 # Crowdsec Bouncer Traefik plugin
 
-This plugins aims to implement a Crowdsec Bouncer into a traefik plugin.
+> New! This plugin now supports [AppSec](https://doc.crowdsec.net/docs/next/appsec/intro/) feature including virtual patching and capabilities support for your legacy ModSecurity rules.

+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/)
+
+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 recommanded mode for performance is the streaming mode, decisions are updated every 60 sec by default and that's the only communication between traefik and crowdsec. Every requests that happens hits the cache for quick decisions.
+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.
+
+The cache can be local to Traefik in memory or using a separate Redis instance.

 ## Usage
 
 To get started, use the `docker-compose.yml` file.
 
 You can run it with:
+
 ```bash
 make run
 ```
 
 ### Note
-Each middleware in traefik has it's own data and is instanciated by service.
-This means if there are 10 services protected by the bouncer in streaming alone or live mode, the cache will be duplicated to all 10 services.
-This is because traefik does not allow plugins to store data locally that can be consummed.
 
-The synchronisation with the crowdsec service will happen also 10 times in the period selected.
+**/!\ Cache is shared by all services**
-It should be taken into account when fixing this period so each middleware has time to sync data from crowdsec.
+_This means if an IP is banned, all services which are protected by an instance of the plugin will deny requests from that IP_
+Only one instance of the plugin is _possible_.
 
-At each start of synchronisation, the middleware will wait a random number of seconds to avoid simultaneous calls to crowdsec.
+**/!\ Appsec maximum body limit is defaulted to 10MB**
+_By careful when you upgrade to >1.4.x_

+
 You can then run all the containers:
+
 ```bash
-docker-compose up -d
+docker compose up -d
 ```
 
