CVE-2017-5238
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 bounds checking, several input configuration fields for the Eview EV-07S GPS Tracker will overflow data stored in one variable to another, overwriting the data of another field.
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 contains a buffer overflow vulnerability in multiple input configuration fields due to missing bounds checking. When data is entered into these fields, the lack of proper length validation allows input to overflow from one variable's memory allocation into an adjacent variable, corrupting or overwriting the data stored in that neighboring field.

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 modelCheck the device label, packaging, or administrative interface for the exact model number (Eview EV-07S GPS Tracker or Eviewgps Ev 07s)Affected if Device is confirmed as an Eview EV-07S GPS Tracker (all firmware versions are affected)
-
Locate the device on the networkScan your network for devices responding to typical GPS tracker ports (e.g., HTTP on 80/8080, TCP ports for tracker protocols) and check the manufacturer or web interface bannerAffected if An Eview EV-07S device is found exposed on the network with configuration interfaces accessible
-
Verify configuration interface accessibilityAttempt to access the device web interface or administrative port (typically HTTP on port 80 or 8080) to confirm configuration input fields are reachableAffected if Configuration input fields are accessible without authentication or with default credentials
-
Check for unusual device behaviorReview device logs or observe if configuration fields exhibit unexpected behavior (truncated values, device restarts, or corrupted output in adjacent fields) when entering longer text stringsAffected if Overflow symptoms are observed in configuration fields or adjacent fields show unexpected data corruption
If you have an Eview EV-07S GPS Tracker with accessible configuration interfaces, you are affected since all firmware versions contain the buffer overflow vulnerability in input configuration fields.

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 dataApply any available firmware update from Eview; if no update exists, restrict network access to the device and disable unused configuration interfaces to reduce attack surface.
