CVE-2019-6168
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 · uneditedA vulnerability reported in Lenovo Service Bridge before version 4.1.0.1 could allow remote code execution.
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 Service Bridge versions prior to 4.1.0.1 contain a vulnerability that could allow remote code execution. The specific vulnerability type and attack vector are not detailed in the available description, but the critical CVSS score of 9.8 indicates the potential for complete system compromise without authentication.

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 Lenovo Service Bridge is installedSearch for Lenovo Service Bridge in the Windows registry under HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall or HKCU\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall, or check Add/Remove ProgramsAffected if Lenovo Service Bridge appears in the list of installed programs
-
Find the installed version of Lenovo Service BridgeExamine the version field in the registry uninstall entry for Lenovo Service Bridge, or right-click the Service Bridge executable in its installation folder and select Properties to view the File VersionAffected if Version information cannot be located or the software is found but version is not displayed
-
Compare installed version against 4.1.0.1If a version number is found, compare it numerically to 4.1.0.1 - any version with a lower major, minor, or build number is below the fixed versionAffected if Installed version is earlier than 4.1.0.1 (for example, 4.0.x, 3.x, or any version where the first three number groups are less than 4.1.0)
-
Determine if the software is currently runningOpen Task Manager and look for Lenovo Service Bridge processes, or check running services with service name containing 'Lenovo' or 'Service Bridge'Affected if Lenovo Service Bridge process is actively running on the system
A system is affected if Lenovo Service Bridge is installed with any version prior to 4.1.0.1, as this creates the condition for the remote code execution vulnerability to be exploitable.

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 · scoped4.1.0.1
Upgrade Lenovo Service Bridge to version 4.1.0.1 or later to remediate this vulnerability. Given the RCE capability at critical severity, also conduct forensic investigation to determine if any affected systems may have been compromised.
