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
Team ENVY, a Security Research TEAM has found a flaw that allows for a remote code execution on the camera. An attacker could inject malicious into http request packets to execute arbitrary code. The manufacturer has released patch firmware for the flaw, please refer to the manufacturer's report for details and workarounds.

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 · moderate confidence

A vulnerability in camera firmware allows remote attackers to inject malicious code through HTTP request packets, enabling arbitrary code execution without authentication. The attack vector is remote via HTTP, making exploitation straightforward for network-adjacent attackers.

MitigationApply the manufacturer-released patch firmware to all affected camera devices immediately. If patching is delayed, restrict network access to camera management interfaces and disable unnecessary HTTP-exposed services.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify camera devices on your network
    Inventory all network-connected camera devices by scanning your network for devices on typical camera ports (rtsp, http, https) or using network discovery tools. Document the manufacturer, model, and firmware version of each device.
    Affected if You have IP cameras from manufacturers that have not released patches for CVE-2023-6116, and the firmware version is unknown or falls within the vulnerable range.
  2. Check camera firmware version
    Access each camera's web interface or administrative console and locate the firmware version information, typically found under Settings, System, or About sections. Compare your installed version against any vendor-released version information for CVE-2023-6116.
    Affected if The installed firmware version is older than the patched version released by your camera manufacturer for this vulnerability.
  3. Verify HTTP service status
    Check if the camera's HTTP management interface is enabled. This is typically configurable in the camera's network settings. Confirm whether port 80 or 80xx is listening on the camera device.
    Affected if HTTP service is enabled and exposed, making the device reachable via HTTP for remote attack vectors.
  4. Assess network exposure
    Review firewall rules and network segmentation to determine if camera management interfaces are accessible from untrusted networks. Check if cameras are directly exposed to the internet or on insufficiently isolated network segments.
    Affected if Camera HTTP interfaces are accessible from outside your trusted network, allowing remote attackers to send malicious HTTP packets.
  5. Examine logs for suspicious HTTP requests
    Review camera system logs, web server logs, or network intrusion detection alerts for unusual or malformed HTTP requests, especially those containing unexpected characters, command injection patterns, or requests to unfamiliar endpoints.
    Affected if Logs show HTTP requests containing potential injection payloads or unexpected commands that may indicate exploitation attempts.

You are affected if you have camera devices with firmware vulnerable to CVE-2023-6116 and their HTTP management interfaces are network-accessible to remote attackers.
