CVE-2023-23771
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 · uneditedMotorola MBTS Base Radio accepts hard-coded backdoor password. The Motorola MBTS Base Radio Man Machine Interface (MMI), allowing for service technicians to diagnose and configure the device, accepts a hard-coded backdoor password that cannot be changed or disabled.
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 confidenceThe Motorola MBTS Base Radio Man Machine Interface (MMI) contains a hard-coded backdoor password embedded in the firmware that cannot be changed or disabled by administrators. This provides unauthenticated access to the device's diagnostic and configuration functions.

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 device modelLog into the MMI web interface or check the device physical label to confirm the device is a Motorola MBTS Base Radio. Look for 'MBTS' or 'Base Radio' in the device identification section.Affected if The device is not a Motorola MBTS Base Radio - different models are not affected by this specific CVE.
-
Check firmware versionIn the MMI interface, navigate to the System Status or About page to view the installed firmware version. The version is displayed as 'r05.x2.57' or similar.Affected if The installed firmware version is exactly r05.x2.57 - this is the only affected version listed for this CVE.
-
Verify MMI accessibilityAttempt to access the MMI diagnostic or configuration interface via the web interface or console. The backdoor provides unauthenticated access to these functions.Affected if The MMI diagnostic/configuration interface is accessible without authentication - this confirms the backdoor is present and exploitable.
-
Confirm version matches exactlyCompare the installed firmware version string against the affected version 'r05.x2.57'. Note this is an exact version match (equals), not a range.Affected if The firmware version is precisely r05.x2.57 - versions before or after this specific release are not affected by this CVE.
You are affected if your Motorola MBTS Base Radio is running exactly firmware version r05.x2.57, as this is the only version listed as containing the hardcoded backdoor password.

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 dataNetwork segmentation and physical access controls should be implemented to limit exposure; contact Motorola for firmware patch availability.
