CVE-2021-22311
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 · uneditedThere is an improper permission assignment vulnerability in Huawei ManageOne product. Due to improper security hardening, the process can run with a higher privilege. Successful exploit could allow certain users to do certain operations with improper permissions. Affected product versions include: ManageOne versions 8.0.0, 8.0.1.
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 confidenceImproper permission assignment vulnerability in Huawei ManageOne where due to inadequate security hardening, certain processes run with elevated privileges. This allows authenticated users to perform operations beyond their intended permission level through the improperly privileged process.

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 checksWork through these to decide whether this CVE applies to you.
-
Identify ManageOne installation versionAccess the ManageOne administration console or check the installation directory for version information. Typically found in /opt/ManageOne/version or through the management interface under 'System Information' or 'About'.Affected if The installed version is exactly 8.0.0 or exactly 8.0.1
-
Review process privilege configurationsExamine running ManageOne service processes using system commands such as 'ps aux' or 'tasklist' to identify processes running with elevated or root-level privileges. Compare against documented expected privilege levels for each service.Affected if Any ManageOne service process runs with privileges exceeding what is required for its documented function, or runs as root/superuser when not documented as necessary
-
Verify user role permission assignmentsAccess the ManageOne user management or RBAC (Role-Based Access Control) configuration panel. Review role definitions and verify that authenticated users can only access operations matching their assigned roles.Affected if Users with standard or limited roles can perform administrative or elevated operations through certain service processes
-
Audit process-to-user mappingCheck the service account configurations and process ownership for ManageOne components. Look for services executing under privileged accounts (such as root, administrator, or svc_admin) versus dedicated service accounts with limited permissions.Affected if ManageOne services execute under high-privilege accounts when lower-privilege accounts could be used
A user is affected if their ManageOne installation is version 8.0.0 or 8.0.1 AND certain processes run with elevated privileges beyond what the principle of least privilege would require.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply vendor-supplied security patches for ManageOne 8.0.0/8.0.1 and review process privilege configurations to ensure adherence to principle of least privilege.
