Authentication via OAuth2/SAML2

OAuth2/SAML2 let users authenticate against enterprise directories.

Auth0

In the same way as with other identity providers, it’s now possible to leverage Auth0 to authenticate users on DefectDojo.

  1. Inside your Auth0 dashboard create a new application (Applications / Create Application / Single Page Web Application).

  2. On the new application set the following fields:

  3. Copy the following info from the application:

    • Domain
    • Client ID
    • Client Secret
  4. Now, edit the settings (see Configuration) with the following information:

        DD_SOCIAL_AUTH_AUTH0_OAUTH2_ENABLED=True
        DD_SOCIAL_AUTH_AUTH0_KEY=(str, '**YOUR_CLIENT_ID_FROM_STEP_ABOVE**'),
        DD_SOCIAL_AUTH_AUTH0_SECRET=(str,'**YOUR_CLIENT_SECRET_FROM_STEP_ABOVE**'),
        DD_SOCIAL_AUTH_AUTH0_DOMAIN=(str, '**YOUR_AUTH0_DOMAIN_FROM_STEP_ABOVE**'),
        
  5. Restart DefectDojo, and you should now see a Login with Auth0 button on the login page.

Google

New to DefectDojo, a Google account can now be used for Authentication, Authorization, and a DefectDojo user. Upon login with a Google account, a new user will be created if one does not already exist. The criteria for determining whether a user exists is based on the users username. In the event a new user is created, the username is that of the Google address without the domain. Once created, the user creation process will not happen again as the user is recalled by its username, and logged in. In order to make the magic happen, a Google authentication server needs to be created. Closely follow the steps below to guarantee success.

  1. Navigate to the following address and either create a new account, or login with an existing one: Google Developers Console

  2. Once logged in, find the key shaped button labeled Credentials on the left side of the screen. Click Create Credentials, and choose OAuth Client ID:

  3. Select Web Applications, and provide a descriptive name for the client.

    image

  4. Add the pictured URLs in the Authorized Redirect URLs section. This part is very important. If there are any mistakes here, the authentication client will not authorize the request, and deny access.

  5. Once all URLs are added, finish by clicking Create

  6. Now with the authentication client created, the Client ID and Client Secret Key need to be copied over to the settings. Click the newly created client and copy the values:

    image

  7. Edit the settings (see Configuration) with the following information:

        DD_SOCIAL_AUTH_GOOGLE_OAUTH2_ENABLED=True,
        DD_SOCIAL_AUTH_GOOGLE_OAUTH2_KEY=(str, '**YOUR_CLIENT_ID_FROM_STEP_ABOVE**'),
        DD_SOCIAL_AUTH_GOOGLE_OAUTH2_SECRET=(str, '**YOUR_CLIENT_SECRET_FROM_STEP_ABOVE**'),
        

    To authorize users you will need to set the following:

        DD_SOCIAL_AUTH_GOOGLE_OAUTH2_WHITELISTED_DOMAINS = ['example.com', 'example.org']
        

    or

        DD_SOCIAL_AUTH_GOOGLE_OAUTH2_WHITELISTED_EMAILS = ['<email@example.com>']
        

OKTA

In a similar fashion to that of Google, using OKTA as a OAuth2 provider carries the same attributes and a similar procedure. Follow along below.

  1. Navigate to the following address and either create a new account, or login with an existing one: OKTA Account Creation

  2. Once logged in, enter the Applications and click Add Application:

    image

  3. Select Web Applications.

    image

  4. Add the pictured URLs in the Login Redirect URLs section. This part is very important. If there are any mistakes here, the authentication client will not authorize the request, and deny access. Check the Implicit box as well.

    image

  5. Once all URLs are added, finish by clicking Done.

  6. Return to the Dashboard to find the Org-URL. Note this value as it will be important in the settings file.

    image

  7. Now, with the authentication client created, the Client ID and Client Secret Key need to be copied over to the settings. Click the newly created client and copy the values:

    image

  8. Edit the settings (see Configuration) with the following information:

        DD_SOCIAL_AUTH_OKTA_OAUTH2_ENABLED=True,
        DD_SOCIAL_AUTH_OKTA_OAUTH2_KEY=(str, '**YOUR_CLIENT_ID_FROM_STEP_ABOVE**'),
        DD_SOCIAL_AUTH_OKTA_OAUTH2_SECRET=(str, '**YOUR_CLIENT_SECRET_FROM_STEP_ABOVE**'),
        DD_SOCIAL_AUTH_OKTA_OAUTH2_API_URL=(str, 'https://{your-org-url}/oauth2'),
        

