CVE-2019-15065
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 · uneditedA service which is hosted on port 6998 in HiNet GPON firmware < I040GWR190731 allows an attacker to execute a specific command to read arbitrary files. CVSS 3.0 Base score 9.3. CVSS vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:N/A:L).
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 confidenceHiNet GPON fiber optic router firmware versions before I040GWR190731 contain a service listening on port 6998 that suffers from an arbitrary file read vulnerability. An unauthenticated attacker can send a specific command to the service to read any file on the system, likely due to insufficient input validation or path traversal in the file request handler.

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 model and confirm it is a HiNet GPON routerCheck the device label, administrative web interface, or SNMP information to confirm the device is an HiNet GPON fiber optic router model (such as I040GWR series)Affected if The device is not an HiNet GPON router - the vulnerability only affects this specific product line
-
Check the installed firmware versionAccess the router administrative interface or use the command line (telnet/ssh if available) to retrieve the firmware version. Compare it against the affected version i040gwr190731Affected if The firmware version is less than i040gwr190731 (for example, i040gwr190615 or earlier)
-
Verify if port 6998 is open and listeningPerform a port scan against the router from the LAN or WAN interface using 'nmap -p 6998 <router_ip>' or similar network scanning toolAffected if Port 6998 is open and responding - this indicates the vulnerable service is running
-
Test for unauthorized file access (controlled check)Send a crafted request to port 6998 attempting to read a non-sensitive file (such as /etc/passwd or a known configuration file). Note: This is an active test and should only be performed on systems you own or have explicit permission to testAffected if The service returns file contents from arbitrary paths, confirming the path traversal vulnerability is present
The device is affected if it is a HiNet GPON router running firmware version earlier than i040gwr190731 with port 6998 open and accessible, and the service allows reading arbitrary files without authentication.

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 dataUpdate HiNet GPON firmware to version I040GWR190731 or later. If immediate patching is not possible, restrict network access to port 6998 using firewall rules or disable the service if not required.
