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
Dell Unity, versions prior to 5.4, contains an OS Command Injection Vulnerability in its svc_cifssupport utility. An authenticated attacker could potentially exploit this vulnerability, escaping the restricted shell and execute arbitrary operating system commands with root privileges.

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 · high confidence

OS command injection vulnerability in the svc_cifssupport utility on Dell Unity storage arrays versions prior to 5.4 allows an authenticated attacker to escape the restricted shell environment and execute arbitrary operating system commands with root privileges.

MitigationUpgrade Dell Unity systems to version 5.4 or later, or apply vendor-supplied patches, as this vulnerability cannot be mitigated through configuration changes alone.

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 the Dell Unity system version
    Access the Dell Unity management interface (Unisphere) or use the service CLI to run: 'version' or 'system -version' to retrieve the Operating Environment version number
    Affected if The installed version is lower than 5.4.0.0.5.094 (e.g., 5.3.x, 5.2.x, etc.)
  2. Confirm the svc_cifssupport utility exists
    On the Dell Unity system, check for the presence of the svc_cifssupport binary in the service shell or by listing /service/scripts/ or equivalent service directories
    Affected if The svc_cifssupport utility is present on the system
  3. Verify authentication mechanisms
    Check if local or remote authentication is enabled for the Dell Unity service shell or Unisphere by reviewing user accounts and access controls
    Affected if There are any authenticated user accounts (including service accounts) that can access the system
  4. Check for restricted shell access
    Determine if any user has access to the restricted service shell where svc_cifssupport is executable by reviewing user role assignments
    Affected if Any authenticated user has access to the service shell environment where svc_cifssupport can be invoked

A Dell Unity system is affected if it runs Operating Environment version below 5.4.0.0.5.094 and has the svc_cifssupport utility accessible to authenticated users.

Upgrade available Upgrade to 5.4.0.0.5.094 or later
Fixed in 5.4.0.0.5.094
Interim mitigation

Upgrade Dell Unity systems to version 5.4 or later, or apply vendor-supplied patches, as this vulnerability cannot be mitigated through configuration changes alone.

Recommended fix Moderate confidence

Dell Unity Operating Environment 5.4.0.0.5.094 or later

  1. Verify current Dell Unity Operating Environment version using system management interface or CLI
  2. Download Dell Unity OE version 5.4.0.0.5.094 or later from Dell support portal
  3. Review Dell Unity upgrade documentation for proper upgrade procedure
  4. Execute upgrade following Dell-approved upgrade path, typically via Service UI or upgrade bundle
  5. Verify successful upgrade by confirming new version number post-upgrade
  6. Validate that svc_cifssupport utility behavior is now restricted
