SSO 8.8.1 (21/06/2021)
Corrections
IDS-3125 - Cross-site scripting (XSS) vulnerability has been corrected in error template
SSO 8.8.0 (09/06/2021)
New Features
IDS-105 - Administrators are now able to configure OpenID Connect methods in SSO Management UI without using the Management API. Read our Knowledge base article Configure OpenID Connect authentication method in SSO Management UI
IDS-2861 - UserInfo endpoint now supports POST requests. See Authorization code grant and web single sign-on - SSO for more information
IDS-2765 - SPI OpenID Connect CIBA method has been included to SSO. This allows CIBA method to be used as step-up method for your registered users. Read more about the configuration from OpenID Connect CIBA authentication method
IDS-2937 - New API calls have been added to the Accounting Service to get more information on the ticket granted events happening in your system. The API calls return method and application used for each of the events and are able to be queried daily, hourly or per minute. More information about the API calls can be found from Event details API section in Accounting Service API
IDS-2256 - Freja eID is now supported by SSO. Read our Knowledge base article Configure OpenID Connect Freja eID login

OpenID Connect Core 1.0IDS-3061 - New compatibility flag was introduced to resolve backwards incompatibility with OTP printout and TOTP secrets in the case that the users are stored in SQL database. If this is the case LegacyUserCredentialsTable needs to be added to the method for the users to keep using their set secrets. New SQL users or existing users recreating their secrets will be handled correctly. See more details from TOTP Authentication Method and OTP Printout authentication method - SSO
IDS-3062 - CIBA adapter has been updated to include client_id in aud claim and id_token expiration time. Configuration information can be found from Installing and configuring Swedish BankID
IDS-3009 - TOTP method can now be used without additional schema changes when using AD LDS as Ubilogin Directory together with external SQL directory
Corrections
IDS-1511 - SSO Password reset: old tokens not invalidated. There are built-in features that can be used to mitigate

IDS-60: Disabled users cannot log in to applications with accounts that are linked by User Driven Federation.
When a user authenticates with a federated identity and a matching local account is returned by a FederationManager implementation (i.e. CIDFederationManager or UbiloginFederationTable), the local account status is now verified and the access is denied if the status is not valid.
The workaround fix Preventing disabled users from logging in with user driven federation as described in the page User driven federation is not needed anymore.
IDS-1014: SSO management doesn't disclose the client_secret for OAuth2 application agents
When uploading a client metadata to an OAuth 2.0 application agent using the SSO Management Console, if the metadata contains a
client_secret, theclient_secretis now removed before storing the metadata in the agent configuration in Ubilogin Directory.Prior to 8.3, the
client_secretwas not removed, but stored as is in the agent configuration in Ubilogin Directory.
Furthermore, even if the
client_secrethas already been stored in the agent configuration, as may be the case for agents that have already been activated prior to SSO 8.3, theclient_secretwill now not be shown in the SSO Management Console nor in the SSO Management API.Prior to 8.3, the
client_secret, if set in the client metadata, was shown in SSO Management Console.
IDS-1052: OTP lists for UbiloginDirectory users created from SSO Management Console are not invalid randomly
IDS-945: Execute flag is set for the bash scripts in the Linux version
IDS-723: The SMTP message that is sent by SMTP OTP method sets the Date header as specified in RFC 822

