Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
BEA WebLogic Server and WebLogic Express 6.1, 7.0, and 8.1, when using Remote Method Invocation (RMI) over Internet Inter-ORB Protocol (IIOP), does not properly handle when multiple logins for different users coming from the same client, which could cause an "unexpected user identity" to be used in an RMI call.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

BEA WebLogic Server and WebLogic Express 6.1 through 8.1 contain an identity confusion vulnerability when using RMI over IIOP. The server fails to properly maintain separate user identities when multiple logins occur from the same client, causing an unexpected (potentially privilege-escalated) user identity to be used in subsequent RMI calls.

MitigationIf RMI over IIOP is not required, disable the IIOP protocol in WebLogic. Otherwise, apply vendor patches or upgrade to a supported WebLogic version. Implement proper session isolation and authentication handling for RMI calls.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify WebLogic version
    Check the installed BEA WebLogic Server or WebLogic Express version by inspecting the registry, startup scripts, or the BEA home directory structure. Look for version files in the BEA installation directory or check the product version via the WebLogic Administration Console.
    Affected if The installed version is 6.1, 7.0, 7.0.0.1, or 8.1 (any of the listed affected versions).
  2. Confirm IIOP protocol is enabled
    Inspect the WebLogic domain configuration files (config.xml) for the IIOP service settings. Check the Administration Console under Services > IIOP or examine the config.xml file for <iiop-enabled> or similar IIOP-related configuration elements.
    Affected if IIOP protocol is explicitly enabled in the WebLogic domain configuration.
  3. Verify RMI over IIOP is in use
    Examine the Java client applications or server-side code to determine if RMI calls are configured to use the IIOP protocol. Look for RMI registry references using the IIOP protocol (typically using 'iiop://' URLs or Context.PROVIDER_URL with IIOP).
    Affected if RMI clients are configured to communicate via IIOP instead of T3 or other WebLogic-native protocols.
  4. Check for shared client session handling
    Review application code to determine if multiple user logins can occur from the same client JVM or connection context. Examine session management and identity propagation logic in RMI calls.
    Affected if The application allows or expects multiple distinct user logins from a single client process where identity could be confused.

A user is affected if they run any of the affected versions (6.1, 7.0, 7.0.0.1, or 8.1) AND have IIOP enabled with RMI over IIOP in use, particularly when the application handles multiple logins from the same client.
