CVE-2016-1876
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 · uneditedThe backend service process in Lenovo Solution Center (aka LSC) before 3.3.0002 allows local users to gain SYSTEM privileges via unspecified vectors.
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 confidenceLenovo Solution Center versions before 3.3.0002 contain a local privilege escalation vulnerability in its backend service process. Unauthenticated local users can exploit unspecified vectors to gain SYSTEM-level privileges, effectively obtaining full administrative control over the affected Windows 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.
-
Verify Lenovo Solution Center is installedOpen Programs and Features (appwiz.cpl) or check for the presence of Lenovo Solution Center in the Start Menu. Also check the installation directory typically at C:\Program Files\Lenovo\Lenovo Solution Center or C:\Program Files (x86)\Lenovo\Lenovo Solution Center.Affected if Lenovo Solution Center is present on the system
-
Find installed version numberRight-click the Lenovo Solution Center executable (usually LSClient.exe or similar in the installation folder), select Properties, and check the File Version tab. Alternatively, check the Windows Registry under HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\{ProductCode} for DisplayVersion, or use PowerShell: Get-WmiObject -Class Win32_Product | Where-Object {$_.Name -like '*Lenovo Solution Center*'} | Select-Object Name, VersionAffected if Version is 3.3.0001 or lower
-
Identify backend serviceOpen Services (services.msc) and look for Lenovo Solution Center related services. The vulnerable service is the backend process that runs with elevated privileges. Check the service properties to confirm it runs as Local System or a privileged account.Affected if A Lenovo Solution Center service exists and runs with elevated privileges (Local System account)
-
Confirm version is within affected rangeCompare the retrieved version against the vulnerable range: any version 3.3.0001 or earlier is affected. Version 3.3.0002 and later are not vulnerable.Affected if Installed version is 3.3.0001 or any earlier version number
A user is affected if Lenovo Solution Center version 3.3.0001 or earlier is installed and the backend service runs with SYSTEM-level privileges.

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 dataUpgrade Lenovo Solution Center to version 3.3.0002 or later to remediate this vulnerability. Organizations should also ensure least-privilege principles to limit local user access on systems where the software is installed.
