 # Crowdsec Bouncer Traefik plugin
 
-This plugin aims to implement a Crowdsec Bouncer in a traefik plugin.

 > [CrowdSec](https://www.crowdsec.net/) is an open-source and collaborative IPS (Intrusion Prevention System) and a security suite.
 > We leverage local behavior analysis and crowd power to build the largest CTI network in the world.

+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 3 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                                                                                                                                                                                                                                                                                           |
-|------|------|
+| ------ | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
 | none   | If the client IP is on ban list, it will get a http code 403 response. Otherwise, request will continue as usual. All request call the Crowdsec LAPI                                                                                                                                                  |
 | live   | If the client IP is on ban list, it will get a http code 403 response. Otherwise, request will continue as usual. The bouncer can leverage use of a local cache in order to reduce the number of requests made to the Crowdsec LAPI. It will keep in cache the status for each IP that makes queries. |
 | stream | Stream Streaming mode allows you to keep in the local cache only the Banned IPs, every requests that does not hit the cache is authorized. Every minute, the cache is updated with news from the Crowdsec LAPI.                                                                                       |
+| alone  | Standalone mode, similar to the streaming mode but the blacklisted IPs are fetched on the CAPI. Every 2 hours, the cache is updated with news from the Crowdsec CAPI. It does not include any locally banned IP, but can work without a crowdsec service.                                             |
+| appsec | Disable Crowdsec IP checking but apply Crowdsec Appsec checking. This mode is intended to be used when Crowdsec IP checking is applied at the Firewall Level.                                                                                                                                         |
 
-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.

 ## Usage
 
 To get started, use the `docker-compose.yml` file.
 
 You can run it with:
+
 ```bash
 make run
 ```
 
 ### Note
 
-**/!\ Since Release 1.1.0, the cache is no longer duplicated but shared by all services**
-*This lowers the overhead of the cache in memory and the numbers of cache to fetch it from crowdsec in situations with many services*
+> [!IMPORTANT]  
+> Some of the behaviours and configuration parameters are shared globally across *all* crowdsec middlewares even if you declare different middlewares with different settings. 
+>
+> **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.)
 
+> [!WARNING]  
+> **Appsec maximum body limit is defaulted to 10MB**
+> *Be careful when you upgrade to >1.4.x*

 ### About
 
-Me and [mathieuHa](https://github.com/mathieuHa) have been using traefik since 2020 at [Primadviz](https://primadviz.com).
+[mathieuHa](https://github.com/mathieuHa) and [I](https://github.com/maxlerebourg) have been using Traefik since 2020 at [Primadviz](https://primadviz.com).
 We come from a web development and security engineer background and wanted to add the power of a very promising technology (Crowdsec) to the edge router we love.
 
-We initially ran into this project: https://github.com/fbonalair/traefik-crowdsec-bouncer
+We initially ran into this project: [github.com/fbonalair/traefik-crowdsec-bouncer](https://github.com/fbonalair/traefik-crowdsec-bouncer)
 It was using traefik and forward auth middleware to verify every request.  
 They had to go through a webserver which then contacts another webservice (the crowdsec LAPI) to make a decision based on the source IP.  
 We initially proposed some improvements by implementing a streaming mode and a local cache.  
-With the Traefik hackathon we decided to implement our solution directly as a traefik plugin which could be found by everyone on plugins.traefik.io and be more performant.

+# 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
+```

+# Example
+## 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
+```

+# 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"
+```

+redis:

+```
+
+```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
+```
