CVE-2016-8827
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 · uneditedNVIDIA GeForce Experience 3.x before GFE 3.1.0.52 contains a vulnerability in NVIDIA Web Helper.exe where a local web API endpoint, /VisualOPS/v.1.0./, lacks proper access control and parameter validation, allowing for information disclosure via a directory traversal attack.
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 · high confidenceNVIDIA GeForce Experience 3.x before version 3.1.0.52 contains a directory traversal vulnerability in the NVIDIA Web Helper.exe component. The local web API endpoint /VisualOPS/v.1.0./ lacks proper access control and parameter validation, allowing authenticated local users to traverse directories and access sensitive system files.

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 NVIDIA GeForce Experience is installedOpen Programs and Features (appwiz.cpl) or check for NVIDIA GeForce Experience in the installed programs list. The application is typically installed in C:\Program Files\NVIDIA Corporation\GeForce Experience or C:\Program Files (x86)\NVIDIA Corporation\GeForce Experience.Affected if NVIDIA GeForce Experience appears in the installed programs list
-
Determine the installed versionRight-click on the NVIDIA GeForce Experience entry in Programs and Features and select Properties, then view the Version field. Alternatively, right-click the GeForce Experience executable in the installation folder and select Properties > Details to see the File Version.Affected if The version shown is 3.0.x through 3.1.0.51 (i.e., version is >= 3.0 but < 3.1.0.52)
-
Confirm NVIDIA Web Helper service is runningOpen Task Manager or Services.msc and look for NVIDIA Web Helper.exe in the processes or services list. This component runs as a local web server.Affected if NVIDIA Web Helper.exe process is actively running on the system
-
Check if the vulnerable endpoint respondsUsing a local web browser or curl.exe, navigate to http://localhost:PORT/VisualOPS/v.1.0./ where PORT is the port used by the Web Helper service. The default HTTP port can be identified by running 'netstat -ano | findstr LISTENING' and looking for entries associated with NVIDIA Web Helper.exe.Affected if The endpoint returns an HTTP 200 response and accepts path traversal requests (e.g., /VisualOPS/v.1.0./../../windows/win.ini)
A system is affected if NVIDIA GeForce Experience version 3.0 through 3.1.0.51 is installed AND the NVIDIA Web Helper service is running, allowing unauthenticated local access to the vulnerable /VisualOPS/v.1.0./ endpoint.

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 data3.1.0.52
Upgrade NVIDIA GeForce Experience to version 3.1.0.52 or later, which implements proper access controls and input validation on the affected web API endpoint.
