Basic config examples for Injection Protection

By Kong Inc.
You are browsing unreleased documentation.

Basic configuration examples

The following examples provide some typical configurations for enabling the injection-protection plugin on a service.

Make the following request:

curl -X POST http://localhost:8001/services/{serviceName|Id}/plugins \
    --header "accept: application/json" \
    --header "Content-Type: application/json" \
    --data '
    {
  "name": "injection-protection",
  "config": {
    "injection_types": [
      "sql"
    ],
    "locations": [
      "path_and_query"
    ],
    "enforcement_mode": "block",
    "error_status_code": 400,
    "error_message": "Bad Request"
  }
}
    '

Replace SERVICE_NAME|ID with the id or name of the service that this plugin configuration will target.

Make the following request, substituting your own access token, region, control plane ID, and service ID:

curl -X POST \
https://{us|eu}.api.konghq.com/v2/control-planes/{controlPlaneId}/core-entities/services/{serviceId}/plugins \
    --header "accept: application/json" \
    --header "Content-Type: application/json" \
    --header "Authorization: Bearer TOKEN" \
    --data '{"name":"injection-protection","config":{"injection_types":["sql"],"locations":["path_and_query"],"enforcement_mode":"block","error_status_code":400,"error_message":"Bad Request"}}'

See the Konnect API reference to learn about region-specific URLs and personal access tokens.

First, create a KongPlugin resource:

echo "
apiVersion: configuration.konghq.com/v1
kind: KongPlugin
metadata:
  name: injection-protection-example
plugin: injection-protection
config:
  injection_types:
  - sql
  locations:
  - path_and_query
  enforcement_mode: block
  error_status_code: 400
  error_message: Bad Request
" | kubectl apply -f -

Next, apply the KongPlugin resource to an ingress by annotating the service as follows:

kubectl annotate service SERVICE_NAME konghq.com/plugins=injection-protection-example

Replace SERVICE_NAME with the name of the service that this plugin configuration will target. You can see your available ingresses by running kubectl get service.

Note: The KongPlugin resource only needs to be defined once and can be applied to any service, consumer, or route in the namespace. If you want the plugin to be available cluster-wide, create the resource as a KongClusterPlugin instead of KongPlugin.

Add this section to your declarative configuration file:

plugins:
- name: injection-protection
  service: SERVICE_NAME|ID
  config:
    injection_types:
    - sql
    locations:
    - path_and_query
    enforcement_mode: block
    error_status_code: 400
    error_message: Bad Request

Replace SERVICE_NAME|ID with the id or name of the service that this plugin configuration will target.

Prerequisite: Configure your Personal Access Token 
terraform {
  required_providers {
    konnect = {
      source  = "kong/konnect"
    }
  }
}

provider "konnect" {
  personal_access_token = "kpat_YOUR_TOKEN"
  server_url            = "https://us.api.konghq.com/"
}

Add the following to your Terraform configuration to create a Konnect Gateway Plugin:

resource "konnect_gateway_plugin_injection_protection" "my_injection_protection" {
  enabled = true

  config = {
    injection_types = ["sql"]
    locations = ["path_and_query"]
    enforcement_mode = "block"
    error_status_code = 400
    error_message = "Bad Request"
  }

  control_plane_id = konnect_gateway_control_plane.my_konnect_cp.id
  service = {
    id = konnect_gateway_service.my_service.id
  }
}

The following examples provide some typical configurations for enabling the injection-protection plugin on a route.

Make the following request:

curl -X POST http://localhost:8001/routes/{routeName|Id}/plugins \
    --header "accept: application/json" \
    --header "Content-Type: application/json" \
    --data '
    {
  "name": "injection-protection",
  "config": {
    "injection_types": [
      "sql"
    ],
    "locations": [
      "path_and_query"
    ],
    "enforcement_mode": "block",
    "error_status_code": 400,
    "error_message": "Bad Request"
  }
}
    '

Replace ROUTE_NAME|ID with the id or name of the route that this plugin configuration will target.

Make the following request, substituting your own access token, region, control plane ID, and route ID:

curl -X POST \
https://{us|eu}.api.konghq.com/v2/control-planes/{controlPlaneId}/core-entities/routes/{routeId}/plugins \
    --header "accept: application/json" \
    --header "Content-Type: application/json" \
    --header "Authorization: Bearer TOKEN" \
    --data '{"name":"injection-protection","config":{"injection_types":["sql"],"locations":["path_and_query"],"enforcement_mode":"block","error_status_code":400,"error_message":"Bad Request"}}'

See the Konnect API reference to learn about region-specific URLs and personal access tokens.