If during the login process you get the following error: The ‘redirect_uri’ parameter must be an absolute URI that is whitelisted in the client app settings. and the redirect_uri HTTP GET parameter starts with http:// instead of https:// you need to add SOCIAL_AUTH_REDIRECT_IS_HTTPS = True in the settings.

Azure Active Directory

Azure AD Configuration

You can now use your corporate Azure Active Directory to authenticate users to Defect Dojo. Users will be using your corporate Azure AD account (A.K.A. Office 365 identity) to authenticate via OAuth, and all the conditional access rules and benefits from Azure Active Directory will also apply to the Defect Dojo Authentication. Once the user signs in, it will try to match the UPN of the user to an existing e-mail from a user in Defect Dojo, and if no match is found, a new user will be created in Defect Dojo, associated with the unique id/value of the user provided by your Azure AD tenant. Then, you can assign roles to this user, such as ‘superuser’.

  1. Navigate to the following address and follow instructions to create a new app registration

  2. Once you register an app, take note of the following information:

    • Application (client) ID
    • Directory (tenant) ID
    • Under Certificates & Secrets, create a new Client Secret
  3. Under Authentication > Redirect URIs, add a WEB type of uri where the redirect points to

  4. Edit the settings (see Configuration) with the following information:

        DD_SOCIAL_AUTH_AZUREAD_TENANT_OAUTH2_KEY=(str, 'YOUR_APPLICATION_ID_FROM_STEP_ABOVE'),
        DD_SOCIAL_AUTH_AZUREAD_TENANT_OAUTH2_SECRET=(str, 'YOUR_CLIENT_SECRET_FROM_STEP_ABOVE'),
        DD_SOCIAL_AUTH_AZUREAD_TENANT_OAUTH2_TENANT_ID=(str, 'YOUR_DIRECTORY_ID_FROM_STEP_ABOVE'),
        DD_SOCIAL_AUTH_AZUREAD_TENANT_OAUTH2_ENABLED = True
        
  5. Restart your Dojo, and you should now see a Login with Azure AD button on the login page which should magically work

Automatic Import of User-Groups

To import groups from Azure AD users, the following environment variable needs to be set:

    DD_SOCIAL_AUTH_AZUREAD_TENANT_OAUTH2_GET_GROUPS=True
    

This will ensure the user is added to all the groups found in the Azure AD Token. Any missing groups will be created in DefectDojo (unless filtered). This group synchronization allows for product access via groups to limit the products a user can interact with. Do not activate Emit groups as role claims within the Azure AD “Token configuration”.

To prevent authorization creep, old Azure AD groups a user is not having anymore can be deleted with the following environment parameter:

    DD_SOCIAL_AUTH_AZUREAD_TENANT_OAUTH2_CLEANUP_GROUPS=True
    

To limit the amount of groups imported from Azure AD, a regular expression can be used as the following:

    DD_SOCIAL_AUTH_AZUREAD_TENANT_OAUTH2_GROUPS_FILTER='^team-.*' # or 'teamA|teamB|groupC'
    

Gitlab

In a similar fashion to that of Google and OKTA, using Gitlab as a OAuth2 provider carries the same attributes and a similar procedure. Follow along below.

