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
During authorization checks in SAP Human Capital Management for SAP S/4HANA, the system returns specific messages. Due to this, an authenticated user with low privileges could guess and enumerate the content shown, beyond their authorized scope. This leads to disclosure of sensitive information causing a high impact on confidentiality, while integrity and availability are unaffected.

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

SAP HCM for S/4HANA returns specific verbose messages during authorization checks that leak information about sensitive data. An authenticated low-privilege user can enumerate and discover content beyond their authorized scope by analyzing these messages, leading to confidentiality breach.

MitigationConfigure SAP to return generic error messages during authorization failures rather than specific messages that reveal system state or data existence. Apply relevant SAP security notes.

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 HCM product version
    Use SAP transaction codes (such as SM37, SAINT, or SPAM) or check system information to determine the exact version of the Sap Human Capital Management or sap_hrrxx component installed in your system
    Affected if The installed version matches one of the following: s4hcmrxx_100, s4hcmrxx_101, s4hcmrxx_102, sap_hrrxx_600, sap_hrrxx_604, or sap_hrrxx_608
  2. Verify verbose error message configuration
    Check the SAP system profile parameters and security settings related to error message verbosity, typically found in transaction code SU01, SPAD, or system profile settings. Look for settings that control whether authorization failure messages return specific versus generic text
    Affected if System is configured to return specific or detailed error messages rather than generic authorization failure messages
  3. Test authorization error message content
    As a low-privilege authenticated user, attempt to access data or functions outside your authorized scope and capture the exact error message returned. Compare the message content against what a generic authorization failure should return
    Affected if Error messages explicitly indicate whether the requested data or object exists (for example, by differentiating between 'no access' versus 'object not found'), revealing sensitive system state information
  4. Check for information enumeration patterns
    Submit multiple authorization requests for different sensitive objects or records and analyze whether the variation in error messages allows enumeration of what data exists within the system beyond the user's authorized scope
    Affected if Distinct error message patterns allow a low-privilege user to discover the existence of sensitive data they should not be able to see
  5. Review SAP security notes implementation status
    Check if the relevant SAP security notes for this vulnerability have been applied by reviewing the installed support packages or using transaction code SNOTE to verify patch status
    Affected if The specific security notes addressing verbose authorization messages for this CVE have not been applied

Your system is affected if it runs any of the listed SAP HCM versions AND returns specific error messages during authorization failures that reveal whether sensitive data or objects exist, rather than generic messages that hide such information.
