CVE-2024-36831
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 · uneditedA NULL pointer dereference in the plugins_call_handle_uri_clean function of D-Link DAP-1520 REVA_FIRMWARE_1.10B04_BETA02_HOTFIX allows attackers to cause a Denial of Service (DoS) via a crafted HTTP request without authentication.
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 confidenceA NULL pointer dereference vulnerability exists in the plugins_call_handle_uri_clean function of D-Link DAP-1520 wireless range extender firmware. The vulnerability can be triggered by sending a crafted HTTP request to the device without requiring authentication, causing the service to crash and resulting in Denial of Service.

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.
-
Confirm device modelAccess the device's web management interface or check the device label to verify it is a D-Link DAP-1520 wireless range extenderAffected if Device is not a D-Link DAP-1520 model
-
Check firmware versionLog into the device web interface and navigate to the status or system information page to view the installed firmware version, or use the command line to query the system if accessibleAffected if Firmware version is 1.10b04
-
Verify HTTP service is accessibleAttempt to reach the device's web management interface over HTTP from the network by sending a request to the device IP address on port 80Affected if HTTP service is exposed and reachable on the network
-
Check if web service is responsiveSend an HTTP request to the device and observe whether the service responds or if it is crashed/unresponsive (indicating the vulnerability may have been exploited)Affected if Web service fails to respond or returns an error indicating a crash
User is affected if the device is a D-Link DAP-1520 running firmware version 1.10b04 and has its HTTP management interface exposed to the network.

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 vendor-supplied firmware patches when available. Until then, restrict network access to the device's management interface using firewall rules or network segmentation to prevent unauthorized HTTP requests from reaching the device.