  1. Navigate to your Gitlab settings page and got to the Applications section

  2. Choose a name for your application

  3. For the Redirect URI, enter the DefectDojo URL with the following format

  4. Edit the settings (see Configuration) with the following information:

        DD_SOCIAL_AUTH_GITLAB_KEY=(str, 'YOUR_APPLICATION_ID_FROM_STEP_ABOVE'),
        DD_SOCIAL_AUTH_GITLAB_SECRET=(str, 'YOUR_SECRET_FROM_STEP_ABOVE'),
        DD_SOCIAL_AUTH_GITLAB_API_URL=(str, 'https://gitlab.com'),
        DD_SOCIAL_AUTH_GITLAB_OAUTH2_ENABLED = True
        

    Additionally, if you want to import your Gitlab projects as DefectDojo products, add the following line to your settings:

        DD_SOCIAL_AUTH_GITLAB_PROJECT_AUTO_IMPORT = True
        
  5. Restart DefectDojo, and you should now see a Login with Gitlab button on the login page.

Keycloak

There is also an option to use Keycloak as OAuth2 provider in order to authenticate users to Defect Dojo, also by using the social-auth plugin.

Here are suggestion on how to configure Keycloak and DefectDojo:

Configure Keycloak

(assuming you already have an existing realm, otherwise create one)

  1. Navigate to your keycloak realm and add a new client of type openid-connect. Choose a name for the client id and use this value below for DD_SOCIAL_AUTH_KEYCLOAK_KEY).
  2. In the client settings:
    • Set access type to confidential
    • Under valid Redirect URIs, add the URI to your defect dojo installation, e.g. ‘https://<YOUR_DD_HOST>/*’
    • Under web origins, add the same (or ‘+')
    • Under Fine grained openID connect configuration -> user info signed response algorithm: set to RS256
    • Under Fine grained openID connect configuration -> request object signature algorithm: set to RS256
    • -> save these settings in keycloak (hit save button)
  3. Under Scope -> Full Scope Allowed set to off
  4. Under mappers -> add a custom mapper here:
    • Name: aud
    • Mapper type: audience
    • Included audience: select your client/client-id here
    • Add ID to token: off
    • Add access to token: on
  5. Under credentials: copy the secret (and use as DD_SOCIAL_AUTH_KEYCLOAK_SECRET below)
  6. In your realm settings -> keys: copy the “Public key” (signing key) (use for DD_SOCIAL_AUTH_KEYCLOAK_PUBLIC_KEY below)
  7. In your realm settings -> general -> endpoints: look into openId endpoint configuration and look up your authorization and token endpoint (use them below)

Configure Defect Dojo

Edit the settings (see Configuration) with the following information:

   DD_SESSION_COOKIE_SECURE=True,
   DD_CSRF_COOKIE_SECURE=True,
   DD_SECURE_SSL_REDIRECT=True,
   DD_SOCIAL_AUTH_KEYCLOAK_OAUTH2_ENABLED=True,
   DD_SOCIAL_AUTH_KEYCLOAK_PUBLIC_KEY=(str, '<your realm public key>'),
   DD_SOCIAL_AUTH_KEYCLOAK_KEY=(str, '<your client id>'), 
   DD_SOCIAL_AUTH_KEYCLOAK_SECRET=(str, '<your keycloak client credentials secret>'), 
   DD_SOCIAL_AUTH_KEYCLOAK_AUTHORIZATION_URL=(str, '<your authorization endpoint>'),
   DD_SOCIAL_AUTH_KEYCLOAK_ACCESS_TOKEN_URL=(str, '<your token endpoint>')         
   

or, alternatively, for helm configuration, add this to the extraConfig section:

DD_SESSION_COOKIE_SECURE: 'True'
DD_CSRF_COOKIE_SECURE: 'True'
DD_SECURE_SSL_REDIRECT: 'True'
DD_SOCIAL_AUTH_KEYCLOAK_OAUTH2_ENABLED: 'True'
DD_SOCIAL_AUTH_KEYCLOAK_PUBLIC_KEY: '<your realm public key>'
DD_SOCIAL_AUTH_KEYCLOAK_KEY: '<your client id>'
DD_SOCIAL_AUTH_KEYCLOAK_SECRET: '<your keycloak client credentials secret>'
DD_SOCIAL_AUTH_KEYCLOAK_AUTHORIZATION_URL: '<your authorization endpoint>'
DD_SOCIAL_AUTH_KEYCLOAK_ACCESS_TOKEN_URL: '<your token endpoint>'

Optionally, you can set DD_SOCIAL_AUTH_KEYCLOAK_LOGIN_BUTTON_TEXT in order to customize the login button’s text caption.

