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
An authorization bypass through user-controlled key vulnerability affecting 3DSwym in 3DSwymer on Release 3DEXPERIENCE R2024x allows an authenticated attacker to access some unauthorized data.

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 · moderate confidence

This is an authorization bypass vulnerability in 3DSwym (a collaboration/social component) within 3DSwymer on the 3DEXPERIENCE R2024x release. The vulnerability stems from improper validation of user-controlled keys that an authenticated attacker can manipulate to access data they are not authorized to view, bypassing the intended access control boundaries.

MitigationApply the vendor patch for 3DEXPERIENCE R2024x when available, and conduct access control review across 3DSwym to ensure all data access paths properly validate authorization before returning content.

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. Confirm 3DSwym component is installed
    Locate the 3DSwym application within the 3DEXPERIENCE platform installation directory, typically under the 3DSwymer collaborative apps folder, or verify via the 3DEXPERIENCE platform administration console that the 3DSwym module appears in the list of installed applications.
    Affected if 3DSwym is present and listed as an installed component within the 3DSwymer suite.
  2. Identify the 3DEXPERIENCE platform version
    Check the installed 3DEXPERIENCE platform version through the platform administration tool, About dialog, or by querying the platform version service. Confirm whether the version string indicates R2024x.
    Affected if The platform version is exactly R2024x or falls within the R2024x release family.
  3. Verify 3DSwym web service is accessible
    Confirm the 3DSwym REST API or web interface is accessible by attempting to reach the 3DSwym endpoint (typically under the 3DSwymer context path in the 3DEXPERIENCE web deployment).
    Affected if The 3DSwym web service responds to HTTP requests, indicating the component is active and reachable.
  4. Review 3DSwym access control configuration
    Inspect the 3DSwym access control settings through the 3DEXPERIENCE administration console, specifically examining how user-controlled parameters are validated when accessing collaborative data. Look for any custom or non-standard authorization rules.
    Affected if The access control configuration allows user-supplied keys or parameters to influence data retrieval without proper authorization validation.
  5. Test for authorization bypass via parameter manipulation
    Using an authenticated user account with limited permissions, attempt to access another user's collaborative content by manipulating URL parameters, request headers, or API keys that control data ownership or sharing scope.
    Affected if An authenticated user can successfully access data outside their authorized scope by modifying user-controlled parameters.

A user is affected if they have 3DSwym installed on a 3DEXPERIENCE R2024x platform and the 3DSwym web interface is accessible, as the authorization bypass requires the component to be active and reachable.
