CVE-2018-17931
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 · uneditedIf an attacker has physical access to the VGo Robot (Versions 3.0.3.52164 and 3.0.3.53662. Prior versions may also be affected) they may be able to alter scripts, which may allow code execution with root privileges.
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 confidenceThis vulnerability in VGo Robot allows an attacker with physical access to modify scripts, achieving code execution with root privileges. This suggests inadequate access controls on script files or the script execution environment, allowing unprivileged physical access to alter what should be protected application logic.

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 installed firmware versionDetermine the current Vecna Vgo Firmware version installed on the robot using system diagnostics or firmware retrieval methods.Affected if The firmware version is <= 3.0.3.52164 or exactly 3.0.3.53662
-
Locate script storage directoriesIdentify where the robot stores its executable scripts by reviewing the application file system or configuration.Affected if Scripts are stored in accessible locations on the device
-
Verify script file permissionsExamine the access control settings on script files to determine if write access is restricted to privileged users only.Affected if Script files are writable by unprivileged users or unauthenticated actors
-
Assess physical access exposureDetermine whether physical access to the robot provides the ability to modify or replace script files without requiring authentication.Affected if Physical access allows modification of scripts without authentication or special tools
The environment is affected if the firmware version falls within the vulnerable range AND script files can be modified by an attacker with physical access but without root 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 dataImplement proper access controls on the robot's script storage and execution mechanisms. Restrict physical access to script modification capabilities, and consider script integrity verification (e.g., digital signing) to prevent unauthorized alterations.
