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) 10.5.4.x, 10.5.5.x, 10.5.6.x, 10.6.0.x, contain(s) an Use of Default Password vulnerability. A low privileged attacker with remote access could potentially exploit this vulnerability, leading to Unauthorized access.

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 SmartFabric OS10 Software versions 10.5.4.x through 10.6.0.x contain hardcoded default credentials that allow a low-privileged attacker with network access to authenticate to the fabric management interface and gain unauthorized administrative access.

MitigationChange all default passwords to strong, unique credentials immediately and disable unnecessary remote administrative access according to Dell hardening guidelines.

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. Determine installed OS10 version
    Run 'show version' or 'system show version' from the OS10 CLI to obtain the exact firmware version number
    Affected if The version falls within these ranges: >= 10.5.4.0 and < 10.5.4.14; OR >= 10.5.5.0 and < 10.5.5.13; OR >= 10.5.6.0 and < 10.5.6.8; OR >= 10.6.0.0 and < 10.6.0.2
  2. Verify remote administrative access status
    Run 'show ip ssh' or 'show http server' to check if SSH, HTTP, or HTTPS management interfaces are enabled and configured for remote access
    Affected if Remote management protocols (SSH/HTTP/HTTPS) are enabled and accessible from untrusted networks
  3. Confirm default credentials have been changed
    Review all locally configured user accounts using 'show users accounts' and verify that no factory-default usernames or passwords remain in use. Check for any undocumented admin-level accounts.
    Affected if Any default user account created during initial setup remains unchanged or unknown accounts exist with administrative privileges
  4. Inspect management access logs
    Review authentication logs via 'show logging | include auth' or equivalent to identify any successful logins from unexpected sources or IP addresses
    Affected if Logs show successful administrative logins from IP addresses that are not recognized as legitimate administrator sources

Your environment is affected if the installed OS10 version falls within the specified vulnerable ranges AND remote management access is enabled AND default credentials have not been changed from factory settings.

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

Check your environment

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.

Fixed in 10.5.4.1410.5.5.1310.5.6.8
Interim mitigation

Change all default passwords to strong, unique credentials immediately and disable unnecessary remote administrative access according to Dell hardening guidelines.

Recommended fix High confidence

Upgrade to 10.5.4.14 (if on 10.5.4.x), 10.5.5.13 (if on 10.5.5.x), 10.5.6.8 (if on 10.5.6.x), or 10.6.0.2 (if on 10.6.0.x) - preferably the latest available fixed version in your release train

  1. 1. Identify the current SmartFabric OS10 version by running 'show version' or checking the system banner at login
  2. 2. Based on your current version, plan upgrade to the minimum fixed version: if on 10.5.4.x upgrade to 10.5.4.14; if on 10.5.5.x upgrade to 10.5.5.13; if on 10.5.6.x upgrade to 10.5.6.8; if on 10.6.0.x upgrade to 10.6.0.2
  3. 3. Review Dell SmartFabric OS10 upgrade documentation and release notes for upgrade procedures specific to your deployment
  4. 4. Test the upgrade in a non-production environment first to verify compatibility with your network configuration
  5. 5. Perform a configuration backup before upgrading using 'copy running-config startup-config' or equivalent
  6. 6. Execute the upgrade following Dell's recommended procedures (typically via ONIE or OS10 upgrade image)
  7. 7. After upgrade completes, verify the new version using 'show version'
  8. 8. Change all default credentials immediately after upgrade to unique, strong passwords as a security best practice
Caveat Review Dell release notes for your target version; some features or configurations may behave differently after upgrade - test thoroughly in staging first
