CVE-2015-2052
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 · uneditedStack-based buffer overflow in the DIR-645 Wired/Wireless Router Rev. Ax with firmware 1.04b12 and earlier allows remote attackers to execute arbitrary code via a long string in a GetDeviceSettings action to the HNAP interface.
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 confidenceStack-based buffer overflow in D-Link DIR-645 routers (firmware 1.04b12 and earlier) in the HNAP interface's GetDeviceSettings action allows remote attackers to execute arbitrary code via a long string, achieving maximum severity (CVSS 10).

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 router modelAccess the router's web administration interface or check the device label/marketing materials to confirm the exact model is D-Link DIR-645Affected if The device is not a D-Link DIR-645 model, then it is not affected by this specific CVE
-
Check the installed firmware versionLog into the router web interface and navigate to the Status or Management section to view the firmware version; alternatively, check the firmware file name if you have direct access to the firmware binaryAffected if The firmware version is 1.04b12 or earlier, meaning it falls within or below the affected version range
-
Verify HNAP interface accessibilityAttempt to access the HNAP interface by sending an HTTP request to the router's IP address at the /HNAP1/ endpoint (for example: http://<router-ip>/HNAP1/)Affected if The HNAP interface responds with a SOAP or XML-based service description, indicating the interface is enabled and reachable
-
Test GetDeviceSettings action availabilitySend a crafted SOAP request to the HNAP interface targeting the GetDeviceSettings action, typically by posting to /HNAP1/ with an XML payload containing <GetDeviceSettings/>Affected if The router returns a response to the GetDeviceSettings action, confirming the vulnerable function is exposed
If the device is a D-Link DIR-645 running firmware version 1.04b12 or earlier AND the HNAP interface is accessible and responding to the GetDeviceSettings action, then the environment is affected by this vulnerability.

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 firmware update if available from vendor; otherwise, disable or restrict access to the HNAP interface via firewall rules or network segmentation to prevent external exploitation.
