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, version(s) 5.4 and prior, contain(s) an Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') vulnerability. A low privileged attacker with local access could potentially exploit this vulnerability, leading to Command execution and Elevation of 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

Dell Unity storage systems versions 5.4 and prior contain an OS command injection vulnerability where improper input validation allows a low-privileged local attacker to inject malicious OS commands, potentially achieving arbitrary command execution and privilege escalation to higher permission levels.

MitigationApply the vendor-supplied patch or upgrade to a Dell Unity version beyond 5.4. Since this is a storage array, follow Dell's recommended update procedure with appropriate backup and downtime planning.

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 Unity Unisphere web interface, navigate to Settings > Support > System Information, or run 'uvmcli -c system -show' from the service CLI to retrieve the installed OE version
    Affected if The displayed version is 5.4.x or lower, or any version below 5.5.0.0.5.259
  2. Confirm version is in vulnerable range
    Compare the retrieved version number against the affected range: versions strictly less than 5.5.0.0.5.259 are vulnerable
    Affected if Version is < 5.5.0.0.5.259 (for example, 5.4.0.0, 5.3.x, 5.2.x, etc.)
  3. Verify local access exists on the system
    Check for any local user accounts, service accounts, or SSH access that provide low-privileged login to the Unity system. Review user accounts via Unisphere (Settings > Access > Management) or via 'user -list' in the service CLI
    Affected if Local user accounts or service accounts with shell/CLI access are present on the system
  4. Identify if input-serving modules are accessible
    The vulnerability involves improper input validation in modules that accept user-supplied data for OS command processing. Audit any custom scripts, diagnostic tools, or management interfaces that accept external input. Check for user-created scripts in /home/nas/ or /svc/scripts/ directories via service CLI
    Affected if Custom scripts, diagnostic tools, or input-accepting interfaces are configured and accessible to low-privileged local users

A system is affected if it runs Dell Unity Operating Environment version 5.4 or any version below 5.5.0.0.5.259 AND has local user accounts or accessible input-handling modules that could be exploited for command injection.

Upgrade available Upgrade to 5.5.0.0.5.259 or later
Fixed in 5.5.0.0.5.259
Interim mitigation

Apply the vendor-supplied patch or upgrade to a Dell Unity version beyond 5.4. Since this is a storage array, follow Dell's recommended update procedure with appropriate backup and downtime planning.

Recommended fix Moderate confidence

5.5.0.0.5.259 or later

  1. Upgrade the Dell Unity Operating Environment to version 5.5.0.0.5.259 or later
  2. Verify the upgrade was successful by checking the system version after installation
  3. Confirm the vulnerability is remediated by verifying the installed version meets the minimum requirement
