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
Huawei FusionSphere OpenStack V100R006C00SPC102(NFV) has a privilege escalation vulnerability. Due to improper privilege restrictions, an attacker with high privilege may obtain the other users' certificates. Successful exploit may cause 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

Huawei FusionSphere OpenStack V100R006C00SPC102 contains a privilege escalation vulnerability caused by improper privilege restrictions. An attacker who already possesses high-level privileges can obtain other users' certificates, which can then be used to impersonate those users and escalate privileges further within the NFV platform.

MitigationApply the vendor-provided patch from Huawei for this specific vulnerability. If no patch is available, review and restrict the privilege assignment logic to ensure proper separation between user certificates and enforce least-privilege access 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. Verify FusionSphere OpenStack version
    Access the FusionSphere OpenStack management interface or run 'VIM' version command to confirm the installed firmware version matches v100r006c00spc102(nfv)
    Affected if The installed version is exactly v100r006c00spc102(nfv)
  2. Identify user certificate storage location
    Locate where user certificates are stored in the FusionSphere OpenStack environment by reviewing the certificate management module or configuration files
    Affected if User certificates are stored in a location accessible to high-privilege users without proper isolation
  3. Examine privilege assignment logic
    Review the privilege assignment configuration files or API to determine how user certificates map to roles and permissions within the NFV platform
    Affected if The privilege logic allows high-privilege users to access or export other users' certificates
  4. Check certificate access controls
    Inspect access control lists or file permissions on the certificate storage to see if high-privilege users can read certificates belonging to other users
    Affected if Certificates for other users are readable by accounts with high-level privileges

A user is affected if running FusionSphere OpenStack v100r006c00spc102(nfv) and high-privilege accounts can access or obtain other users' certificates without proper restrictions.
