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 within its svc_cbr utility. An authenticated malicious user with local access could potentially exploit this vulnerability, leading to the execution of arbitrary OS commands on the application's underlying OS, with the privileges of the vulnerable application.

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

Dell Unity storage systems prior to version 5.4 contain an OS command injection vulnerability in the svc_cbr utility. An authenticated user with local access can exploit improper input sanitization to inject and execute arbitrary operating system commands with the privileges of the underlying application.

MitigationUpgrade Dell Unity to version 5.4 or later, which contains the vendor patch for this vulnerability. If upgrading is not immediately feasible, restrict local access to trusted, authorized personnel only.

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 Dell Unity Operating Environment version
    Access the Unisphere management interface or use the CLI command 'uemcli -sys version' or check the system information page in Unisphere. The version is displayed as the OE version.
    Affected if The displayed version is earlier than 5.4.0.0.5.094 (e.g., 5.3.x, 5.2.x, etc.)
  2. Confirm svc_cbr utility is present
    On the Dell Unity system CLI, verify the svc_cbr utility exists in the service directory by checking if the binary or script is present (typically under /service or similar paths accessible to authenticated users).
    Affected if The svc_cbr utility is present and executable by authenticated local users.
  3. Verify local access is enabled
    Check if local user authentication is configured on the Unity system. Review user accounts created directly on the appliance via 'user -list' or the local user configuration in Unisphere under Access > Management > Local Users.
    Affected if Local user authentication is enabled and local user accounts exist on the system.

You are affected if your Dell Unity Operating Environment version is earlier than 5.4.0.0.5.094 AND local authenticated users can access the svc_cbr utility.

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 to version 5.4 or later, which contains the vendor patch for this vulnerability. If upgrading is not immediately feasible, restrict local access to trusted, authorized personnel only.

Recommended fix High confidence

Unity Operating Environment 5.4.0.0.5.094 or later

  1. 1. Identify the current Dell Unity Operating Environment version by accessing the Unisphere web interface and navigating to Settings > About, or by running the 'svc_unisphere -version' command via the service CLI.
  2. 2. Confirm the current version is below 5.4.0.0.5.094 to determine if the system is vulnerable.
  3. 3. Schedule a maintenance window for the upgrade, ensuring adequate downtime is allocated.
  4. 4. Back up all critical data and configuration settings following Dell best practices for Unity systems.
  5. 5. Download the Unity OE 5.4.0.0.5.094 (or later stable release) update package from the Dell Support website (support.dell.com) using valid support credentials.
  6. 6. Apply the update through the Unisphere interface: navigate to Settings > Update, select the downloaded package, and initiate the installation.
  7. 7. Alternatively, for CLI-based updates, upload the bundle to the service processor and run 'svc_update -bundle <filename>' command.
  8. 8. After the update completes, verify the new version by checking Settings > About to confirm the system is now running 5.4.0.0.5.094 or later.
