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
An issue in TeraByte Unlimited Image for Windows v.3.64.0.0 and before and fixed in v.4.0.0.0 allows a local attacker to escalate privileges via the TBOFLHelper64.sys and TBOFLHelper.sys component.

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

A local privilege escalation vulnerability exists in TeraByte Unlimited Image for Windows versions 3.64.0.0 and prior. The kernel-mode drivers TBOFLHelper64.sys and TBOFLHelper.sys contain a flaw allowing a local attacker to elevate privileges, likely by exploiting improper access control or insecure handle handling in these drivers to execute code at SYSTEM privilege level.

MitigationUpgrade to TeraByte Unlimited Image for Windows version 4.0.0.0 or later. If immediate upgrading is not feasible, restrict user access to the affected machine and monitor for any unauthorized use of the vulnerable drivers.

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. Verify TeraByte Unlimited Image for Windows is installed
    Check the system for the product installation. Common locations: C:\Program Files\TeraByte Unlimited\Image for Windows or C:\Program Files (x86)\TeraByte Unlimited\Image for Windows. Look for the program in Add/Remove Programs (appwiz.cpl).
    Affected if The software is present on the system
  2. Determine the installed product version
    Locate the Image for Windows version. Check the program's main executable (tifw.exe) or version info. In the installation folder, right-click the .exe, select Properties, and view the Details tab for Version. Alternatively, check Add/Remove Programs for the installed version.
    Affected if The installed version is 3.64.0.0 or prior
  3. Locate the vulnerable kernel drivers
    Search for TBOFLHelper64.sys and TBOFLHelper.sys on the system. Typical locations: C:\Windows\System32\drivers\ or within the Image for Windows installation directory. Use File Explorer search or run: dir /s C:\TBOFLHelper*.sys
    Affected if Either TBOFLHelper64.sys or TBOFLHelper.sys is present on the system
  4. Verify driver loading status
    Check if the drivers are currently loaded in memory. Open Command Prompt as Administrator and run: sc query TBOFLHelper (or check the driver name in services). Also check Device Manager for the drivers under System devices.
    Affected if The vulnerable drivers are present and loaded/active on the system

The system is affected if TeraByte Unlimited Image for Windows version 3.64.0.0 or prior is installed AND the vulnerable drivers (TBOFLHelper64.sys or TBOFLHelper.sys) are present on the system.
