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
IP-COM M50 V15.11.0.33(10768) was discovered to contain a buffer overflow via the rules parameter in the formIPMacBindAdd function.

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 confidence

A buffer overflow vulnerability exists in the IP-COM M50 router firmware version 15.11.0.33(10768). The overflow occurs in the formIPMacBindAdd function through manipulation of the 'rules' parameter, allowing potential remote code execution or service disruption.

MitigationApply the vendor-supplied firmware patch or update to a non-vulnerable version. If no patch exists, consider network segmentation to limit exposure and disable the affected IP/MAC binding feature until a fix is available.

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 the device model
    Check the router model number on the device label or through the web management interface (typically accessed at 192.168.0.1 or 192.168.1.1). Look for 'M50' in the model identification.
    Affected if The device is not an IP-COM M50 router, then this CVE does not apply.
  2. Determine the firmware version
    Access the router web management interface and navigate to System Settings or Status page to view the firmware version. The version number is typically displayed as 15.11.0.33(10768) or similar.
    Affected if The firmware version is exactly 15.11.0.33, proceed to the next check. If the version differs, the device may not be affected by this specific CVE.
  3. Verify IP/MAC binding feature availability
    In the router web interface, locate the IP/MAC binding feature (often found under Security settings, Access Control, or IP filtering sections). Check if this feature is enabled or accessible.
    Affected if The IP/MAC binding feature exists and is accessible. The vulnerability exists in the formIPMacBindAdd function which handles this feature, so if the feature is present, the vulnerable code path exists.
  4. Check for signs of exploitation
    Review router logs for unusual formIPMacBindAdd function calls, unexpected restarts, or service disruptions. Look for abnormally long 'rules' parameter values in any logged HTTP requests.
    Affected if Unexplained service issues or suspicious log entries related to IP/MAC binding functionality are present, indicating potential exploitation attempts.

You are affected if you are running an IP-COM M50 router with firmware version 15.11.0.33 and the IP/MAC binding feature is accessible on the device.
