Release notes

14.8.3 (2023-11-08)

Resolved issues

  • Fixes a bug introduced in v14.8.1 that affects Connect2id server deployments with an SQL database. The bug resulted in repeat duplicate SQL delete queries when purging expired records in the database, causing excessive slowdown of the purge task in SQL tables with many expired records, such as records for subject sessions (issue server/938, sql-store/25).

  • The *.sqlStore.deleteTimer metrics must include SQL delete queries performed as part of purges of expired records (issue sql-store/26).

Dependency changes

  • Updates to com.nimbusds:oauth2-authz-store:24.7.2

  • Updates to com.nimbusds:oidc-session-store:16.7.4

  • Updates to com.nimbusds:infinispan-cachestore-sql:7.1.1

Connect2id server 14.8.2

2023-11-02

This second Connect2id server release for today fixes an issue in v14.8.1 with the Log4j Web 2.21.1 BOM that introduced an erroneous transitive dependency to two Spring artifacts. The erroneous dependency is now removed and we'll make a report upstream.

As always, more information can be found in the release notes below.

Connect2id server 14.8.1

2023-11-02

This maintenance release of the Connect2id server addresses issues related to the SQL database connector, which is now optimised to conserve memory when purging expired entres. An issue slowing down the server startup with Oracle Databases is also fixed. If you have a deployment that uses an SQL database and deals with significant traffic updating to 14.8.1 is recommended.

Updating to 14.8.1 can be skipped if you have a Connect2id server deployment that uses DynamoDB.

Release notes

14.8.1 (2023-11-02)

Resolved issues

  • Updates the expired entry reaper for Connect2id server deployments with an SQL database to conserve memory by employing paged key set seek, in sets of up to 100 SQL records and interleaving the record deletion between the pages. Intended to prevent OOM errors in deployments with a very large number of sessions and other expiring objects (issue server/935).

  • Optimises the dataSource.createTableIfMissing implementation for Oracle Databases when the queried table has a very large number of records, causing Connect2id server startup to pause for times longer than 1 minute at startup. The issue is addressed by switching from LIMIT 0 to LIMIT 1 in the query to obtain the table's column names (issue server/933).

  • The expired entry reaper in Connect2id server deployments with an SQL database must not terminate when an unchecked parse or another exception is thrown when parsing a retrieved SQL record. This may occur in SQL records manipulated outside the Connect2id server APIs. Instead, the exception must be swallowed and an error with the offending SQL record logged. This is now done with an IS0141 log error (issue sql-store/23).

  • Fixes the default value and parsing of the optional sessions form parameter of the /session-store/rest/v2/purge resource (issue session-store/95).

Dependency changes

  • Updates to com.nimbusds:oauth2-authz-store:24.7.1

  • Updates to com.nimbusds:oidc-session-store:16.7.3

  • Upgrades to com.nimbusds:infinispan-cachestore-sql:7.1

  • Updates to Log4j 2.21.1

Connect2id server 14.8 enables client_secret_jwt and private_key_jwt replay prevention

2023-10-20

This Connect2id server release receives the capability to prevent replay of JWTs for the client_secret_jwt and private_key_jwt client authentication methods.

The replay prevention relies on the optional jti (JWT ID), which when included must be a unique string. Without a jti JWTs using a deterministic JWS algorithm, such as HMAC, that expire at the same second cannot be reliably distinguished. For authentication JWTs that have this identifier the Connect2id server will cache its hash until the JWT's exp and use that record to prevent replay. This means that for replay prevention to work an OAuth 2.0 client must includes a unique jti in its authentication JWTs. Clients using the Nimbus OAuth 2.0 SDK always receive these tokens with a random 256-bit jti.

In Connect2id server deployments where caching of jti hashes for every received client_secret_jwt and private_key_jwt is not feasible, this security feature can be disabled. The amount of store required for the jti caching can be regulated by configuring the Connect2id server to reject authentication JWTs with an exp that is too far ahead.

Example configuration to reject authentication JWTs that are more than 60 seconds ahead of the current system time:

op.token.authJWTExpMaxAhead=60

Offending OAuth 2.0 clients will receive a standard invalid_client error and must reduce their exp time to fit the server's policy.

Regardless of this configuration, to prevent accidental or malicious DoS, the Connect2id server will never cache a jti for more that 5 minutes.

