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
The Vonage Motorola Phone Adapter VT 2142-VD does not encrypt RTP packets, which might allow remote attackers to eavesdrop by sniffing the network and reconstructing the RTP session.

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 Vonage Motorola Phone Adapter VT 2142-VD does not encrypt RTP (Real-time Transport Protocol) audio packets during VoIP calls, allowing attackers on the same network segment to capture traffic via packet sniffing and reconstruct the audio session.

MitigationReplace affected devices with newer VoIP hardware supporting SRTP (Secure RTP) encryption, or implement network segmentation and strict firewall rules to limit exposure to trusted network segments.

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 deployed VoIP device model
    Log into the device admin interface or physically inspect the device label to confirm the model number is Vonage Motorola Phone Adapter VT2142-VD
    Affected if The device model matches VT2142-VD
  2. Verify the firmware version
    Check the device admin page (typically at 192.168.15.1) under the firmware or status section to confirm the running firmware version
    Affected if Any firmware version is running on the VT2142-VD model, as all versions are affected
  3. Capture and inspect RTP traffic on the network segment
    Use a packet sniffer such as Wireshark or tcpdump on the same network segment as the VoIP device. Filter for RTP traffic using the filter 'rtp' and examine whether the payload appears as cleartext audio data
    Affected if RTP packets are visible in cleartext/uneencrypted format in the capture
  4. Check if SRTP encryption is negotiated
    During a VoIP call, capture SIP and SDP signaling to check whether 'RTP/SAVP' (Secure RTP) or 'RTP/AVP' (unencrypted RTP) is advertised in the session description
    Affected if The device advertises or negotiates RTP/AVP rather than RTP/SAVP, indicating unencrypted media
  5. Verify network segment exposure
    Determine if the VoIP device is connected to a shared network segment where other untrusted devices or users have access
    Affected if The device operates on a network segment accessible to untrusted users, increasing exploitation feasibility

If a Vonage Motorola VT2142-VD device is deployed and unencrypted RTP traffic is observable on the network, the environment is affected by this vulnerability.
