PerimeterX Express.js Middleware

Latest stable version: v7.9.0

Installation

PerimeterX Express.js middleware is installed via NPM: $ npm install --save perimeterx-node-express

Please note: As stated in NodeJS's release schedule, NodeJS 6.x is reaching EOL. Thus, support for it will be dropped starting with version 5.0.0.

Upgrading

To upgrade to the latest Enforcer version, run:

npm install -s perimeterx-node-express

For more information, contact PerimeterX Support.

Configuration

Required Configuration

To use PerimeterX middleware on a specific route follow this example:

'use strict';

const express = require('express');
const perimeterx = require('perimeterx-node-express');

const server = express();

/* px-module and cookie parser need to be initiated before any route usage */
const pxConfig = {
    px_app_id: 'PX_APP_ID',
    px_cookie_secret: 'PX_COOKIE_ENCRYPTION_KEY',
    px_auth_token: 'PX_TOKEN',
};
perimeterx.init(pxConfig);

/*  block users with high bot scores using px-module for the route /helloWorld */
server.get('/helloWorld', perimeterx.middleware, (req, res) => {
    res.send('Hello from PX');
});

server.listen(8081, () => {
    console.log('server started');
});

The PerimeterX Application ID / AppId and PerimeterX Token / Auth Token can be found in the Portal, in Applications.
The PerimeterX Cookie Encryption Key can be found in the portal, in Policies.

The Policy from where the Cookie Encryption Key is taken must correspond with the Application from where the Application ID / AppId and PerimeterX Token / Auth Token

Setting the PerimeterX middleware on all server's routes:

When configuring the PerimeterX middleware on all the server's routes, you will have a score evaluation on each incoming request. The recommended pattern is to use on top of page views routes.

'use strict';

const express = require('express');
const perimeterx = require('perimeterx-node-express');

const server = express();

/* the px-module and parser need to be initialized before any route usage */
const pxConfig = {
    px_app_id: 'PX_APP_ID',
    px_cookie_secret: 'PX_COOKIE_ENCRYPTION_KEY',
    px_auth_token: 'PX_TOKEN',
};
perimeterx.init(pxConfig);

/* block high scored users using px-module for all routes */
server.use(perimeterx.middleware);

server.get('/helloWorld', (req, res) => {
    res.send('Hello from PX');
});

server.listen(8081, () => {
    console.log('server started');
});

Upgrading

To upgrade to the latest Enforcer version, run:

npm install -s perimeterx-node-express

Your Enforcer version is now upgraded to the latest enforcer version.

    ...
  }
  ...
};

Enrich Custom Parameters

An array of HTTP methods that are always filtered and not validated by the PerimeterX middleware.

Default: Empty

const pxConfig = {
  ...
  px_filter_by_http_method: ['options']
  ...
};

Test Block Flow on Monitoring Mode

Allows you to test an enforcer’s blocking flow while you are still in Monitor Mode.

When the header name is set(eg. x-px-block) and the value is set to 1, when there is a block response (for example from using a User-Agent header with the value of PhantomJS/1.0) the Monitor Mode is bypassed and full block mode is applied. If one of the conditions is missing you will stay in Monitor Mode. This is done per request. To stay in Monitor Mode, set the header value to 0.

The Header Name is configurable using the px_bypass_monitor_header property.

Default: Empty

const pxConfig = {
  ...
  px_bypass_monitor_header: "x-px-block"
  ...
};

CSP Enabled

Used in cdMiddleware - Code Defender's middleware. Enable enforcement of CSP header policy on responses retured to the client (only if active CSP policy exists in PerimeterX for the specific appId).

Default: false

const pxConfig = {
  ...
  px_csp_enabled: false
  ...
};

CSP Policy Refresh Interval

Used by cdMiddleware - Code Defender's middleware. Sets the interval, in minutes, to fetch and update the active CSP policy for the specific appId from PerimeterX.

Default: 5

const pxConfig = {
  ...
  px_csp_policy_refresh_interval_minutes: 5
  ...
};

CSP Invalidate Policy Interval

Used by cdMiddleware - Code Defender's middleware. Invalidates active CSP policy after specified number of minutes with no updates received from PerimeterX.

Default: 60

const pxConfig = {
  ...
  px_csp_no_updates_max_interval_minutes: 60
  ...
};

Login Credentials Extraction

This feature extracts credentials (hashed username and password) from requests and sends them to PerimeterX as additional info in the risk api call. The feature can be toggled on and off, and may be set for any number of unique paths.

