CVE-2025-12048
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 · uneditedAn arbitrary file upload vulnerability was reported in the Lenovo Scanner Pro client during an internal security assessment that could allow remote code execution or unauthorized control of the affected system.

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.
-
Identify if Lenovo Scanner Pro is installedCheck for Lenovo Scanner Pro in installed programs (Windows: Control Panel > Programs and Features, or PowerShell: Get-ItemProperty HKLM:\Software\Microsoft\Windows\CurrentVersion\Uninstall\* | Where-Object {$_.DisplayName -like '*Scanner*Pro*'})Affected if Lenovo Scanner Pro is found on the system
-
Determine the installed versionOpen Lenovo Scanner Pro, go to Help > About, or check the version in the application's executable properties (right-click the .exe file > Properties > Details)Affected if A version of Lenovo Scanner Pro is installed (compare to affected version range if known)
-
Locate the file upload componentExamine the application directory for upload-related modules, DLLs, or configuration files related to scanning/importing documentsAffected if File upload functionality exists within the application
-
Check upload directory permissions and locationFind the default upload/scan import directory in application settings or configuration files; verify if it is located in a web-accessible or executable pathAffected if Uploaded files are stored in a directory that permits execution or is web-exposed
-
Inspect upload functionality access controlsReview application settings, configuration files, or network traffic to determine if the file upload feature requires authentication or is accessible to unauthenticated usersAffected if File upload endpoint is exposed without proper authentication or access restrictions
A user is affected if Lenovo Scanner Pro is installed and its file upload feature is accessible without sufficient validation or is configured to store files in executable locations.

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.
From vendor dataRestrict file upload functionality to only allow safe file types, implement strict server-side validation, store uploaded files in non-executable directories, and apply proper access controls to prevent execution of uploaded content.
