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
SAP Plant Connectivity - version 15.5 (PCo) or the Production Connector for SAP Digital Manufacturing - version 1.0, do not validate the signature of the JSON Web Token (JWT) in the HTTP request sent from SAP Digital Manufacturing. Therefore, unauthorized callers from the internal network could send service requests to PCo or the Production Connector, which could have an impact on the integrity of the integration with SAP Digital Manufacturing.

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

SAP Plant Connectivity and Production Connector for SAP Digital Manufacturing fail to validate JWT signatures in HTTP requests from SAP Digital Manufacturing. This allows unauthorized internal attackers to forge service requests by crafting malicious JWTs without proper signature verification, compromising the integrity of the integration.

MitigationImplement and enforce JWT signature validation on all incoming requests from SAP Digital Manufacturing, and ensure PCo or Production Connector versions include proper cryptographic verification of token authenticity.

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 installed SAP Digital Manufacturing version
    Locate the version information for SAP Digital Manufacturing in the product's about section, system information, or version registry
    Affected if The installed version is exactly 1.0 (or falls within the affected range if more detail were provided)
  2. Identify installed SAP Plant Connectivity version
    Locate the version information for SAP Plant Connectivity in the product's about section, system information, or version registry
    Affected if The installed version is exactly 15.5 (or falls within the affected range if more detail were provided)
  3. Inspect JWT validation configuration
    Examine the security or integration configuration settings where JWT handling is defined; look for signature verification, token validation, or authentication settings
    Affected if JWT signature validation is disabled, not configured, or set to bypass verification for incoming requests from SAP Digital Manufacturing
  4. Review token validation logs
    Check system or application logs for any entries related to JWT token processing, signature verification, or authentication of requests from SAP Digital Manufacturing
    Affected if Logs show that JWT tokens are being accepted without signature verification or contain errors indicating missing validation logic

You are affected if you run SAP Digital Manufacturing 1.0 or SAP Plant Connectivity 15.5 AND JWT signature validation is not enforced in your integration configuration.

Generated from the published advisory. Verify against your own configuration.

Mitigation

Implement and enforce JWT signature validation on all incoming requests from SAP Digital Manufacturing, and ensure PCo or Production Connector versions include proper cryptographic verification of token authenticity.

Recommended fix Moderate confidence

Apply the SAP Security Note for CVE-2023-2827 or upgrade to the fixed release as specified in the SAP Security Note

  1. Check SAP Security Note for CVE-2023-2827 on the SAP Support Launchpad to obtain the specific patch or correction
  2. Apply the SAP Security Note patch to Plant Connectivity version 15.5 and/or Production Connector for SAP Digital Manufacturing version 1.0
  3. After applying the patch, verify that JWT signature validation is now enforced for HTTP requests
  4. Test the integration between SAP Digital Manufacturing and PCo/Production Connector to confirm the fix works correctly
Caveat Review the SAP Security Note for any configuration changes or potential impacts on existing integrations
