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
RICOH Interactive Whiteboard D2200 V1.1 to V2.2, D5500 V1.1 to V2.2, D5510 V1.1 to V2.2, the display versions with RICOH Interactive Whiteboard Controller Type1 V1.1 to V2.2 attached (D5520, D6500, D6510, D7500, D8400), and the display versions with RICOH Interactive Whiteboard Controller Type2 V3.0 to V3.1.10137.0 attached (D5520, D6510, D7500, D8400) uses hard-coded credentials, which may allow an attacker on the same network segments to login to the administrators settings screen and change the configuration.

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 RICOH Interactive Whiteboard devices (multiple models and versions) contain hard-coded credentials embedded in the firmware that cannot be changed by administrators. An attacker with network adjacency to the device can use these credentials to bypass authentication and gain administrative access to the device settings panel, allowing configuration changes.

MitigationIf available, apply vendor firmware updates to remove hardcoded credentials. Otherwise, implement network segmentation to restrict access to these devices to only authorized personnel, and contact vendor for patch availability.

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 Ricoh Interactive Whiteboard model
    Check the device label, web interface, or documentation for the model number (D2200, D5500, D5510, D5520, D6500, D6510, D7500, or D8400)
    Affected if Model is one of the eight affected models listed in the CVE
  2. Determine the installed firmware version
    Access the device web settings panel (typically via browser at the device IP) and navigate to the system information or maintenance section to view the firmware version
    Affected if Unable to retrieve firmware version or device is unresponsive
  3. Compare firmware version against affected ranges
    Match your firmware version to these ranges: D2200/D5500/D5510/D6500: 1.1-2.2 affected; D5520/D6510/D7500/D8400: 1.1-2.2 OR 3.0-3.1.10137.0 affected
    Affected if Firmware version falls within any of the listed vulnerable ranges
  4. Verify network accessibility to the admin login
    Attempt to reach the device web interface from a networked system using ping or HTTP/HTTPS to the device IP address
    Affected if Device is reachable over the network and responds on web service ports

If the device is a Ricoh Interactive Whiteboard model D2200, D5500, D5510, D5520, D6500, D6510, D7500, or D8400 with firmware version matching the affected ranges (1.1-2.2, or for D5520/D6510/D7500/D8400 also 3.0-3.1.10137.0), and the admin web interface is network-accessible, then the environment is affected by this hard-coded credential vulnerability.
