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
FusionSphere OpenStack V100R006C00 has an improper authorization vulnerability. Due to improper authorization, an attacker with low privilege may exploit this vulnerability to obtain the operation authority of some specific directory, causing privilege escalation.

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

FusionSphere OpenStack V100R006C00 contains an improper authorization vulnerability where low-privilege authenticated users can obtain operation authority over specific directories, enabling privilege escalation to higher system privileges.

MitigationApply vendor-provided patches for FusionSphere OpenStack V100R006C00 and review directory permission configurations to enforce proper authorization controls.

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 FusionSphere OpenStack version
    Run system query or check /opt/fusionsphere/VERSION (or vendor-specific version file) to confirm installed version is exactly V100R006C00
    Affected if Installed version equals v100r006c00
  2. Verify low-privilege user existence
    Check for any non-admin user accounts configured in the FusionSphere OpenStack identity service (Keystone)
    Affected if Low-privilege users exist in the system
  3. Inspect directory permission configurations
    Review directory permissions under the FusionSphere installation path, particularly any directories writable by non-admin users
    Affected if Low-privilege users have write or operation authority over system directories they should not access
  4. Check for unauthorized privilege escalation paths
    Examine sudo configurations, file ownership, and ACL settings on directories referenced in the authorization model
    Affected if Directories permit operation authority for users lacking proper privileges

Environment is affected if running FusionSphere OpenStack exactly version V100R006C00 with low-privilege users having improper directory operation permissions that enable escalation.