GitHub

  1. Navigate to GitHub.com and follow instructions to create a new OAuth App https://docs.github.com/en/developers/apps/building-oauth-apps/creating-an-oauth-app
  2. Choose a name for your application
  3. For the Redirect URI, enter the DefectDojo URL with the following format
  4. Edit the settings (see Configuration) with the following information:
      
        DD_SOCIAL_AUTH_GITHUB_KEY=(str, 'GitHub OAuth App Client ID'),  
        DD_SOCIAL_AUTH_GITHUB_SECRET=(str, 'GitHub OAuth App Client Secret'),  
        DD_SOCIAL_AUTH_GITHUB_OAUTH2_ENABLED = True  
        
  5. Restart DefectDojo, and you should now see a Login with GitHub button on the login page.

GitHub Enterprise

  1. Navigate to your GitHub Enterprise Server and follow instructions to create a new OAuth App https://docs.github.com/en/enterprise-server/developers/apps/building-oauth-apps/creating-an-oauth-app
  2. Choose a name for your application
  3. For the Redirect URI, enter the DefectDojo URL with the following format
  4. Edit the settings (see Configuration) with the following information:
      
        DD_SOCIAL_AUTH_GITHUB_ENTERPRISE_KEY=(str, 'GitHub Enterprise OAuth App Client ID'),  
        DD_SOCIAL_AUTH_GITHUB_ENTERPRISE_SECRET=(str, 'GitHub Enterprise OAuth App Client Secret'),  
        DD_SOCIAL_AUTH_GITHUB_ENTERPRISE_URL=(str, 'https://github.<your_company>.com/'),  
        DD_SOCIAL_AUTH_GITHUB_ENTERPRISE_API_URL=(str, 'https://github.<your_company>.com/api/v3/'),  
        DD_SOCIAL_AUTH_GITHUB_ENTERPRISE_OAUTH2_ENABLED = True,  
        
  5. Restart DefectDojo, and you should now see a Login with GitHub Enterprise button on the login page.

SAML 2.0

In a similar direction to OAuth, this SAML addition provides a more secure perogative to SSO. For definitions of terms used and more information, see the plugin plugin homepage.

  1. Navigate to your SAML IdP and find your metadata

  2. Edit the settings (see Configuration) with the following information:

        DD_SAML2_ENABLED=(bool, **True**),
        # SAML Login Button Text
        DD_SAML2_LOGIN_BUTTON_TEXT=(str, 'Login with SAML'),
        # If the metadata can be accessed from a url, try the
        DD_SAML2_METADATA_AUTO_CONF_URL=(str, '<https://your_IdP.com/metadata.xml>'),
        # Otherwise, downlaod a copy of the metadata into an xml file, and
        # list the path in DD_SAML2_METADATA_LOCAL_FILE_PATH
        DD_SAML2_METADATA_LOCAL_FILE_PATH=(str, '/path/to/your/metadata.xml'),
        # Fill in DD_SAML2_ATTRIBUTES_MAP to corresponding SAML2 userprofile attributes provided by your IdP
        DD_SAML2_ATTRIBUTES_MAP=(dict, {
            # format: SAML attrib:django_user_model
            'Email': 'email',
            'UserName': 'username',
            'Firstname': 'first_name',
            'Lastname': 'last_name'
        }),
        # May configure the optional fields
        

NOTE: DD_SAML2_ATTRIBUTES_MAP in k8s can be referenced as extraConfig (e.g. DD_SAML2_ATTRIBUTES_MAP: 'Email'='email', 'Username'='username'...)

NOTE: DD_SITE_URL might also need to be set depending on the choices you make with the metadata.xml provider. (File versus URL).

  1. Checkout the SAML section in dojo/dojo/settings/settings.dist.py and verfiy if it fits your requirement. If you need help, take a look at the plugin documentation.

  2. Restart DefectDojo, and you should now see a Login with SAML button (default setting of DD_SAML2_LOGIN_BUTTON_TEXT) on the login page.

NOTE: In the case when IDP is configured to use self signed (private) certificate, than CA needs to be specified by define environments variable REQUESTS_CA_BUNDLE that points to the path of private CA certificate.

