CVE-2019-11417
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 · uneditedsystem.cgi on TRENDnet TV-IP110WN cameras has a buffer overflow caused by an inadequate source-length check before a strcpy operation in the respondAsp function. Attackers can exploit the vulnerability by using the languse parameter with a long string. This affects 1.2.2 build 28, 64, 65, and 68.
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 confidenceBuffer overflow in system.cgi on TRENDnet TV-IP110WN cameras allows remote code execution via the languse parameter. The respondAsp function uses strcpy without validating input length, enabling attackers to overflow a fixed-size buffer by submitting an overly long string.

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 device modelAccess the camera's web interface or check the device label/metadata to confirm the model is TRENDnet TV-IP110WNAffected if Model is TRENDnet TV-IP110WN
-
Check firmware versionLog into the camera's web admin panel and navigate to the System or Status section to view the firmware version, or query the device via SNMP or manufacturer utilityAffected if Firmware version is 1.2.2.28, 1.2.2.64, 1.2.2.65, or 1.2.2.68
-
Verify web interface accessibilityAttempt to access http://[device-ip]/system.cgi or confirm port 80/443 is open and responding on the cameraAffected if The device web interface is reachable from a network segment where attackers could send requests
-
Test languse parameter exposureSend an HTTP GET request to the device with an overly long string in the languse parameter, such as: GET /system.cgi?languse=[200+ characters]Affected if The device accepts the request without rejecting overly long input, indicating the strcpy vulnerability is present
You are affected if you have a TRENDnet TV-IP110WN camera running firmware version 1.2.2.28, 1.2.2.64, 1.2.2.65, or 1.2.2.68, and the system.cgi interface is accessible from your network.

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 update if available; otherwise, isolate device behind firewall or VPN to limit exposure, as no user-applicable patch exists for end-of-life hardware.
