CVE-2022-50980
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 unauthenticated adjacent attacker could potentially disrupt operations by switching between multiple configuration presets via CAN.
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 confidenceAn unauthenticated attacker with physical proximity to a Controller Area Network (CAN) bus can send messages to switch between configuration presets, potentially causing operational disruption in affected vehicle or industrial control systems.

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.
-
Identify CAN bus usageReview system architecture documentation or network diagrams to determine if the system implements Controller Area Network (CAN) bus for inter-device communication, particularly for configuration or control functions.Affected if The system uses CAN bus for communication and no additional authentication layer exists on CAN messages.
-
Locate CAN bus interfacesInspect the system for CAN bus controllers, transceivers, or diagnostic ports (e.g., OBD-II connector in vehicles, DB9/CAN connector in industrial equipment). Use commands like 'ip link show' or check /sys/class/net on Linux systems for can0, can1 interfaces.Affected if CAN bus interfaces are present and active without message authentication enforcement.
-
Check for message authenticationExamine CAN bus configuration files, firmware settings, or intrusion detection system logs to determine whether incoming CAN messages are validated for source authenticity before processing. Look for settings related to CAN ID filtering, message signing, or MAC-based verification.Affected if No cryptographic authentication or message validation is enforced on CAN bus traffic before configuration preset changes are processed.
-
Identify configuration preset mechanismReview system documentation or reverse-engineer CAN bus message definitions to determine if specific CAN message IDs or data patterns correspond to configuration preset switching commands.Affected if Configuration presets can be triggered by unauthenticated CAN bus messages without requiring privileged access or additional verification.
-
Test CAN bus message acceptanceWith appropriate hardware (CAN adapter) and in an isolated test environment, observe whether arbitrary CAN messages with preset-change identifiers are accepted and applied by the controller without challenge or rejection.Affected if The controller processes and executes preset-change commands from the CAN bus without verifying sender authorization.
A system is affected if it uses CAN bus for configuration control and processes preset-change messages without verifying that they originate from authorized sources, allowing any adjacent attacker to disrupt operations.

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 message authentication and authorization checks on the CAN bus to validate that configuration preset changes originate from authorized sources before applying them.
