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 checksWork through these to decide whether this CVE applies to you.
-
Check if Dell Update Package Framework is installedLook for Dell DUP Framework installation directories (typically under Program Files or Program Files x86) or check Windows Registry under HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall for entries containing 'Dell Update Package' or 'DellUpdate'. You can also check for running processes related to Dell update services.Affected if Dell Update Package Framework is present on the system
-
Identify the installed DUP Framework versionCheck the version of the installed Dell Update Package executable or DLL. Common locations include the installation directory (often C:\Program Files\Dell\UpdatePackage\ or similar). Right-click the main executable, select Properties, and view the Details tab for version information. Alternatively, query the Windows Registry for the DisplayVersion value under the Dell DUP uninstall key.Affected if The version displayed cannot be determined or is not visible
-
Compare installed version against affected rangeThe affected versions are 23.12.00 through 24.12.00 (specifically >= 23.12.00 and < 25.02.00). If your installed version is 23.12.00, 23.12.01, 24.x.x, or any version up to but not including 25.02.00, the system falls within the vulnerable range.Affected if Installed version is 23.12.00 or higher but lower than 25.02.00
-
Check if DUP Framework service or scheduled task is activeOpen Services.msc and look for Dell Update Package related services. Also check Task Scheduler under Dell or UpdatePackage tasks. The vulnerability requires the DUP Framework to be running or scheduled to run, allowing a low-privileged user to trigger the privilege escalation.Affected if A Dell Update Package service or scheduled task is enabled and running on the system
If Dell Update Package Framework is installed with a version between 23.12.00 and 24.12.00 (inclusive) and the DUP service or scheduled task is active, the system is vulnerable to local privilege escalation.

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.
dbcve · scoped25.02.00
Apply the vendor-provided patch or update to a version beyond 24.12.00 when available. Until then, restrict local user permissions and monitor for unauthorized privilege escalation attempts on affected systems.
Version 25.02.00 or later of Dell Update Package (DUP) Framework
- 1. Identify the current version of Dell Update Package (DUP) Framework installed on the system
- 2. Navigate to www.dell.com and locate the Dell Update Package Framework download page
- 3. Download version 25.02.00 or later from Dell's official support site
- 4. Verify the checksum of the downloaded package matches Dell's published checksum
- 5. Apply the update following Dell's standard update installation procedures
- 6. Verify the updated version is correctly installed post-upgrade
