CVE-2016-9337
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 · uneditedAn issue was discovered in Tesla Motors Model S automobile, all firmware versions before version 7.1 (2.36.31) with web browser functionality enabled. The vehicle's Gateway ECU is susceptible to commands that may allow an attacker to install malicious software allowing the attacker to send messages to the vehicle's CAN bus, a Command Injection.
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 confidenceA command injection vulnerability in the Tesla Model S Gateway ECU allows attackers to inject malicious commands through the web browser functionality. Successful exploitation enables installation of malicious software and allows attackers to send arbitrary messages to the vehicle's CAN bus, potentially giving them control over critical vehicle systems. This affects all firmware versions before 7.1 (2.36.31).

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.
-
Retrieve Gateway ECU firmware versionAccess the vehicle's diagnostic interface or infotainment system settings to identify the current Gateway ECU firmware version. This may require using Tesla's service mode, OBD-II diagnostic tool, or consulting vehicle system information in the main display.Affected if Firmware version is below 7.1 (2.36.31)
-
Confirm web browser is accessibleVerify that the vehicle's built-in web browser functionality is enabled and can be launched from the infotainment system. Check if the browser feature is present and operational.Affected if Web browser functionality is enabled and accessible
-
Cross-reference version against affected rangeCompare the identified Gateway ECU firmware version against the affected range: all versions before 7.1 (2.36.31).Affected if Gateway ECU runs firmware prior to version 7.1 (2.36.31)
A Tesla Model S Gateway ECU is vulnerable if it runs firmware versions before 7.1 (2.36.31) and the web browser feature is enabled, allowing command injection and potential CAN bus manipulation.

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 the vehicle's firmware to version 7.1 (2.36.31) or later to patch the command injection vulnerability. Until the update is applied, consider disabling the web browser functionality if not strictly necessary.
