AM release notes

Changes in AM 7.1.x

Critical changes in AM 7.1

Decompressed JWTs

By default, AM rejects any JWT that expands to more than 32 KiB (32768 bytes) when decompressed.

For information about changing this default value, refer to Controlling the Maximum Size of Compressed JWTs.

Maximum request body size

By default, AM rejects incoming requests with a body larger than 1 MB (1048576 bytes) in size, and returns an HTTP 413 error response.

For information about changing the default value, refer to Limiting the Size of the Request Body.

OAuth 2.0 and OpenID Connect clients

This change affects AM when acting as an OAuth 2.0 or OpenID Connect client.

If a redirection URI uses a scheme, host, or port that differs from that of AM, add it to the Validation Service to ensure that it is pre-approved.

Otherwise, AM rejects the URI, and redirection fails. For details, refer to Configuring Success and Failure Redirection URLs.

Retry Limit Decision node

The new Save Retry Limit to User option in this node is disabled by default after upgrade. For security reasons, it is strongly recommended that you enable this option after upgrade. Enabling the option requires an update to the identity store schema.

One-time passwords stored in transient state

One-time passwords created by the HOTP Generator node are now stored in the authentication tree’s transient state, instead of in the shared state.

Modify any custom authentication nodes or scripts used by the Scripted Decision node to retrieve the one-time passwords from the transient state after upgrading.

Changes to OAuth 2.0 and OIDC script bindings

The format for the following script bindings changed for this release:

requestUri

Old format: String

New format: String with query parameters; for example, http://openam.example.com:8080/openam/oauth2/authorize?test=test

requestParams

Old format: String

New format: Each parameter is returned as an array; for example, grant_type:[authorization_code]

Important changes in AM 7.1.x

AM 7.1.3
OAuth 2.0 introspection changes

HTTP GET requests are now disallowed on the /oauth2/introspect endpoint by default. Using token as a query parameter on this endpoint is also disallowed. To change this behavior to suit existing clients, use the org.forgerock.openam.introspect.token.query.param.allowed advanced server property.

Base URL X-Forwarded-* headers

Previously, if you set the Base URL source to X-Forwarded-* headers and no X-Forwarded-Proto header was provided, the generated URL would have a protocol of null, for example null://host, which would result in a broken URL.

From this release, if no X-Forwarded-Proto header is provided, a fallback scheme is used, based on the URI of the request.

  • You can now specify a port in the Base URL, using the X-Forwarded-Port header.

  • If multiple X-Forwarded-Host headers are specified, the outermost proxy host is used.

AM 7.1.2
Java agent property name changes

The Java agent property names have changed in the AM admin UI. The new names reflect the names now used in the Java agent documentation.

AM 7.1.1
Connections made by the CTS

OPENAM-13855 corrected an issue where the CTS was creating too many connections to the Directory Services. This fix might imply that the number of connections created is now different in your deployment, corrected to be the expected number of connections. Monitor your environments to ensure that this corrected number of connections is sufficient, and increase it if necessary.

Delegated admin can now query user profile attributes

Admin privileges have been changed to let a delegated admin read user profile attributes. For example, this request returns the OAuth 2.0 applications that have been authorized by the demo user:

curl --request GET \
'http://openam.example.com:8443/openam/json/users/demo/oauth2/applications?_queryFilter=true'
OAuth 2.0 token introspection

The OAuth2 token introspection response is now compliant with RFC 7662 and returns a username rather than a user_id.

The expires_in value returned from OAuth 2.0 endpoints

AM 7.1.1 changes the way the /oauth2/introspect and the /oauth2/tokeninfo endpoints return the value of the expires_in object.

The expires_in object specifies the time, in seconds, that a token is valid for. For example, 3600 seconds. This value is set at token creation time, and it depends on the configuration of the OAuth2 Provider Service.

