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 · unedited
Motorola MBTS Site Controller accepts hard-coded backdoor password. The Motorola MBTS Site Controller 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 confidence

The Motorola MBTS Site Controller's Man Machine Interface (MMI), used by service technicians for device diagnostics and configuration, contains a hard-coded backdoor password that cannot be changed or disabled by administrators. This provides unauthenticated access to the device's full management functions.

MitigationSince the password cannot be changed or disabled, apply network segmentation to isolate the MMI interface from untrusted networks and implement strict firewall rules to limit access to authorized IP addresses only. Contact Motorola for available firmware updates.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify the device model
    Access the device's web interface, command-line interface, or SNMP banner and look for 'Motorola MBTS Site Controller' or 'MMI' identification strings
    Affected if The device is NOT a Motorola MBTS Site Controller - if different, this CVE does not apply
  2. Check the firmware version
    Access the MMI diagnostic interface via its web UI or CLI and navigate to the firmware version or system information section, or query via SNMP if available
    Affected if The firmware version is NOT exactly r05.32.58 - only this exact version is affected per the advisory
  3. Determine MMI interface accessibility
    Scan network for open ports associated with the MMI interface (typically HTTP/HTTPS on web ports, or check device documentation for MMI service ports). Verify if the interface is reachable from your network segments.
    Affected if The MMI interface is not network-accessible at all (not exposed) - the backdoor cannot be exploited if the interface cannot be reached
  4. Assess network exposure of MMI service
    Review firewall rules, ACLs, and network segmentation around the device. Check if the MMI interface is accessible from untrusted network segments or the internet.
    Affected if The MMI interface is directly exposed to untrusted networks or the internet without restrictive access controls

You are affected if you have a Motorola MBTS Site Controller running exactly firmware r05.32.58 with its MMI interface accessible from your network
