CVE-2017-12701
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 · uneditedBMC Medical Luna CPAP Machines released prior to July 1, 2017, contain an improper input validation vulnerability which may allow an authenticated attacker to crash the CPAP's Wi-Fi module resulting in a denial-of-service condition.
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 confidenceImproper input validation in BMC Medical Luna CPAP Machines released prior to July 1, 2017 allows an authenticated attacker to send specially crafted input that crashes the device's Wi-Fi module, resulting in a denial-of-service condition where wireless connectivity is lost.

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 Luna CPAP firmware versionAccess the device settings menu, typically found under 'Info' or 'System' or 'Settings' on the Luna CPAP machine's LCD display. Navigate to the firmware version or software version entry. Alternatively, check the BMC companion app or any connected patient management software for the device firmware information.Affected if The displayed firmware version is earlier than 20170701, or the build/date code precedes July 1, 2017.
-
Verify Wi-Fi connectivity is enabledOn the Luna CPAP device menu, check the wireless/Wi-Fi settings section to confirm Wi-Fi is turned on. This may appear under 'Wireless', 'Wi-Fi', 'Network', or 'Connectivity' settings on the device display.Affected if Wi-Fi is enabled and the firmware version is below 20170701.
-
Confirm Wi-Fi authentication is configuredIn the device Wi-Fi settings, verify that a Wi-Fi network password or authentication method is set for the connection. Ensure the Wi-Fi is not left open or in an unsecured state.Affected if Wi-Fi is enabled with authentication but the firmware is vulnerable (pre-20170701), allowing an authenticated attacker to exploit the input validation flaw.
You are affected if your Luna CPAP device has Wi-Fi enabled and runs firmware dated before July 1, 2017 (version earlier than 20170701).

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 data20170701
Update Luna CPAP firmware to a version released on or after July 1, 2017, or contact BMC Medical for the appropriate patch; ensure Wi-Fi authentication controls are reviewed and strengthened to limit attacker access.