Advanced Configuration

The https://github.com/IdentityPython/djangosaml2 plugin has a lot of options. For details take a look at the plugin documentation. All default options in DefectDojo can overwritten in the local_settings.py. If you want to change the organization name, you can add the following lines:

if SAML2_ENABLED:
    SAML_CONFIG['contact_person'] = [{
        'given_name': 'Extra',
        'sur_name': 'Example',
        'company': 'DefectDojo',
        'email_address': 'dummy@defectdojo.com',
        'contact_type': 'technical'
    }]
    SAML_CONFIG['organization'] = {
        'name': [('DefectDojo', 'en')],
        'display_name': [('DefectDojo', 'en')],
    },

Migration from django-saml2-auth

Up to relase 1.15.0 the SAML integration was based on https://github.com/fangli/django-saml2-auth. Which the switch to djangosaml2 some parameters has changed:

  • DD_SAML2_ASSERTION_URL: not necessary any more - automatically generated
  • DD_SAML2_DEFAULT_NEXT_URL: not necessary any more - default forwarding from defectdojo is used
  • DD_SAML2_NEW_USER_PROFILE: not possible any more - default profile is used, see User Permissions
  • DD_SAML2_ATTRIBUTES_MAP: Syntax has changed
  • DD_SAML2_CREATE_USER: Default value changed to False, to avoid security breaches

RemoteUser

This implementation is suitable if the DefectDojo instance is placed behind HTTP Authentication Proxy. Dojo expects that the proxy will perform authentication and pass HTTP requests to the Dojo instance with filled HTTP headers. The proxy should check if an attacker is not trying to add a malicious HTTP header and bypass authentication.

Values which need to be set:

  • DD_AUTH_REMOTEUSER_ENABLED - Needs to be set to True
  • DD_AUTH_REMOTEUSER_USERNAME_HEADER - Name of the header which contains the username
  • DD_AUTH_REMOTEUSER_EMAIL_HEADER(optional) - Name of the header which contains the email
  • DD_AUTH_REMOTEUSER_FIRSTNAME_HEADER(optional) - Name of the header which contains the first name
  • DD_AUTH_REMOTEUSER_LASTNAME_HEADER(optional) - Name of the header which contains the last name
  • DD_AUTH_REMOTEUSER_GROUPS_HEADER(optional) - Name of the header which contains the comma-separated list of groups; user will be assigned to these groups (missing groups will be created)
  • DD_AUTH_REMOTEUSER_GROUPS_CLEANUP(optional) - Same as [#automatic-import-of-user-groups](AzureAD implementation)
  • DD_AUTH_REMOTEUSER_TRUSTED_PROXY - Comma separated list of proxies; Simple IP and CIDR formats are supported
  • DD_AUTH_REMOTEUSER_LOGIN_ONLY(optional) - Check Django documentation

WARNING: There is possible spoofing of headers (for all DD_AUTH_REMOTEUSER_xxx_HEADER values). Read Warning in Django documentation

User Permissions

When a new user is created via the social-auth, only the default permissions are active. This means that the newly created user does not have access to add, edit, nor delete anything within DefectDojo. There are two parameters in the System Settings to influence the permissions for newly created users:

Default group

When both the parameters Default group and Default group role are set, the new user will be a member of the given group with the given role, which will give him the respective permissions.

Login speed-up

You can bypass the login form if you are only using SSO/Social authentication for login in by enabling these two environment variables:

DD_SOCIAL_LOGIN_AUTO_REDIRECT: "true"
DD_SOCIAL_AUTH_SHOW_LOGIN_FORM: "false"

Login form fallback

If you are using “login speed-up”, it can be useful to be able to login by the standard way, for example when an admin user needs to log in because of a change of some settings or permissions. This feature is accessible by a visiting the URL <DD_HOST>/login?force_login_form.

Other Providers

In an effort to accommodate as much generality as possible, it was decided to implement OAuth2 with the social-auth ecosystem as it has a library of compatible providers with documentation of implementation. Conveniently, each provider has an identical procedure of managing the authenticated responses and authorizing access within a given application. The only difficulty is creating a new authentication client with a given OAuth2 provider.