This Connect2id server release also updated the available configuration properties for deployments with a PostgreSQL database, which now supports the setting of a database schema (namespace).

Release notes

14.8 (2023-10-20)

Summary

  • Implements configurable replay prevention of "client_secret_jwt" and "private_key_jwt" client authentication JWT assertions based on the optional JWT ID ("jti") claim. The implementation is based on the new expended token registry introduced in Connect2id server 14.0.

  • Updates the PostgreSQL configuration to enable setting of a JDBC "schema" parameter. Intended for Connect2id server deployments that want to use a database schema other than the default "public".

Configuration

  • /WEB-INF/oidcProvider.properties

    • op.token.authJWTPreventReplay -- New optional configuration property. If true replay of "client_secret_jwt" and "private_key_jwt" client assertions will be prevented, by caching the JWT "jti" claim for the duration of the assertion lifetime but no longer than 5 minutes. The default value is true.

    • op.token.authJWTExpMaxAhead -- New optional configuration property. Sets the maximum allowed number of seconds of the expiration time (exp) claim in "client_secret_jwt" and "private_key_jwt" client assertions ahead of the current time. Assertions with longer expiration time will be rejected with an invalid_client error. If zero or negative this check is disabled. When enabled the value must be between 10 and 600 seconds. The default value is -1 (disabled).

  • /WEB-INF/infinispan-*-postgres95.xml

    • dataSource.databaseSchema -- New optional Java system property to set the PostgreSQL schema to use. Corresponds to the HikariCP "schema" configuration property. The default value is empty (implies the default "public" PostgreSQL schema).

Web API

  • /par

    • Requests with "client_secret_jwt" and "private_key_jwt" authentication will be prevented from replaying a used JWT assertion, unless the JWT assertion is missing the optional the JWT ID (jti) claim or the replay prevention is disabled by setting the op.token.authJWTPreventReplay configuration property to false.

  • /token

    • Requests with "client_secret_jwt" and "private_key_jwt" authentication will be prevented from replaying a used JWT assertion, unless the JWT assertion is missing the optional the JWT ID (jti) claim or the replay prevention is disabled by setting the op.token.authJWTPreventReplay configuration property to false.

  • /token/introspect

    • Requests with "client_secret_jwt" and "private_key_jwt" authentication will be prevented from replaying a used JWT assertion, unless the JWT assertion is missing the optional the JWT ID (jti) claim or the replay prevention is disabled by setting the op.token.authJWTPreventReplay configuration property to false.

Resolved issues

  • Updates the authz-session log INFO "OP2101" and "OP2103" messages to include the current issuer URL when issuer aliasing is enabled (issue server/925).

  • Updates the authz-session log DEBUG "OP2130" and WARN "OP2131", "OP2132" messages to include the authorisation session ID (issue server/925).

Dependency changes

  • Upgrades to com.nimbusds:oauth2-oidc-sdk:11.4

  • Upgrades to com.nimbusds:oauth2-authz-store:24.7

  • Updates to com.nimbusds:software-statement-verifier:2.2.6

  • Updates to org.apache.santuario:xmlsec:2.2.6

Connect2id server and CVE-2023-5072

2023-10-16

Our CVE scanner recently returned a DoS vulnerability for the JSON.org dependency org.json:json:20230227.

https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2023-5072

Fortunately this dependency is used in a single, non-critical place, to evaluate JSON paths as part of a configuration check in the optional software statement verifier (SSV) plugin of the Connect2id server.

There is no need to take action, unless all of the following applies:

  1. You have enabled open dynamic client registration:

    op.reg.allowOpenRegistration=true

  2. You have a Connect2id server deployment with an enabled SSV plugin:

    op.ssv.enable=true

  3. The plugin is configured for op.ssv.scopeRules.* that represent JSON Path queries.

Due to that fact that the scope rules check is performed only after a successfully authenticated (JWS validated) software statement, the DoS exploitation risk is minimal.

We have released a patched up SSV plugin that bumps the org.json:json dependency to 20231013.

<dependency>
    <groupId>com.nimbusds</groupId>
    <artifactId>software-statement-verifier</artifactId>
    <version>2.2.6</version>
</dependency>

The patched up SSV plugin will be included in the next Connect2id server release.
