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 NetWeaver Guided Procedures (Administration Workset), versions - 7.10, 7.20, 7.30, 7.31, 7.40, 7.50, does not perform necessary authorization checks for an authenticated user, resulting in escalation of privileges. The impact of missing authorization could result to abuse of functionality restricted to a particular user group, and could allow unauthorized users to read, modify or delete restricted 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.

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. Verify SAP NetWeaver Guided Procedures is installed
    In the SAP system, navigate to System > Status or use transaction code SM37 to check installed software components. Look for component 'Guided Procedures' or 'EP-GUIDEDPROC' in the installed software catalog.
    Affected if The Guided Procedures component is listed as installed in the SAP system
  2. Check the installed Guided Procedures version
    Use SAP transaction code SAINT (SAP Installation Tool) or SMICM (Internet Communication Manager) to view installed product versions. Locate the Guided Procedures version number and compare it exactly to 7.10, 7.20, 7.30, 7.31, 7.40, or 7.50.
    Affected if The installed version matches exactly 7.10, 7.20, 7.30, 7.31, 7.40, or 7.50
  3. Verify if Administration Workset is configured
    In SAP NetWeaver Administrator (NWA), navigate to Operations > Systems > System Landscape > Components. Look for the Administration Workset component under Guided Procedures configuration, or use transaction code NWA > Configuration > Guided Procedures Administration.
    Affected if The Administration Workset is deployed and active in the Guided Procedures environment
  4. Review user authorization role assignments
    Use transaction code PFCG (Role Maintenance) to examine roles assigned to users who have access to Guided Procedures. Check whether standard user roles have been granted elevated administrative privileges that should be restricted to specific user groups.
    Affected if Authenticated users without elevated group membership can access administrative functions through Guided Procedures

A system is affected if SAP NetWeaver Guided Procedures versions 7.10 through 7.50 is installed with the Administration Workset enabled and users can access restricted functionality beyond their assigned authorization group.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Apply the relevant SAP security patch for CVE-2021-33671 and review/strengthen authorization role assignments in the affected SAP system.

Recommended fix Moderate confidence
  1. 1. Access the SAP Support Portal at support.sap.com/patches using your S-user ID
  2. 2. Search for SAP Security Note related to CVE-2021-33671 (typically identified by an SAP Note number)
  3. 3. Download and implement the security patch as instructed in the SAP Note
  4. 4. Apply the patch following SAP's standard patch deployment procedures
  5. 5. Verify the authorization controls are properly enforced after patch application
  6. 6. Test that users can only access functionality permitted by their assigned roles
Caveat SAP Security Notes typically do not introduce breaking changes but should be tested in a non-production system first
