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 SmartFabric OS10 Software, version(s) 10.5.6.x, 10.5.5.x, 10.5.4.x, 10.5.3.x, contain(s) an Improper Neutralization of Special Elements used in a Command ('Command Injection') vulnerability. A low privileged attacker with local access could potentially exploit this vulnerability, leading to Code execution.

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 Dell SmartFabric OS10 allows a low-privileged local attacker to execute arbitrary code through improper neutralization of special elements in system commands. The attacker with local access (physical or console) can inject malicious commands due to insufficient input sanitization in the affected software versions.

MitigationApply Dell-supplied patches or upgrade to a fixed version of OS10 software; restrict physical and console access to the switch to trusted, authorized personnel only; audit existing user accounts and follow least-privilege principles.

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. Check installed OS10 version
    Access the switch console or CLI and run the command 'show version' to display the installed Dell SmartFabric OS10 software version
    Affected if Version is 10.5.4.0 through 10.5.4.12, 10.5.5.0 through 10.5.5.11, or 10.5.6.0 through 10.5.6.5 (any version in the ranges >=10.5.4.0/<10.5.4.13, >=10.5.5.0/<10.5.5.12, or >=10.5.6.0/<10.5.6.6)
  2. Verify physical or console access exposure
    Determine whether the switch hardware is located in a physically secured location or if console/USB ports could be accessed by untrusted individuals
    Affected if Physical access or console connectivity to the switch is available to low-privileged or untrusted users

The environment is affected if the installed OS10 version falls within any of the three vulnerable ranges AND the switch is accessible via physical or console connection by potential attackers

Fixed in 10.5.4.1310.5.5.1210.5.6.6
Interim mitigation

Apply Dell-supplied patches or upgrade to a fixed version of OS10 software; restrict physical and console access to the switch to trusted, authorized personnel only; audit existing user accounts and follow least-privilege principles.

Recommended fix High confidence

10.5.4.13 (for 10.5.4.x branch), 10.5.5.12 (for 10.5.5.x branch), or 10.5.6.6 (for 10.5.6.x branch) - or latest available in respective branch

  1. 1. Identify the current Smartfabric OS10 version by running 'show version' or 'show system information' in the OS10 CLI
  2. 2. Determine which version branch (10.5.4.x, 10.5.5.x, or 10.5.6.x) the current installation is on
  3. 3. For version 10.5.4.x: upgrade to version 10.5.4.13 or later
  4. 4. For version 10.5.5.x: upgrade to version 10.5.5.12 or later
  5. 5. For version 10.5.6.x: upgrade to version 10.5.6.6 or later
  6. 6. Download the appropriate Dell Smartfabric OS10 update bundle from Dell's support portal (support.dell.com)
  7. 7. Upload the firmware to the switch using 'upload firmware <url>' or via USB/management interface
  8. 8. Install the firmware using 'install firmware' command
Caveat Firmware upgrades may cause brief network disruption; ensure proper change management and have rollback plan; some configuration changes may be required between major version jumps