If credentials are found to be compromised, the header px-compromised-credentials will be added to the request with the value 1. You may configure the name of this header with the px_compromised_credentials_header configuration.

Note: This feature requires access to the request body as a either an object or a string type.

Default Values

px_compromised_credentials_header: "px-compromised-credentials"

px_login_credentials_extraction_enabled: false

px_login_credentials_extraction: Empty

const pxConfig = {
  ...
  px_compromised_credentials_header: "x-px-comp-creds",
  px_login_credentials_extraction_enabled: true,
  px_login_credentials_extraction: [
    {
      path: "/login", // login path
      method: "post", // supported values: post
      sent_through: "body", // supported values: body, header, query-param
      pass_field: "password", // name of the password field in the request
      user_field: "username" // name of the username field in the request
    },
    ...
  ],
  ...
};

It is also possible to define a custom callback to extract the username and password. The function should accept the request object as a parameter and return an object with the keys user and pass. If extraction is unsuccessful, the function should return null.

const pxConfig = {
    ...
    px_login_credentials_extraction_enabled: true,
    px_login_credentials_extraction: [{
        path: "/login", // login path, automatically added to sensitive routes
        method: "post", // supported values: post
        callback: (req) => {
            // custom implementation resulting in variables username and password
            if (username && password) {
                return { "user": username, "pass": password };
            } else {
                return null;
            }
        }
    }]
};

JWT

Enable the extraction of JWT fields from requests and adding them to the risk, page requested and block activities.

px_jwt_cookie_name

The cookie name that should contain the JWT token.

Default: ""

px_jwt_cookie_user_id_field_name

The field name in the JWT object, extracted from the JWT cookie, that contains the user ID to be extracted

Default: ""

px_jwt_cookie_additional_field_names

The field names in the JWT object, extracted from the JWT cookie, that should be extracted in addition to the user ID.

Default: []

px_jwt_header_name

The header name that should contain the JWT token.

Default: ""

px_jwt_header_user_id_field_name

The field name in the JWT object, extracted from the JWT header, that contains the user ID to be extracted

Default: ""

px_jwt_header_additional_field_names

The field names in the JWT object, extracted from the JWT header, that should be extracted in addition to the user ID.

Default: []

const pxConfig = {
  ...
    "px_jwt_cookie_name":  "auth",
    "px_jwt_cookie_user_id_field_name": "nameID",
    "px_jwt_cookie_additional_field_names": ["exp", "iss"],
    "px_jwt_header_name":  "authorization",
    "px_jwt_header_user_id_field_name": "sub",
    "px_jwt_header_additional_field_names": ["jti"]
  ...
};

Additional S2S Activity

To enhance detection on login credentials extraction endpoints, the following additional information is sent to PerimeterX via an additional_s2s activity:

Response Code - The numerical HTTP status code of the response. This is sent automatically.
Login Success - A boolean indicating whether the login completed successfully. See the options listed below for how to provide this data.
Raw Username - The original username used for the login attempt. In order to report this information, make sure the configuration px_send_raw_username_on_additional_s2s_activity is set to true.

By default, this additional_s2s activity is sent automatically. If it is preferable to send this activity manually, it's possible to disable automatic sending by configuring the value of px_automatic_additional_s2s_activity_enabled to false.

*Default Value: true

const pxConfig = {
    ...
    px_automatic_additional_s2s_activity_enabled: false
    ...
}

The activity can then be sent manually by invoking the function sendAdditionalS2SActivity(). The function accepts three arguments: the original HTTP request, the status code, and a boolean indicating the login successful status.

const perimeterx = require('perimeterx-node-express');
const pxConfig = {
    px_app_id: '<APP_ID>',
    // ...
};
pxInstance = perimeterx.new(pxConfig);

app.use(pxInstance.middleware);

app.post('/login', (req, res) => {
   // login flow resulting in boolean isLoginSuccessful
    res.status(200).json({ successful: isLoginSuccessful });
    pxInstance.sendAdditionalS2SActivity(req, res.statusCode, isLoginSuccessful);
});

Login Success Reporting

There are a number of different possible ways to report the success or failure of the login attempt. If left empty, the login successful status will always be reported as false.

