CVE-2007-5792
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 · uneditedThe 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 confidenceThe 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.

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 the deployed VoIP device modelLog into the device admin interface or physically inspect the device label to confirm the model number is Vonage Motorola Phone Adapter VT2142-VDAffected if The device model matches VT2142-VD
-
Verify the firmware versionCheck the device admin page (typically at 192.168.15.1) under the firmware or status section to confirm the running firmware versionAffected if Any firmware version is running on the VT2142-VD model, as all versions are affected
-
Capture and inspect RTP traffic on the network segmentUse 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 dataAffected if RTP packets are visible in cleartext/uneencrypted format in the capture
-
Check if SRTP encryption is negotiatedDuring 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 descriptionAffected if The device advertises or negotiates RTP/AVP rather than RTP/SAVP, indicating unencrypted media
-
Verify network segment exposureDetermine if the VoIP device is connected to a shared network segment where other untrusted devices or users have accessAffected 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.

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 dataReplace 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.
