CVE-2017-15647
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 · uneditedOn FiberHome routers, Directory Traversal exists in /cgi-bin/webproc via the getpage parameter in conjunction with a crafted var:page value.
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 confidenceDirectory traversal vulnerability in FiberHome routers allows remote attackers to access arbitrary files on the filesystem via the /cgi-bin/webproc endpoint using '../' sequences in the getpage parameter combined with a crafted var:page value.

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.
-
Verify FiberHome router web interface is accessibleAttempt to reach the router's IP at /cgi-bin/webproc endpoint using HTTP GET requestAffected if The webproc endpoint responds with any HTTP status code other than connection timeout or error
-
Confirm remote access to web management is enabledCheck if the router's web interface is reachable from untrusted network interfaces (not just localhost or LAN)Affected if The web interface is accessible from outside the trusted local network
-
Test directory traversal vulnerability in getpage parameterSend HTTP request to /cgi-bin/webproc with getpage parameter containing '../' sequences (e.g., ../../../etc/passwd) and var:page parameter set to a crafted valueAffected if The response returns content from files outside the expected web directory, indicating successful path traversal
-
Verify ability to read sensitive filesAttempt to read known system files such as /etc/passwd or /etc/shadow using the directory traversal pattern in the getpage parameterAffected if The router returns actual file contents from the filesystem, confirming the vulnerability is exploitable
The user is affected if the FiberHome router's /cgi-bin/webproc endpoint is accessible remotely and permits directory traversal to read arbitrary filesystem files using '../' sequences in the getpage parameter.

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 vendor firmware updates when available; meanwhile, restrict network access to the router's web management interface to trusted IP addresses or disable remote administration entirely.
