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
EMC Isilon OneFS 7.1 before 7.1.1.8, 7.2.0 before 7.2.0.4, and 7.2.1 before 7.2.1.1 allows remote authenticated administrators to bypass a SmartLock root-login restriction by creating a root account and establishing a login session.

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

EMC Isilon OneFS contains a privilege escalation vulnerability where authenticated administrators can bypass SmartLock root-login restrictions by creating a root account and establishing a login session, effectively gaining unauthorized root access to the system.

MitigationUpgrade EMC Isilon OneFS to version 7.1.1.8, 7.2.0.4, 7.2.1.1 or later to resolve the vulnerability.

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 OneFS version
    Run the OneFS version command (such as 'isi version' or 'isi_get_version') to retrieve the installed OneFS version number
    Affected if The installed version is 7.1.0.0 through 7.1.0.5, 7.1.1.0 through 7.1.1.7, 7.2.0.0, 7.2.0.2, or 7.2.1.0 (versions at or below 7.1.1.7, or specifically equal to any listed affected version)
  2. Verify SmartLock status
    Check if the SmartLock feature is enabled on the system by examining the OneFS configuration (typically via 'isi smb' or authentication settings)
    Affected if SmartLock is enabled and the OneFS version falls within the affected range listed above
  3. Review administrative user accounts
    List all local user accounts with root-level privileges using the OneFS authentication administration tools (such as 'isi auth' commands)
    Affected if There are root accounts present other than the expected system default root account, or if unauthorized administrator-created accounts exist with root access
  4. Audit recent account creation events
    Review OneFS audit logs or system logs for recent creation of root-level accounts, focusing on actions performed by authenticated administrators
    Affected if Root accounts were created after the initial system setup, indicating potential exploitation of this vulnerability

You are affected if your OneFS version is within the affected list (versions <= 7.1.1.7, or exactly 7.1.0.0-7.1.0.5, 7.1.1.0-7.1.1.1, 7.2.0.0, 7.2.0.2, or 7.2.1.0) AND SmartLock is enabled and you discover unexpected root accounts or unauthorized administrative privilege escalation.

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