When providing a token introspection or token information response, earlier versions of AM returned the value of the expires_in object as it was stored in the token. This means that any call to the endpoints while the token is valid returned the same value for the expires_in object.

AM 7.1.1 calculates the amount of seconds the token is still valid for and returns this value in the expires_in object. Therefore, repeated calls to the endpoints return different values for the object.

However, the actual value of the expires_in object in the token does not change. Inspecting the token without using AM will show the value set at token creation time.

The expires_in object is not always present in the endpoint response:

Introspection endpoint

AM only returns the expires_in object for client-based tokens issued to a client configured in the same realm as the resource owner’s.

Token information endpoint

AM does not return the expires_in object for client-based tokens issued to a client configured in a different realm than the resource owner’s.
The OIDC /oauth2/userinfo endpoint return values

AM 7.1.1 changes when the aud and iss objects are returned in the JWT response of the OIDC /oauth2/userinfo endpoint.

Earlier versions of AM returned the iss object when the user information response was a signed, encrypted, or a signed and encrypted JWT. The aud object was never returned.

AM 7.1.1 now returns both the aud and iss objects when response is a signed, or a signed and encrypted JWT, according to the OpenID Connect Core 1.0 incorporating errata set 1 specification.

The iss object is no longer returned when the response is an encrypted JWT.

AM 7.1
AM-SESSION-DESTROYED no longer logged

In previous AM releases, session timeout triggered two events. This could cause AM to send two logout tokens on a timeout, if an OAuth 2.0 client was registered for back-channel logout notifications on the session.

With this change, a session is still destroyed on timeout but this is done as part of the timeout event, and the AM-SESSION-DESTROYED activity is not logged.

SAML v2.0 IdP discovery service redirection URLs

The IdP discovery service now includes a mandatory field to configure valid redirection URLs; for example, the URLs of the SPs configured in the CoT to which the discovery service belongs.

After upgrading to AM 7.1, you must:

  • Redeploy the IdP discovery application and reconfigure it to include the valid redirection URLs.

  • Configure the valid redirection URLs in the Validation Service of each of the IdPs, in the Top Level Realm.

For more information, refer to:

Example remote consent service and secret stores

The remote consent service example has been migrated to use AM’s secret store functionality.

As part of this change, the signing and encryption fields have been removed in the global and realm service configurations. The following secret IDs have been created in their place:

For details, refer to The Remote Consent Service.

If you configured the remote consent service example before upgrading, the upgrade process will migrate any secret configuration available to global or realm secret stores.

sub claim in access and ID tokens

The subject claim of access tokens and ID tokens has changed formats to ensure that it is locally unique, as required by the OpenID Connect specification. The new Backchannel logout tokens also use the new format.

The subject claim is in the format (type!subject), where:

  • subject is the identifier of the user/identity, or the name of the OAuth 2.0/OpenID Connect client that is the subject of the token.

  • type can be one of the following:

    • age. Specifies that the subject is an OAuth 2.0/OpenID Connect-related user-agent or client. For example, an OAuth 2.0 client, a Remote Consent Service agent, and a Web and Java Agent internal client.

    • usr. Specifies that the subject is a user/identity.

      For example, (usr!demo), or (age!myOAuth2Client).

Clients that use the sub claim to determine the identity about which the token asserts information are impacted by this change.

To make transitioning to the new format easier, AM 7.1 also includes the following:

  • A new advanced server property, org.forgerock.security.oauth2.enforce.sub.claim.uniqueness.

    This property controls whether AM should create tokens using the new sub claim format or not, and it is disabled after an upgrade to AM 7.1, and enabled in new installations.

    Tokens using the old sub format will still be accepted after the property is enabled. However, earlier versions of AM cannot read tokens with the new format.

  • A new claim: subname.

    The value of the subname claim matches the value of the sub claim used in versions of AM earlier than 7.1. It also matches the value of the sub claim if you disable the org.forgerock.security.oauth2.enforce.sub.claim.uniqueness property.