First, create a KongPlugin resource:

echo "
apiVersion: configuration.konghq.com/v1
kind: KongPlugin
metadata:
  name: injection-protection-example
plugin: injection-protection
config:
  injection_types:
  - sql
  locations:
  - path_and_query
  enforcement_mode: block
  error_status_code: 400
  error_message: Bad Request
" | kubectl apply -f -

Next, apply the KongPlugin resource to an ingress by annotating the ingress as follows:

kubectl annotate ingress INGRESS_NAME konghq.com/plugins=injection-protection-example

Replace INGRESS_NAME with the name of the ingress that this plugin configuration will target. You can see your available ingresses by running kubectl get ingress.

Note: The KongPlugin resource only needs to be defined once and can be applied to any service, consumer, or route in the namespace. If you want the plugin to be available cluster-wide, create the resource as a KongClusterPlugin instead of KongPlugin.

Add this section to your declarative configuration file:

plugins:
- name: injection-protection
  route: ROUTE_NAME|ID
  config:
    injection_types:
    - sql
    locations:
    - path_and_query
    enforcement_mode: block
    error_status_code: 400
    error_message: Bad Request

Replace ROUTE_NAME|ID with the id or name of the route that this plugin configuration will target.

Prerequisite: Configure your Personal Access Token 
terraform {
  required_providers {
    konnect = {
      source  = "kong/konnect"
    }
  }
}

provider "konnect" {
  personal_access_token = "kpat_YOUR_TOKEN"
  server_url            = "https://us.api.konghq.com/"
}

Add the following to your Terraform configuration to create a Konnect Gateway Plugin:

resource "konnect_gateway_plugin_injection_protection" "my_injection_protection" {
  enabled = true

  config = {
    injection_types = ["sql"]
    locations = ["path_and_query"]
    enforcement_mode = "block"
    error_status_code = 400
    error_message = "Bad Request"
  }

  control_plane_id = konnect_gateway_control_plane.my_konnect_cp.id
  route = {
    id = konnect_gateway_route.my_route.id
  }
}

A plugin which is not associated to any service, route, consumer, or consumer group is considered global, and will be run on every request.

  • In self-managed Kong Gateway Enterprise, the plugin applies to every entity in a given workspace.
  • In self-managed Kong Gateway (OSS), the plugin applies to your entire environment.
  • In Konnect, the plugin applies to every entity in a given control plane.

Read the Plugin Reference and the Plugin Precedence sections for more information.

The following examples provide some typical configurations for enabling the Injection Protection plugin globally.

Make the following request:

curl -X POST http://localhost:8001/plugins/ \
    --header "accept: application/json" \
    --header "Content-Type: application/json" \
    --data '
    {
  "name": "injection-protection",
  "config": {
    "injection_types": [
      "sql"
    ],
    "locations": [
      "path_and_query"
    ],
    "enforcement_mode": "block",
    "error_status_code": 400,
    "error_message": "Bad Request"
  }
}
    '

Make the following request, substituting your own access token, region, and control plane ID:

curl -X POST \
https://{us|eu}.api.konghq.com/v2/control-planes/{controlPlaneId}/core-entities/plugins/ \
    --header "accept: application/json" \
    --header "Content-Type: application/json" \
    --header "Authorization: Bearer TOKEN" \
    --data '{"name":"injection-protection","config":{"injection_types":["sql"],"locations":["path_and_query"],"enforcement_mode":"block","error_status_code":400,"error_message":"Bad Request"}}'

See the Konnect API reference to learn about region-specific URLs and personal access tokens.

Create a KongClusterPlugin resource and label it as global:

apiVersion: configuration.konghq.com/v1
kind: KongClusterPlugin
metadata:
  name: <global-injection-protection>
  annotations:
    kubernetes.io/ingress.class: kong
  labels:
    global: "true"
config:
  injection_types:
  - sql
  locations:
  - path_and_query
  enforcement_mode: block
  error_status_code: 400
  error_message: Bad Request
plugin: injection-protection

Add a plugins entry in the declarative configuration file:

plugins:
- name: injection-protection
  config:
    injection_types:
    - sql
    locations:
    - path_and_query
    enforcement_mode: block
    error_status_code: 400
    error_message: Bad Request
Prerequisite: Configure your Personal Access Token 
terraform {
  required_providers {
    konnect = {
      source  = "kong/konnect"
    }
  }
}

provider "konnect" {
  personal_access_token = "kpat_YOUR_TOKEN"
  server_url            = "https://us.api.konghq.com/"
}

Add the following to your Terraform configuration to create a Konnect Gateway Plugin:

resource "konnect_gateway_plugin_injection_protection" "my_injection_protection" {
  enabled = true

  config = {
    injection_types = ["sql"]
    locations = ["path_and_query"]
    enforcement_mode = "block"
    error_status_code = 400
    error_message = "Bad Request"
  }

  control_plane_id = konnect_gateway_control_plane.my_konnect_cp.id
}
