CVE-2002-1068
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 · uneditedThe web server for D-Link DP-300 print server allows remote attackers to cause a denial of service (hang) via a large HTTP POST request.
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 confidenceThe D-Link DP-300 print server's embedded web server contains a vulnerability where processing an excessively large HTTP POST request causes the device to hang, resulting in denial of service. This indicates improper bounds checking or resource management in the HTTP request handling code.

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 D-Link DP-300 device on networkSend an HTTP GET request to the device's web interface (port 80/tcp) and examine the Server header in the response, or use network scanning tools to fingerprint the device based on HTTP response patternsAffected if The device responds with HTTP headers indicating it is a D-Link print server or the device model matches DP-300/DP-303
-
Confirm web server is enabled and accessibleAttempt to access the device's HTTP service by browsing to its IP address or sending a curl/GET requestAffected if The web interface responds with any HTTP content, indicating the embedded web server is active
-
Check network exposure of the web interfaceReview firewall rules or network segmentation to determine if the device's HTTP port is accessible from untrusted networks or the internetAffected if The device's web interface is reachable from networks outside the local administrative subnet
-
Test for DoS condition with large POST requestSend an HTTP POST request with an excessively large Content-Length value (for example, several MB of data) to the device's web server endpoint and observe whether the device becomes unresponsiveAffected if After sending the large POST request, subsequent HTTP requests to the device fail or timeout, indicating the device has hung
A user is affected if they have an accessible D-Link DP-300/DP-300 print server on their network and sending a large HTTP POST request causes the device to stop responding.

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 dataSince the DP-300 is likely end-of-life with no patches available, remediation involves network isolation (placing the device behind a firewall with restricted access), disabling the web interface if unnecessary, or replacing the legacy device with a supported model.