-#### Add manually an IP to the blocklist (testing purpose)
+#### Use certificates to authenticate with CrowdSec
+
+You can follow the example in `examples/tls-auth` to view how to authenticate with client certificates with the LAPI.  
+In that case, communications with the LAPI must go through HTTPS.
+
+A script is available to generate certificates in `examples/tls-auth/gencerts.sh` and must be in the same directory as the inputs for the PKI creation.
+
+#### Use HTTPS to communicate with the LAPI
+
+To communicate with the LAPI in HTTPS you need to either accept any certificates by setting the `crowdsecLapiTLSInsecureVerify` to true or add the CA used by the server certificate of Crowdsec using `crowdsecLapiTLSCertificateAuthority` or `crowdsecLapiTLSCertificateAuthorityFile`.
+Set the `crowdsecLapiScheme` to https.
+
+Crowdsec must be listening in HTTPS for this to work.
+Please see the [tls-auth example](https://github.com/maxlerebourg/crowdsec-bouncer-traefik-plugin/blob/main/examples/tls-auth/README.md) or the official documentation: [docs.crowdsec.net/docs/local_api/tls_auth/](https://docs.crowdsec.net/docs/local_api/tls_auth/)
+
+#### Manually add an IP to the blocklist (for testing purposes)
 
 ```bash
-docker-compose up -d crowdsec
+docker compose up -d crowdsec
-docker exec crowdsec cscli decisions add --ip 10.0.0.10 # this will be effective 4h
+docker exec crowdsec cscli decisions add --ip 10.0.0.10 -d 10m # this will be effective 10min
 docker exec crowdsec cscli decisions remove --ip 10.0.0.10
+docker exec crowdsec cscli decisions add --ip 10.0.0.10 -d 10m -t captcha # this will return a captcha challenge

 ### Local Mode
 
 Traefik also offers a developer mode that can be used for temporary testing of plugins not hosted on GitHub.
 To use a plugin in local mode, the Traefik static configuration must define the module name (as is usual for Go packages) and a path to a [Go workspace](https://golang.org/doc/gopath_code.html#Workspaces), which can be the local GOPATH or any directory.

-In the exemple we use another instance of traefik with the container named cloudflare to simulate a front proxy
-
-The "internal" Traefik instance is configured to trust the cloudflare forward headers
-```yaml
-  - "--entrypoints.web.forwardedheaders.trustedips=172.21.0.5"
-```
-
-We configure the middleware to trust as well the IP:
-```yaml
-    - "traefik.http.middlewares.crowdsec1.plugin.bouncer.forwardedheaderstrustedips=172.21.0.5"
-```
-
-To run the environnement run:
-```bash
-make run_behind_proxy
-```
-

+# 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
+## Behind another proxy service (ex: clouflare)
+
+You need to configure your Traefik to trust Forwarded headers by your front proxy
+In the example we use another instance of traefik with the container named cloudflare to simulate a front proxy
+
+The "internal" Traefik instance is configured to trust the cloudflare forward headers
+This helps Traefik choose the right IP of the client: see https://doc.traefik.io/traefik/routing/entrypoints/#forwarded-headers
+```yaml
+  - "--entrypoints.web.forwardedheaders.trustedips=172.21.0.5"
+```
+
+We configure the middleware to trust as well the IP:
+```yaml
+    - "traefik.http.middlewares.crowdsec1.plugin.bouncer.forwardedheaderstrustedips=172.21.0.5"
+```
+
+To play the demo environment run:

+### Install vagrant
+
+##### On linux
+
+```bash
+curl -fsSL https://apt.releases.hashicorp.com/gpg | sudo tee /usr/share/keyrings/hashicorp-archive-keyring.asc
+echo "deb [ signed-by=/usr/share/keyrings/hashicorp-archive-keyring.asc ] https://apt.releases.hashicorp.com $(lsb_release -cs) main" | sudo tee /etc/apt/sources.list.d/hashicorp.list
+sudo apt-get update && sudo apt-get install vagrant
+```
+
+### Install libvirt
+
+```bash
+sudo apt install -y qemu-kvm virt-manager libvirt-daemon-system virtinst libvirt-clients bridge-utils
+sudo systemctl enable --now libvirtd
+sudo systemctl start libvirtd
+sudo usermod -aG kvm $USER
+sudo usermod -aG libvirt $USER
+```
+
+### Install the plugin vagrant-libvirt
+
+```bash
+vagrant plugin install vagrant-libvirt
+```
+
+#### Start the VM
+
+```bash
+sudo vagrant up --provider=libvirt
+```
+
+#### Destroy the VM
+
+```bash
+sudo vagrant destroy -f
+```
+
+#### SSH in the VM
+
+```bash
+sudo vagrant ssh
+```
+
+### Context
+
+Traefik is installed as a systemd service.
+It is configured with the dashboard activated and listening on port 8081 and port 80 for the web
+
+Crowdsec is started and listening on port 8080.
+Certificates are generated on the provision step of vagrant.
+
+Whoami is installed as a systemd service.
+It is configured to listen on port 9000.
+
+Whoami is accessible from traefik on port 80 at any domain and path
+
+For example: curl http://localhost:80/test
+
+The Plugin / Bouncer use certificates to validate the server certificates and authenticates with the Crowdsec local api.

+# 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 grade 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/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
+```

+# Example
+## Using https communication and tls authentication with Crowdsec
+
+##### Summary
+This example demonstrates the use of https between the Traefik plugin and the Crowdsec LAPI.
