CVE-2017-9829
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 · unedited'/cgi-bin/admin/downloadMedias.cgi' of the web service in most of the VIVOTEK Network Cameras is vulnerable, which allows remote attackers to read any file on the camera's Linux filesystem via a crafted HTTP request containing ".." sequences. This vulnerability is already verified on VIVOTEK Network Camera IB8369/FD8164/FD816BA; most others have similar firmware that may be affected.
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 confidenceA path traversal vulnerability exists in the /cgi-bin/admin/downloadMedias.cgi CGI script on VIVOTEK network camera web interfaces. The script fails to properly sanitize path traversal sequences ('..'), allowing remote unauthenticated attackers to read arbitrary files from the device's Linux filesystem by crafting HTTP requests containing '../' sequences in the request parameters.

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 modelAccess the camera's web interface or use network scanning to determine if the device is a VIVOTEK Network Camera model Ib8369, Fd8164, or Fd816ba. Check the HTTP Server header or the login page for model identification.Affected if The device is one of these three VIVOTEK camera models.
-
Check the installed firmware versionLog into the camera web interface and navigate to the firmware or system information page, or query the camera's API for version information. Look for the exact firmware string such as 'ib8369-vvtk-0102a', 'fd8164-_vvtk-0200b', or 'fd816ba-vvtk-010101'.Affected if The firmware version matches exactly one of the three affected versions listed.
-
Confirm the CGI script is presentSend an HTTP GET request to http://<camera-ip>/cgi-bin/admin/downloadMedias.cgi and verify the endpoint responds (even if with an error). Use a tool like curl or a browser to test.Affected if The endpoint returns any HTTP response, indicating the script exists and is accessible.
-
Verify network exposure to untrusted sourcesReview firewall rules, NAT configurations, or ACLs to determine whether the camera's HTTP/HTTPS ports (80/443) are accessible from outside the trusted internal network or from the internet.Affected if Port 80 or 443 on the camera is reachable from untrusted networks or the internet.
-
Inspect access logs for path traversal attemptsReview the camera's HTTP access logs or any upstream proxy/firewall logs for requests to /cgi-bin/admin/downloadMedias.cgi containing '../' sequences in query parameters.Affected if Log entries show requests with '../' patterns targeting this CGI endpoint.
A user is affected if they operate a VIVOTEK Ib8369, Fd8164, or Fd816ba camera on the specific affected firmware versions, with the downloadMedias.cgi endpoint exposed to network attackers.

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 from VIVOTEK; if patches are unavailable, isolate affected devices on restricted network segments and block external access to CGI endpoints via firewall rules.
