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
PowerSYSTEM Center feature for device project groups allows an authenticated user with limited permissions to perform an unauthorized deletion of project groups.

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

PowerSYSTEM Center has a broken access control vulnerability in its device project groups feature. An authenticated user with limited or standard permissions can delete project groups they should not have authorization to delete, indicating missing or insufficient authorization checks on the deletion operation.

MitigationImplement proper role-based access control (RBAC) checks before executing project group deletions to verify the authenticated user has sufficient permissions for the specific resource being deleted.

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 PowerSYSTEM Center version
    Locate the installed PowerSYSTEM Center version through the product's about dialog, help menu, or system information page typically accessible via the web interface or client application
    Affected if The installed version falls within the affected version range and the device project groups feature is in use
  2. Confirm device project groups feature existence
    Navigate to the device management or project organization section of the PowerSYSTEM Center interface and verify if project groups functionality is present and accessible
    Affected if Project groups feature is enabled and available in the environment
  3. Review user role assignments
    Access the user management or role-based access control configuration panel to identify users assigned limited or standard permission roles
    Affected if Users with limited or standard permissions exist in the system who have any access to project group management
  4. Inspect project group deletion authorization controls
    Examine the access control configuration, permissions matrix, or security settings related to project group operations. Check if role-based permissions explicitly control delete operations on project groups
    Affected if No explicit authorization check or insufficient permission validation is configured for project group deletion, or the delete permission is granted to limited/standard roles
  5. Test or verify deletion authorization for restricted users
    Using an account with limited or standard permissions, attempt to access and delete a project group that was created by a different user or belongs to a higher-privilege role. Observe if the deletion is allowed without proper authorization
    Affected if A limited or standard permission user can successfully delete project groups they did not create or should not have authorization to delete

Your environment is affected if the installed PowerSYSTEM Center version is within the affected range and limited or standard permission users can delete project groups they should not have authorization to access.
