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
Due to improper validation of certificate in SAP Cloud Connector - version 2.0, attacker can impersonate the genuine servers to interact with SCC breaking the mutual authentication. Hence, the attacker can intercept the request to view/modify sensitive information. There is no impact on the availability of the system.

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 Cloud Connector version 2.0 contains improper certificate validation that breaks mutual TLS authentication. This allows an attacker to perform man-in-the-middle attacks, impersonate legitimate servers, and intercept/view/modify sensitive data in transit.

MitigationEnsure proper certificate chain validation and hostname verification is enforced in SAP Cloud Connector. Update to a patched version if available and verify mutual authentication is functioning correctly.

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 Cloud Connector version
    Check the version of SAP Cloud Connector installed in your environment. This can typically be done via the admin UI, command line tools, or by inspecting the installation directory for version information.
    Affected if The installed version is exactly 2.0 (version 2.0, not higher or lower)
  2. Verify if mutual TLS authentication is configured
    Check whether mutual TLS (mTLS) is enabled in your SAP Cloud Connector configuration. Inspect the SSL/TLS settings in the administration interface or configuration files.
    Affected if Mutual TLS is configured and the certificate validation vulnerability exists in version 2.0
  3. Examine certificate validation settings
    Review the SSL/TLS and certificate validation configuration in SAP Cloud Connector. Look for settings related to certificate chain validation and hostname verification.
    Affected if Certificate validation is not properly enforced or has been intentionally disabled in the configuration
  4. Review backend connection configurations
    Inspect the backend system connections defined in SAP Cloud Connector. Check whether SSL/TLS is required for connections to back-end systems and how certificates are handled.
    Affected if Connections to back-end systems do not enforce proper certificate validation

Your environment is affected if SAP Cloud Connector version 2.0 is installed and mutual TLS authentication is used, due to the improper certificate validation vulnerability in this specific version.

Mitigation

Ensure proper certificate chain validation and hostname verification is enforced in SAP Cloud Connector. Update to a patched version if available and verify mutual authentication is functioning correctly.

Recommended fix Moderate confidence

SAP Cloud Connector version > 2.0 (specific version available via SAP Security Note)

  1. Check the current SAP Cloud Connector version by accessing the administration UI or using the command line tool
  2. Review SAP Security Note for CVE-2024-25642 on the SAP Support Portal (support.sap.com) to obtain the specific patch or version information
  3. If a new version is available, download the latest SAP Cloud Connector from the SAP Software Download Center
  4. Backup the current Cloud Connector configuration and data before upgrading
  5. Stop the Cloud Connector service
  6. Install the new version following SAP's installation documentation
  7. Verify the certificate validation fix is applied by reviewing the release notes or security note
  8. Start the Cloud Connector service and verify proper functionality
Caveat Review SAP Cloud Connector release notes for any configuration or compatibility changes between versions before upgrading