Default: Empty

const pxConfig = {
    ...
    px_login_successful_reporting_method: 'status' // supported values: status, header, body, custom
    ...
}

Status

Provide a status or array of statuses that represent a successful login. If a response's status code matches the provided value or one of the values in the provided array, the login successful status is set to true. Otherwise, it's set to false.

Note: To define a range of statuses, use the custom reporting method.

Default Values

px_login_successful_status: 200

const pxConfig = {
    ...
    px_login_successful_reporting_method: 'status',
    px_login_successful_status: [200, 202] // number or array of numbers
    ...
}

Header

Provide a header name and value. If the header exists on the response and matches the provided value, the login successful status is set to true. If the header is not found on the response, or if the header value does not match the value in the configuration, the login successful status is set to false.

Default Values

px_login_successful_header_name: x-px-login-successful

px_login_successful_header_value: 1

const pxConfig = {
    ...
    px_login_successful_reporting_method: 'header',
    px_login_successful_header_name: 'login-successful',
    px_login_successful_header_value: 'true'
    ...
}

Body

Provide a string or regular expression with which to parse the response body. If a match is found, the login successful status is set to true. If no match is found, the login successful status is set to false.

Default Values

px_login_successful_body_regex: Empty

const pxConfig = {
    ...
    px_login_successful_reporting_method: 'body',
    px_login_successful_body_regex: 'You logged in successfully!' // string or RegExp
    ...
}

Custom

Provide a custom callback that returns a boolean indicating if the login was successful.

Default Values px_login_successful_custom_callback: null

const pxConfig = {
    ...
    px_login_successful_reporting_method: 'custom',
    px_login_successful_custom_callback: (response) => {
        return response && response.locals && response.locals.isLoginSuccessful;
    }
    ...
}

Raw Username

When enabled, the raw username used for logins on login credentials extraction endpoints will be reported to PerimeterX if (1) the credentials were identified as compromised, and (2) the login was successful as reported via the property above.

Default: false

const pxConfig = {
    ...
    px_send_raw_username_on_additional_s2s_activity: true
    ...
}

CORS Support

Enable CORS support for the enforcer. This will allow the enforcer to filter out preflight requests and to add CORS headers to block responses. This will ensure responses are not blocked by the browser. CORS support is enabled by default.

px_cors_support_enabled - Enable CORS support for the enforcer.

Default: false

px_cors_custom_preflight_handler - Custom preflight handler. This function will be called for preflight requests and returns response that will return to the client.

// Example
const pxConfig = { 
    ...
    px_cors_custom_preflight_handler: function(request) {
        const response = {
            status: '204',
        };
    
        response.headers = {
            'Access-Control-Allow-Origin': request.headers['origin'] || '*',
            'Access-Control-Allow-Methods': request.method,
            'Access-Control-Allow-Headers': request.headers['access-control-request-headers'],
            'Access-Control-Allow-Credentials': 'true',
            'Access-Control-Max-Age': '86400',
        };
    
        return response;
    };
}

px_cors_preflight_request_filter_enabled - Filter out preflight requests from validation flow.

Default: false

Enable CORS support for the enforcer:

const pxConfig = {
  ...
  px_cors_support_enabled: true,
  px_cors_preflight_request_filter_enabled: true,
  ...
};

The default CORS policy when blocking a request is as follows:

Access-Control-Allow-Origin: request origin
Access-Control-Allow-Credentials: true

The default CORS policy can be overridden by setting the following properties:

px_cors_create_custom_block_response_headers

Synchronous function supplied by the customer which gets the original request and returns an array of custom headers to be added to the block response. Return type should be an array of objects as follows:

// Example
const pxConfig = {
  ...
      px_cors_create_custom_block_response_headers: function(request) { 
            return {
                'Access-Control-Allow-Origin':  request.headers['origin'],
                'Access-Control-Allow-Methods': 'GET, POST, OPTIONS',
                'Access-Control-Allow-Headers': 'Content-Type, Authorization',
                'Access-Control-Allow-Credentials': 'true'
            }
        };
  ...
};

Custom Is Sensitive Request

Allows writing your own logic to decide whether the request is sensitive. The custom sensitive request function gets the request object as a parameter and should return true, otherwise, return false. Throwing an exception is equivalent to false.

Default: Empty

const pxConfig = {
    ...
        px_custom_is_sensitive_request: function(req) {
            return req.method === 'POST' && req.body && req.body.test;
        }
    ...

