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 Enterprise Financial Services, versions 6.05, 6.06, 6.16, 6.17, 6.18, 8.0 (in business function EAFS_BCA_BUSOPR_2) does not perform necessary authorization checks for an authenticated user, resulting in escalation of privileges.

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 Enterprise Financial Services versions 6.05 through 8.0 contains a broken access control vulnerability in the EAFS_BCA_BUSOPR_2 business function. The application fails to perform proper authorization checks for authenticated users, allowing a user with standard privileges to perform privileged operations and escalate their access rights within the financial services module.

MitigationApply SAP Security Note 2630244 (or subsequent relevant patch) to address the missing authorization checks. Until patched, restrict user role assignments to the EAFS_BCA_BUSOPR_2 business function and monitor for unauthorized privilege escalation attempts.

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 Enterprise Financial Services version
    Execute SAP transaction SM37 or use SAPMMC to view installed software components. Navigate to System > Status > Component Information to find the EFS version.
    Affected if The version matches 6.05, 6.06, 6.16, 6.17, 6.18, or 8.0 from the affected products list.
  2. Verify EAFS_BCA_BUSOPR_2 business function status
    Execute SAP transaction SFW5 (Business Functions) and search for EAFS_BCA_BUSOPR_2. Check the Active status column for this business function.
    Affected if The business function EAFS_BCA_BUSOPR_2 is set to Active in SFW5.
  3. Review user role assignments for EAFS_BCA_BUSOPR_2
    Execute SAP transaction PFCG to view role menus. Search for roles containing EAFS_BCA_BUSOPR_2 or financial services transaction codes. Check User tab to list assigned users.
    Affected if Users with standard (non-privileged) roles have access to this business function.
  4. Audit financial services transaction usage logs
    Execute SAP transaction SE16 or use SAP Audit Log (transaction RSURSYSLOG). Search for financial services module transactions (e.g., FAGLF03, F-02) accessed by users outside expected privileged groups.
    Affected if Standard users are executing privileged financial services transactions they should not have access to.
  5. Check for unauthorized privilege modifications
    Execute SAP transaction SUIM (User Information System). Navigate to Users by Complex Selection and filter for recent role changes or authorization profile modifications. Compare against documented approval records.
    Affected if Standard users have recently gained elevated roles or authorization profiles without proper approval.

You are affected if your SAP Enterprise Financial Services version is between 6.05 and 8.0 AND the EAFS_BCA_BUSOPR_2 business function is enabled with standard users having access to it.
