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
D-Link Go-RT-AC750 GORTAC750_A1_FW_v101b03 contains a stack-based buffer overflow via the function hnap_main. An attacker can send a POST request to trigger the vulnerablilify.

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

Stack-based buffer overflow in the hnap_main function of D-Link Go-RT-AC750 firmware v101b03 allows remote, unauthenticated attackers to execute arbitrary code via a crafted HTTP POST request due to improper bounds checking when handling HN

MitigationThis is an end-of-life device with no vendor patch available; mitigate by isolating the device behind a firewall, disabling WAN access, or replacing with a supported router model.

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 device label or login to the router admin interface to confirm the model is D-Link Go-RT-AC750
    Affected if The device is not a D-Link Go-RT-AC750 unit, then this specific CVE does not apply
  2. Check the firmware version
    Access the router admin interface (typically at 192.168.0.1), navigate to Status or System settings, and locate the firmware version field
    Affected if The firmware version is 101b03, indicating the exact affected version
  3. Verify HNAP functionality is enabled
    In the router admin interface, look for HNAP (Home Network Administration Protocol) settings typically under Advanced or Network settings. Confirm the feature is accessible or enabled.
    Affected if HNAP is enabled and accessible on the device (the vulnerability exists in the hnap_main function)
  4. Confirm network accessibility of the router interface
    Attempt to access the router's web interface from the network segment where the router is deployed
    Affected if The router admin interface is reachable from a network segment where unauthenticated attackers could send HTTP POST requests

You are affected if you have a D-Link Go-RT-AC750 device running firmware version 101b03 with HNAP functionality enabled and accessible from a network where attackers could send crafted HTTP POST requests.
