the HTML className to tell to the JS where to display the challenge
- the verify URL endpoint to send the field `response` from the captcha with `content-type: application/x-www-form-urlencoded`
- the name of the field when you POST the resolved captcha to Traefik
- the JS file need to respect the `data-callback` on the div that contains the captcha if you use our template, but you can customize it by your side
```yaml
traefik:
...
labels:
# Choose captcha provider
- "traefik.http.middlewares.crowdsec.plugin.bouncer.captchaProvider=custom"
# Define captcha grace period seconds
- "traefik.http.middlewares.crowdsec.plugin.bouncer.captchaGracePeriodSeconds=1800"
- "traefik.http.middlewares.crowdsec.plugin.bouncer.captchaCustomJsURL=http://captcha.localhost:8000/fast.js"
# Inside Traefik container the plugin must be able to reach wicketkeeper service so we can go through a Traefik localhost
# domain which would resolve traefik itself and the port for the dashboard
- "traefik.http.middlewares.crowdsec.plugin.bouncer.CaptchaCustomValidateURL=http://wicketkeeper:8080/v0/siteverify"
- "traefik.http.middlewares.crowdsec.plugin.bouncer.CaptchaCustomKey=wicketkeeper"
- "traefik.http.middlewares.crowdsec.plugin.bouncer.CaptchaCustomResponse=wicketkeeper_solution"
# Define captcha HTML file path
- "traefik.http.middlewares.crowdsec.plugin.bouncer.captchaHTMLFilePath=/captcha.html"
```
```yaml
wicketkeeper:
image: ghcr.io/a-ve/wicketkeeper:latest
user: root
ports:
- "8080:8080"
environment:
- LISTEN_PORT=8080
- REDIS_ADDR=redis:6379
- DIFFICULTY=4
- ALLOWED_ORIGINS=*
- PRIVATE_KEY_PATH=/data/wicketkeeper.key
volumes:
- ./data:/data
depends_on:
- redis
redis:
image: redis/redis-stack-server:latest
```
```html
<div id="captcha" class="{{ .FrontendKey }}" data-sitekey="{{ .SiteKey }}" data-callback="captchaCallback" data-challenge-url="http://captcha.localhost:8000/v0/challenge">
```
## Exemple navigation
We can try to query normally the whoami server:
```bash
curl http://localhost:8000/foo
```
We can try to ban ourself and retry.
```bash
docker exec crowdsec cscli decisions add --ip 10.0.0.20 -d 10m --type captcha
```
To play the demo environment run:
```bash
make run_custom_captcha
```

## Separate LAPI and Appsec HTTP/S config
To separate TLS config for LAPI and Appsec, you can use all the TLS LAPI variable beginning with `CrowdsecLapi...` into `CrowdsecAppsec...`.
Don't forget to set `CrowdsecAppsecScheme: HTTP` or `HTTPS` to trigger the separate setup.
