CVE-2019-6166
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 cross-site request forgery.
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 are vulnerable to cross-site request forgery (CSRF). This allows an attacker to trick an authenticated user into unknowingly submitting malicious requests to the application, potentially performing unauthorized actions on behalf of the user.
Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

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 installedOpen Windows Control Panel and go to Programs and Features, or right-click the Start button and select Apps and Features. Look for Lenovo Service Bridge in the installed programs list.Affected if Lenovo Service Bridge appears in the installed programs list
-
Determine the installed version numberIn Programs and Features, locate Lenovo Service Bridge and note the version shown in the column, or right-click the application executable (typically in Program Files or Program Files x86 under a Lenovo folder) and select Properties to view the Details tab for version information.Affected if Version information is displayed in the programs list or file properties
-
Compare version to vulnerable rangeCompare the installed version to 4.1.0.1 - any version prior to 4.1.0.1 is within the vulnerable range.Affected if Installed version is lower than 4.1.0.1 (for example, 4.0.x, 3.x, or earlier)
-
Verify if application is actively usedSince this is a CSRF vulnerability that requires an authenticated user session, check whether the user actually uses Lenovo Service Bridge to log in to Lenovo services.Affected if The user authenticates to Lenovo Service Bridge to access Lenovo support services
User is affected if Lenovo Service Bridge version is installed and that version is earlier than 4.1.0.1 and the user authenticates to the application.