    An example of the value of the subname claim is demo, or myOauth2Client.

    AM adds the subname claim to access and logout tokens regardless of the configuration of the new advanced server property. The claim is also available to ID tokens, but it is not included in the OIDC Claims Script. Therefore, AM does not add it to ID tokens by default.

Before you enable the advanced server property, make sure that your clients can use the new sub claim format, or a combination of the sub and the subname claims.

Maximum size of decompressed JWTs enforced

A number of AM features accept JWTs to receive information. Some examples are:

  • The Remote Consent service, when it receives consent responses.

  • The OAuth 2.0/OpenID Connect authorization service, when:

    • OpenID Connect clients send request parameters as an encrypted JWT instead of as HTTP parameters.

    • OpenID Connect clients register dynamically using software statements.

  • The Authentication service, when configured to issue client-based sessions.

These JWTs that AM receives can be signed and/or encrypted. Sometimes, if they are fairly large, they can also be compressed so that requests reach AM faster. Decompressing a JWT makes it expand in size. By default, AM 7.1 rejects any JWT that expands to more than 32 KiB (32768 bytes). Before upgrade, ensure that the decompressed JWTs your clients send to AM are smaller than 32 KiB before compression.

If they are not, change the default value to a larger number after upgrade. For information about changing the default value, refer to Controlling the Maximum Size of Compressed JWTs.

Maximum request body size

Application servers can usually mitigate against DoS attacks that POST large amounts of form data, but AM endpoints may receive large amounts of POST data in different ways, such as in JSON, JWT, or JWK formats.

By default, AM 7.1 rejects incoming requests with a body larger than 1 MB (1048576 bytes) in size, and returns an HTTP 413 error response.

For information about changing the default value, refer to Limiting the Size of the Request Body.

OpenID Connect Discovery endpoint disabled by default

The /.well-known/webfinger OpenID Connect discovery endpoint is now disabled by default, and can only be enabled by realm.

To enable the endpoint for a realm, configure the OAuth2 Provider service on the realm and next, enable the new OIDC Provider Discovery switch. Enabling the endpoint for the realm allows searches for users within that realm only.

After upgrading to AM 7.1, the endpoint will be enabled on realms that had the OAuth2 Provider service configured. Disable the endpoint on those realms that are not using OpenID Connect discovery.

For details, refer to OpenID Connect Discovery.

OAuth 2.0 and OpenID Connect clients

AM 7.1 returns an error if the administrator tries to save a client configuration containing an unsupported signing or encryption algorithm.

For example, upon saving the configuration, AM will return an error if there is a typo on an algorithm, or a symmetric signing or encryption algorithm is configured on a public client: these algorithms are derived from the client’s secret, which public clients do not have.

Clients registering dynamically must also send supported algorithms as part of their configuration, or AM will reject the registration request.

Different features support different algorithms. Refer to the documentation or to the UI for more information.

The following are examples of the errors:

  • Unknown encryption algorithm configured for User info encrypted response algorithm

  • Symmetric encryption algorithm configured for ID Token Encryption Algorithm is not allowed for a public client

The error messages are also logged at ERROR level, and identify the client ID to which the error relates.

One-time passwords stored in transient state

One-time passwords created by the HOTP Generator node are now stored in the authentication tree’s transient state, instead of in the shared state.

Modify any custom authentication nodes or scripts used by the Scripted Decision node to retrieve the one-time passwords from the transient state after upgrading to AM 7.1.

For details, refer to Storing Values in a Tree’s Node States.

Changes to the TreeContext class

AM 7.1 introduces the following changes to the TreeContext class:

  • New method added to preserve the secureState for internal nodes contained in a Page node: public TreeContext copyWithCallbacksAndState(JsonValue sharedState, JsonValue transientState, JsonValue secureState, List<? extends Callback> callbacks)

  • New method added to provide nodes with access to secureState: public TreeContext copyWithCallbacks(List<? extends Callback> callbacks)