+
+It is possible to communicate with the LAPI in https and still authenticate with API key.
+You can add the client TLS certificate generated to authenticate without any Token in the plugin.
+
+However, note that it is not possible to authenticate with TLS client certificate without https setup for the LAPI.
+
+##### Details
+
+Simple HTTPS communication: It is possible to talk to Crowdsec LAPI which is configured with a self-signed certificate
+In that case the setting **crowdsecLapiTLSInsecureVerify** must be set to true.
+
+It is recommended to validate the certificate presented by Crowdsec LAPI using the Certificate Authority which created it.
+
+You can provide the Certificate Authority using:
+* A file path readable by Traefik
+```yaml
+http:
+  middlewares:
+    crowdsec:
+      plugin:
+        bouncer:
+          crowdsecLapiTlsCertificateAuthorityFile: /etc/traefik/certs/crowdsecCA.pem
+```
+* The PEM encoded certificate as a text variable
+
+In the static file configuration of Traefik
+```yaml
+http:
+  middlewares:
+    crowdsec:
+      plugin:
+        bouncer:
+          crowdsecLapiTlsCertificateAuthority: |-
+              -----BEGIN CERTIFICATE-----

+              Q0veeNzBQXg1f/JxfeA39IDIX1kiCf71tGlT
+              -----END CERTIFICATE-----
+```
+In a dynamic configuration of a provider (ex docker) as a Label
+```yaml
+services:
+  whoami-foo:
+    image: traefik/whoami
+    labels:
+      - |
+        traefik.http.middlewares.crowdsec-foo.plugin.bouncer.crowdsecLapiTlsCertificateAuthority=
+        -----BEGIN CERTIFICATE-----
+        MIIEBzCCAu+gAwIBAgICEAAwDQYJKoZIhvcNAQELBQAwgZQxCzAJBgNVBAYTAlVT
+        MRAwDgYDVQQHDAdTZWF0dGxlMRMwEQYDVQQIDApXYXNoaW5ndG9uMSIwIAYDVQQK

+        Q0veeNzBQXg1f/JxfeA39IDIX1kiCf71tGlT
+        -----END CERTIFICATE-----
+```
+
+The example tls-auth presents 2 services, foo and bar which comes with the bouncer.
+At startup, certificates are created in a shared docker volume by a sidecar container which exits after.
+
+Traefik will use client and CA certificates.
+The Bouncer will use server and CA certificates.
+
+The service `whoami-foo` will authenticate with an **API key** over HTTPS after verifying the server certificate with CA.
+The service `whoami-bar` will authenticate with a **client certificate** signed by the CA.
+
+Access to a route that communicate via https and authenticate with API-key:
+```
+curl http://localhost:8000/foo
+```
+Access to a route that communicate via https and authenticate with a client certificate:
+```
+curl http://localhost:8000/bar
+```
+Access to the traefik dashboard
+```
+curl http://localhost:8080/dashboard/#/
+```
+
+To play the demo environnement run:
+```bash
+make run_tlsauth
+```
+
+Note:
+> Traefik need to be restart if certificates are regenerated after his launch

+# Example
+## Using Trusted IP (ex: LAN OR VPN) that won't get filtered by crowdsec
+
+You need to configure your Traefik to trust Forwarded headers by your front proxy
+In the example we use a whoami container protected by crowdsec, and we ban our IP before allowing using TrustedIPs
+
+If you are using another proxy in front, you need to add its IP in the trusted IP for the forwarded headers.
+This helps Traefik choose the right IP of the client: see https://doc.traefik.io/traefik/routing/entrypoints/#forwarded-headers
+The "internal" Traefik instance is configured to trust the forward headers
+```yaml
+  - "--entrypoints.web.forwardedheaders.trustedips=172.21.0.5"
+```
+
+We configure the middleware to trust as well as the IP of the intermediate proxy if needed:
+```yaml
+    - "traefik.http.middlewares.crowdsec.plugin.bouncer.forwardedheaderstrustedips=172.21.0.5"
+```
+
+Add your IP to the ban list
+```bash
+docker exec crowdsec cscli decisions add --ip 10.0.10.30 -d 10m
+```
+You should get a 403 on http://localhost/foo
+
+> Replace *10.0.10.30* by your IP
+
+Add the IPs that will not be filtered by the plugin
+```yaml
+    - "traefik.http.middlewares.crowdsec.plugin.bouncer.clientTrustedips=10.0.10.30/32"
+```
+
+> Replace *10.0.10.30/32* by your IP or IP range, so it's not getting checked against ban cache of crowdsec
+
+You should get a 200 on http://localhost/foo even if you are on the ban cache
+
+To play the demo environment run:
+```bash
+make run_trustedips
+```

+          notices within Derivative Works that You distribute, alongside

+          that such additional attribution notices cannot be construed

+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

+# simpleredis
+Minimal go redis with only `get`, `set` and `delete` operation.  
+It supports password authentication with redis.
+With **NO** external dependencies.
+
+## Example
+```go
+import simpleredis "github.com/maxlerebourg/simpleredis"
+
+var redis simpleredis.SimpleRedis
+
+redis.Init("redis:6379", "", "") // redisHost, redisPass, redisDatabase
+
+err := redis.Set("test", []bytes("whatever"), 60),  // Set key "test" with "whatever" for 60 seconds
+if err != nil {
+  ...
+}
+val, err := redis.Get("test") // get key test
+if err != nil {
+  // err could be only redis:unreachable, redis:miss or redis:timeout available in simpleredis.RedisUnreachable
+  ...
+}
+err = redis.Del("test")
+if err != nil {
+  ...
+}
+```
