CVE-2018-4014
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 exploitable code execution vulnerability exists in Wi-Fi Command 9999 of the Roav A1 Dashcam running version RoavA1SWV1.9. A specially crafted packet can cause a stack-based buffer overflow, resulting in code execution. An attacker can send a packet to trigger this vulnerability.
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 confidenceA stack-based buffer overflow vulnerability exists in Wi-Fi Command 9999 of the Roav A1 Dashcam firmware (RoavA1SWV1.9). Attackers can send specially crafted packets to overflow a stack-based buffer, achieving arbitrary code execution on the device.

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 the device modelLocate the physical device or check device documentation for the exact model name. Confirm it is a Roav A1 Dashcam or Anker In Roav Dashcam A1.Affected if The device is not a Roav A1 Dashcam model.
-
Check the installed firmware versionAccess the device settings or admin interface to view the firmware version. This is typically found under System Settings, About, or Device Info. The version string should be roava1swv1.9.Affected if The firmware version is exactly roava1swv1.9.
-
Verify Wi-Fi is enabledCheck the device network settings or Wi-Fi configuration. Look for Wi-Fi or wireless connectivity options and confirm the Wi-Fi interface is turned on.Affected if Wi-Fi is enabled and active on the device.
-
Confirm network accessibility of the deviceDetermine if the device is reachable from untrusted networks. Check if the device IP address is exposed to the internet or if it can be accessed from networks outside your local trusted network.Affected if The device is reachable from untrusted or external networks.
You are affected if you have a Roav A1 Dashcam with firmware version roava1swv1.9, Wi-Fi is enabled, and the device is accessible from a network where untrusted attackers can send packets to it.

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 dataApply vendor-supplied firmware patches when available; otherwise, restrict network exposure by disabling unused Wi-Fi functionality or placing the device behind a firewall to prevent unauthenticated attackers from reaching the vulnerable service.