Ubisecure SSO 8.2.25
Improvements for Finnish MobileID (Mobile Certificate / Mobiilivarmenne) Authentication Method
IDS-578: Configurable status request delay.
The delays between the transaction request and the initial status request, as well as the delay between consecutive status requests after the first one, are configurable. The configuration parameters are
initialStatusRequestDelayandconsecutiveStatusRequestDelay. Refer also to the method configuration guide.
IDS-658: Separate error message when authentication times out.
There is a new error message
LOGIN_EXPIREDthat is shown whenever authentication timeout occurs. The timeout is set in theae.timeoutconfiguration parameter. The possible error messages are listed under ETSI MSS Mobile PKI Unregistered Screen in Login Screens.
Corrections
IDS-589: Chrome: Forms submitted using POST to SSO's browser endpoints don't work.
SSO 8.2.19 and 8.2.24 had the issue with Chrome browser, that Forms submitted using POST method to SSO's browser endpoint return 403 Forbidden HTTP status. This caused problems for example with SAML 2.0 login sequence with Ubisecure SAML SP module, because it uses SAML HTTP-POST binding by default, which is based on send a form using POST. That issue is now fixed.
Ubisecure SSO 8.2.24
Improvements and Corrections for Finnish Mobile ID (Mobile Certificate / Mobiilivarmenne) Authentication Method
IDS-89: Configurable length of Event Identifier
Length of the event identifier used for matching the authentication event in the mobile device and the browser can now be configured to be 4 to 8 digits long. This is done by setting the new configuration parameter
eventIdLength, which is also described in the method configuration documentation.
IDS-555: Show the error message for missing or invalid NoSpamCode
When NoSpamCode has been asked from a user, but the NoSpamCode the user has given is invalid or missing, error message is now shown to the user to indicate what went wrong.
IDS-556: NoSpamCode field being visible or not is preserved when error message is shown
NoSpamCode field is hidden in login screen with error message, if the field was also hidden before the error. Conversely, the field is shown, if it was also shown before the error.
IDS-582: Correct text in the label for the phone number is shown in the wait screen
The wait screen (the screen where the Event Identifier is shown) shows now correct text
MPKI_UNREGISTERED_MOBILENUMBERin the label for the phone number.
Other Changes
IDS-464: Mobile Connect / OpenID Connect: SSO decrypts an encrypted Mobile Connect login_hint when passed to OpenID Connect Authentication Provider
SSO passes login_hint to an Open ID Connect Authentication Provider as a generic unencrypted OpenID Connect login_hint also, if the login_hint originates from a Mobile Connect Authentication Request that contains an encrypted login_hint.
Ubisecure SSO 8.2.19
Improvements and Corrections
IAM-2304: OpenID Connect authentication method
OpenID Connect authentication providers can now be used as authentication methods in SSO. For more information, please see the documentation in OpenID Connect authentication method - SSO.
IAM-1038: OpenID Connect: Support for configuration of essential JSON Web Algorithms in encryption and signing
Along with the previously supported RS256 digital signing algorithm, we have added support for HS256, in which the signing key is derived from client_secret value. For encryption, there are also options for algorithms in key management and content encryption.
Complete list of supported algorithms for the various endpoints can be found in the OpenID Connect provider metadata (see documentation for OAuth 2.0 and OpenID Connect metadata - SSO).
Reference: https://tools.ietf.org/html/rfc7518
IAM-2156: OpenID Connect: Configurable idtoken encryption and signing
Added support for enabling encryption for idtokens, which can be configured by setting id_token_encrypted_response_alg and id_token_encrypted_response_enc configuration parameters in the client metadata. The digital signing algorithm used for idtokens can respectively be configured by setting id_token_signed_response_alg (by default it is "RS256").
Complete list of supported values is provided in the id_token_encryption_alg_values_supported, id_token_encryption_enc_values_supported and id_token_signing_alg_values_supported attributes in the OpenID Connect provider metadata (see documentation for OAuth 2.0 and OpenID Connect metadata - SSO).
IAM-2157: OpenID Connect: Configurable userinfo response encryption and signing
Added support for enabling encryption for userinfo endpoint responses, which can be configured by setting userinfo_encrypted_response_alg and userinfo_encrypted_response_enc configuration parameters in the client metadata. The digital signing algorithm used for userinfo response can respectively be configured by setting userinfo_signed_response_alg (by default no signature is added to userinfo response).
Complete list of supported values is provided in the userinfo_encryption_alg_values_supported, userinfo_encryption_enc_values_supported and userinfo_signing_alg_values_supported attributes in the OpenID Connect provider metadata (see documentation for OAuth 2.0 and OpenID Connect metadata - SSO).
IAM-2303: OpenID Connect client integrations: JSON Web Token (JWT) Profile for Client Authentication
Added support for JWT based methods client_secret_jwt and private_key_jwt for client authencation. The method to be used by the client integration can be configured by setting token_endpoint_auth_method and token_endpoint_auth_signing_alg configuration parameters in the client metadata.
Complete list of supported values is provided in the token_endpoint_auth_methods_supported attribute in the OpenID Connect provider metadata (see documentation for OAuth 2.0 and OpenID Connect metadata - SSO).
