The bundled JAAS login modules leak whether a username exists and compare credentials in a non-constant-time manner. A remote unauthenticated attacker can enumerate valid accounts and may infer credential material through timing analysis. Users are recommended to upgrade to version 10.3.0 or 11.0.0-M2, which fix the issue.

The stateful session bean passivation mechanism derives the on-disk file name from a client-supplied identifier without validating it. A remote attacker with access to the remote EJB service can cause session state to be read from or written to files outside the passivation directory. Users are recommended to upgrade to version 10.3.0 or 11.0.0-M2, which fix the issue.

Stateful session bean identifiers are not generated from a cryptographically secure random source. A remote attacker with access to the EJB remote endpoint who holds one valid identifier can derive those of other clients' sessions and invoke methods on their beans, exposing or modifying other users' session state. Users are recommended to upgrade to version 10.3.0 or 11.0.0-M2, which fix the issue.

When JAX-WS or JAX-RS endpoints are published by the embedded OpenEJB HTTP server rather than Tomcat, some configured authentication methods are silently ignored and the endpoint is published without authentication. A remote unauthenticated attacker can invoke the exposed operations without credentials. Only deployments that use the embedded HTTP server and rely on such an authentication method are affected. Users are recommended to block network access to the embedded HTTP server from untrusted clients, or to migrate to the Tomcat based TomEE distributions.

When using the default configuration and no users are defined in the default user database, the software silently creates an administrative user with a well-known password during startup. A remote attacker can utilize these credentials to authenticate to web applications using the default realm, potentially gaining access to any authenticated user privileges or the administrative role.

The optional request routing feature forwards requests to their configured destination without applying the security constraints of that destination or the protection of the web application's private directories. If a route copies client-controlled parts of the request path into its destination, a remote attacker can reach protected resources or read application configuration and class files. Only installations with such a routing configuration are affected. Users are recommended to upgrade to version 10.3.0 or 11.0.0-M2, which fix the issue.

The embedded server generates HTTP session identifiers with a non-cryptographic random number generator by default. A remote attacker who observes a session identifier can predict the identifiers issued to other users and hijack their sessions, if the application relies on HTTP sessions for authentication. Users are recommended to upgrade to version 10.3.0 or 11.0.0-M2, which fix the issue.

The Jakarta Security OpenID Connect authentication mechanism generates the state and nonce values with a non-cryptographic random number generator and insufficient entropy. A remote attacker who predicts these values can forge an authentication callback that logs a victim into the attacker's account, and the replay protection for ID tokens is weakened. Users are recommended to upgrade to version 10.3.0 or 11.0.0-M2, which fix the issue.

The LDAP identity store accepts an empty password as valid when the directory server allows unauthenticated binds, a configuration present by default in some directory servers. This allows a remote attacker to authenticate as any existing user without providing a password.

The Jakarta Security LDAP identity store does not neutralize special characters in the caller name before using it in directory queries. A remote unauthenticated attacker can alter the queries to enumerate accounts, infer directory attribute values, or influence which directory entry the login is validated against. Only applications using the LDAP identity store are affected. Users are recommended to upgrade to version 10.3.0 or 11.0.0-M2, which fix the issue.

Internal system EJBs (Enterprise JavaBeans) used for remote deployment and configuration fail to enforce administrative role checks when the server operates with the default profile. A remote unauthenticated attacker with access to the remote EJB endpoint can deploy arbitrary applications and execute code. This issue specifically affects installations where system applications and a remote EJB endpoint are enabled.

When running on JDK 21 or later, the software skips EJB method authorization checks. This allows callers to invoke EJB methods without the configured access restrictions being enforced.

The embedded OpenEJB HTTP server does not limit the size of incoming request bodies or of multipart requests, and does not remove the temporary files it creates for multipart parts. A remote unauthenticated attacker can cause excessive memory or disk usage, leading to denial of service. Deployments using the Tomcat connectors are not affected. Users are recommended to block network access to the embedded HTTP server from untrusted clients, or to migrate to the Tomcat based TomEE distributions.

The remote EJB client does not verify that the hostname of the server it connects to matches the server's TLS certificate. An attacker able to intercept network traffic between an EJB client and server can impersonate the server and read or modify the traffic, including credentials and invocation data. Users are recommended to upgrade to version 10.3.0 or 11.0.0-M2, which fix the issue.

The embedded Derby network service ignores its configured bind address and listens on all network interfaces. When the service is enabled, a remote attacker with network access can connect to the database server and read or modify data. Users are recommended to upgrade to version 10.3.0 or 11.0.0-M2, which fix the issue.

The EJBd remote protocol returns datasource connection details, including database credentials, to remote clients that look up a datasource. A remote client able to reach the EJBd endpoint can obtain the database credentials and connect to the database directly. Users are recommended to upgrade to version 10.3.0 or 11.0.0-M2, which fix the issue.

When Hessian remoting endpoints are served by the embedded HTTP server, configured authentication and transport security requirements are silently ignored. A remote unauthenticated attacker can invoke the exposed EJB methods without credentials or over an unencrypted connection. Only deployments that use the embedded HTTP server rather than Tomcat and rely on these settings are affected. Users are recommended to block network access to Hessian endpoints from untrusted clients, or to migrate to another remoting protocol.

When an EJB is exposed over the optional Hessian protocol inside an existing web application, some configured authentication and transport security settings are silently not enforced. A remote unauthenticated attacker can invoke the exposed EJB methods. Only deployments using the Hessian module with such settings are affected. Users are recommended to block network access to Hessian endpoints from untrusted clients, or to migrate to another remoting protocol.

When Hessian remoting is configured with BASIC authentication, the authentication check is not applied to Hessian endpoints of applications deployed under a non-root context path. A remote unauthenticated attacker can invoke the exposed EJB methods without credentials. Users are recommended to block network access to Hessian endpoints from untrusted clients, or to migrate to another remoting protocol.

The embedded OpenEJB HTTP server dispatches some requests to REST endpoints configured for HTTP Basic authentication without verifying credentials. A remote unauthenticated attacker can invoke protected resources, bypassing authentication. Only deployments that use the embedded HTTP server with Basic authentication are affected. Users are recommended to block network access to the embedded HTTP server from untrusted clients, or to migrate to the Tomcat based TomEE distributions.
