CVE-2007-1435
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 · uneditedBuffer overflow in D-Link TFTP Server 1.0 allows remote attackers to cause a denial of service (crash) via a long (1) GET or (2) PUT request, which triggers memory corruption. NOTE: the provenance of this information is unknown; the details are obtained solely from third party information.
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 confidenceBuffer overflow vulnerability in D-Link TFTP Server 1.0 allows remote attackers to cause denial of service via long GET or PUT requests that trigger memory corruption. The vulnerability affects the TFTP service handling file transfer requests.

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 TFTP Server installationCheck installed programs or look for tftpserver.exe on the system. Verify the version number in the program's properties or documentation.Affected if D-Link TFTP Server version 1.0 is installed on the system
-
Confirm TFTP service is runningOpen Windows Services or use command 'sc query' or 'tasklist' to check if a TFTP server process is active.Affected if The TFTP service process is currently running on the system
-
Verify UDP port 69 is listeningRun 'netstat -an | findstr :69' or use a port scanner to check if UDP port 69 is bound to a listening socket.Affected if UDP port 69 is in a LISTENING or ESTABLISHED state indicating the TFTP server is accessible on the network
-
Check network exposure of TFTP portReview firewall rules or network configuration to determine if UDP port 69 is open to untrusted or remote network segments.Affected if The TFTP service (UDP 69) is accessible from network addresses outside the trusted local network
A system is affected if D-Link TFTP Server version 1.0 is installed, the TFTP service is running, and the service is exposed to network access where remote attackers could send crafted GET/PUT requests.
Generated from the published advisory. Verify against your own configuration.
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 dataIf a vendor patch is available, apply it immediately. Otherwise, disable the TFTP service if not required, or restrict network access to the TFTP port (UDP 69) using firewall rules to prevent untrusted remote access.