Default: null

Code Defender Middleware - cdMiddleware

Code Defender's middleware to handle the enforcement of CSP headers on responses returned to the client. The express module is in charge of communicating with PerimeterX to receive and maintain the latest CSP policy for the given appId. It also maintains the policy state and invalidates the policy when communication with PerimeterX's Enforcer Data Provider is lost, base on the configuration values (px_csp_no_updates_max_interval_minutes, px_csp_policy_refresh_interval_minutes).

It then uses PerimeterX Node Core module to enforce the actual functionality adding the necessary CSP header to the response object.

usage example:

const perimeterx = require('perimeterx-node-express');
...
const pxInstance = perimeterx.new(pxConfig);
app.use(pxInstance.cdMiddleware);
...

Adding Nonce value to CSP header

The PerimeterX Express module allows adding a Nonce value to the CSP header. To do this, use the module's static function addNonce. After PerimeterX cdMiddleware has added the CSP header to the response, call the addNonce function, passing in the response object and a nonce value (string consisting of alphanumeric characters). If a CSP header exists on the response object, the function will alter the header by adding the nonce value in the correct place. The function does not return a value, but rather changes the original response.

const perimeterx = require('perimeterx-node-express');
...
perimeterx.addNonce(response, 'rAnd0mNon6e');
...

Please note: the nonce value must be unique for each HTTP response. For further explanation, refer to the official documentation of CSP nonce.

Advanced Blocking Response

In special cases, (such as XHR post requests) a full Captcha page render might not be an option. In such cases, using the Advanced Blocking Response returns a JSON object continaing all the information needed to render your own Captcha challenge implementation, be it a popup modal, a section on the page, etc. The Advanced Blocking Response occurs when a request contains the Accept header with the value of application/json. A sample JSON response appears as follows:

{
    "appId": String,
    "jsClientSrc": String,
    "firstPartyEnabled": Boolean,
    "vid": String,
    "uuid": String,
    "hostUrl": String,
    "blockScript": String
}

Once you have the JSON response object, you can pass it to your implementation (with query strings or any other solution) and render the Captcha challenge.

In addition, you can add the _pxOnCaptchaSuccess callback function on the window object of your Captcha page to react according to the Captcha status. For example when using a modal, you can use this callback to close the modal once the Captcha is successfullt solved.
An example of using the _pxOnCaptchaSuccess callback is as follows:

window._pxOnCaptchaSuccess = function (isValid) {
    if (isValid) {
        alert('yay');
    } else {
        alert('nay');
    }
};

For details on how to create a custom Captcha page, refer to the documentation

If you wish to disable this behavior when the Accept header has the value of application/json, set the following configuration:
const pxConfig = {
  ...
  px_advanced_blocking_response_enabled: false
  ...
};

Multiple App Support

If you use two different apps on the same node runtime, you can create two instances and use them on two routes:

'use strict';

const express = require('express');
const perimeterx = require('perimeterx-node-express');

const server = express();

/* the px-module and parser need to be initialized before any route usage */
const pxConfig1 = {
    px_app_id: 'PX_APP_ID_1',
    px_cookie_secret: 'PX_COOKIE_ENCRYPTION_KEY',
    px_auth_token: 'PX_TOKEN_1',
};
const middlewareApp1 = perimeterx.new(pxConfig1).middleware;
const app1Router = express.Router();
app1Router.use(middlewareApp1);
app1Router.get('/hello', (req, res) => {
    res.send('Hello from App1');
});
server.use('/app1', app1Router);

const pxConfig2 = {
    px_app_id: 'PX_APP_ID_2',
    px_cookie_secret: 'PX_COOKIE_ENCRYPTION_KEY',
    px_auth_token: 'PX_TOKEN_2',
};
const middlewareApp2 = perimeterx.new(pxConfig2).middleware;
const app2Router = express.Router();
app2Router.use(middlewareApp2);
app2Router.get('/app2', (req, res) => {
    res.send('Hello from App2');
});
server.use('/app2', app1Router);

server.listen(8081, () => {
    console.log('server started');
});

## <a name=“additionalInformation”></a> Additional Information

### URI Delimiters

PerimeterX processes URI paths with general- and sub-delimiters according to RFC 3986. General delimiters (e.g., `?`, `#`) are used to separate parts of the URI. Sub-delimiters (e.g., `$`, `&`) are not used to split the URI as they are considered valid characters in the URI path.
