CVE-2018-6413
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 · uneditedThere is a buffer overflow in the Hikvision Camera DS-2CD9111-S of V4.1.2 build 160203 and before, and this vulnerability allows remote attackers to launch a denial of service attack (service interruption) via a crafted network setting interface request.
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 vulnerability in Hikvision camera DS-2CD9111-S firmware V4.1.2 build 160203 and earlier allows remote attackers to cause denial of service via crafted network setting interface requests. This is a pre-authentication flaw enabling service interruption without credentials.

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 camera modelAccess the camera web interface, check ONVIF/UPnP device discovery, or use a network scanner to confirm the device is a Hikvision DS-2CD9111-S model.Affected if The device is a Hikvision DS-2CD9111-S camera.
-
Check the firmware version via web interfaceLog into the camera web interface and navigate to the System > Maintenance or System Info section to view the firmware version and build number.Affected if The firmware version displayed is V4.1.2 or earlier, with build number 160203 or lower.
-
Check firmware version via ONVIF or SNMPUse an ONVIF client tool or SNMP walk (if enabled) to query the device information and retrieve the firmware version metadata.Affected if The retrieved firmware version is <= V4.1.2 build 160203.
-
Verify the network setting interface is exposedConfirm the camera is accessible on the network by attempting to reach its HTTP/HTTPS management port (typically 80/443). The vulnerability exists in the network settings interface.Affected if The camera's web management interface is reachable on the network and the network settings functionality is accessible.
-
Confirm firmware build numberIn the camera firmware information page, locate both the version number (V4.1.2) and the specific build date (160203 represents YYMMDD format).Affected if The build number is 160203 or earlier, indicating the device is running a vulnerable firmware version.
A user is affected if the camera is a Hikvision DS-2CD9111-S model running firmware version V4.1.2 with build number 160203 or earlier, and the network management interface is accessible.

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 dataUpgrade Hikvision camera firmware to a version beyond V4.1.2 build 160203. If immediate patching is not feasible, restrict network access to the camera's management interface using firewall rules or network segmentation to limit exposure to untrusted networks.
