CVE-2017-5239
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 · uneditedDue to a lack of standard encryption when transmitting sensitive information over the internet to a centralized monitoring service, the Eview EV-07S GPS Tracker discloses personally identifying information, such as GPS data and IMEI numbers, to any man-in-the-middle (MitM) listener.
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 Eview EV-07S GPS Tracker transmits sensitive data including GPS coordinates and IMEI numbers to a centralized monitoring service without encryption. This transmission security failure allows any man-in-the-middle attacker to intercept and collect personally identifiable information (PII).

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 device modelLocate the GPS tracker device and check its physical label, packaging, or documentation for the exact model number. Confirm it is an Eview EV-07S GPS Tracker.Affected if The device is an Eview EV-07S GPS Tracker (any firmware version)
-
Capture outbound network trafficUse a network sniffer or packet capture tool (such as Wireshark or tcpdump) on the network segment where the device communicates. Capture traffic leaving the device to its remote monitoring server.Affected if Traffic is observed being transmitted in plain text (no TLS/SSL encryption) to remote servers on ports like 80, 8080, or other non-encrypted protocols
-
Verify encryption on data transmissionExamine the captured packets for GPS coordinates and IMEI numbers. Check if these sensitive fields are sent in cleartext rather than within an encrypted TLS/SSL tunnel. Look for HTTPS (port 443) with valid certificates versus HTTP (port 80) or raw socket connections.Affected if GPS coordinates and IMEI data are transmitted unencrypted over the network
-
Check for TLS/SSL handshakeDuring packet capture, verify whether a TLS/SSL handshake occurs between the device and the monitoring server. Absence of TLS negotiation indicates unencrypted communication.Affected if No TLS/SSL handshake is observed; data flows directly without encryption protocol
If the Eview EV-07S GPS Tracker transmits GPS coordinates and IMEI numbers to remote servers without TLS/SSL or equivalent encryption, 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 dataImplement network segmentation and VPN tunnels to encrypt traffic from the GPS devices; contact the vendor for a firmware patch that implements TLS/SSL encryption for all data transmissions.
