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
VMware Workspace One Access, Access Connector, Identity Manager, and Identity Manager Connector address have a command injection vulnerability.

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

Command injection vulnerability in VMware Workspace One Access, Access Connector, Identity Manager, and Identity Manager Connector allowing execution of arbitrary commands on the affected systems.

MitigationApply vendor-supplied patches or updates for affected VMware products; restrict network access to administrative interfaces.

Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

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 installed VMware identity product
    Check installed software or running services for VMware Identity Manager, Workspace One Access, or related components. Look for service names like 'vmware-identity-manager', 'horizon-workspace', or similar.
    Affected if The product matches one of: VMware Identity Manager, VMware Identity Manager Connector, VMware Workspace One Access, VMware Cloud Foundation, or VMware vRealize Suite Lifecycle Manager
  2. Check product version number
    Use the product's administrative console, service management interface, or check installed package/version information. For Identity Manager, typically found in /opt/vmware/horizon/workspace/ or via the admin UI at /SAAS/admin. For Cloud Foundation and vRealize LCM, check the VMware product UI or API.
    Affected if Version equals 3.3.1, 3.3.2, or 3.3.3 (Identity Manager/Connector); equals 20.01 or 20.10 (Workspace One Access); equals 4.0 or 4.0.1 (Cloud Foundation); or is between 8.0 and 8.2 inclusive (vRealize Suite Lifecycle Manager)
  3. Verify administrative interface is accessible
    Confirm the administrative web interface (typically port 443/https) is reachable. The vulnerability is exploitable through the configurator or admin endpoints. Check network exposure and firewall rules.
    Affected if The administrative interface is exposed to network traffic, particularly untrusted networks
  4. Check for evidence of compromise
    Review system logs, particularly authentication and command execution logs, for unexpected commands, shells spawned, or suspicious admin actions around the configurator endpoint.
    Affected if Unexpected commands appear in logs, especially those originating from admin API endpoints

Your environment is affected if any of these VMware products are running the specific versions listed and the administrative interface is network-accessible.

Generated from the published advisory. Verify against your own configuration.

Paste your version and any relevant configuration and it will be compared against the affected criteria above. Do not include secrets or credentials.

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.

Upgrade available Upgrade to a release after 8.2
Interim mitigation

Apply vendor-supplied patches or updates for affected VMware products; restrict network access to administrative interfaces.

Recommended fix High confidence

Identity Manager/Connector: 3.3.4+ | One Access: 20.02 or 20.10.0.1+ | Cloud Foundation: 4.0.2+ | vRSLCM: 8.3+

  1. 1. Identify the exact VMware product and version running in your environment from: Identity Manager (3.3.1-3.3.3), Identity Manager Connector (3.3.1-3.3.3), One Access (20.01, 20.10), Cloud Foundation (4.0, 4.0.1), or Vrealize Suite Lifecycle Manager (8.0-8.2)
  2. 2. For Identity Manager 3.3.x: upgrade to version 3.3.4 or later
  3. 3. For Identity Manager Connector 3.3.x: upgrade to version 3.3.4 or later
  4. 4. For One Access 20.01: apply patch OR upgrade to 20.02 or later
  5. 5. For One Access 20.10: apply patch OR upgrade to 20.10.0.1 or later
  6. 6. For Cloud Foundation 4.0/4.0.1: upgrade to 4.0.2 or later
  7. 7. For Vrealize Suite Lifecycle Manager 8.0-8.2: upgrade to 8.3 or later
  8. 8. After upgrade, verify the OAuth2 ACS endpoint is no longer exposed to unauthenticated network access
Caveat Upgrade may require downtime; test in non-production first; review release notes for dependency changes
