CVE-2024-4963Public exploitNetwork attack vector

Authenticated file write via unrestricted upload

Published May 16, 2024 · Updated Aug 1, 2024

Unrestricted file upload in D-Link DAR-7000-40 V31R02B1413C allows remote authenticated users to write files via /url/url.php. The handler accepts the file_upload argument and stores attacker-supplied content without restricting dangerous file types. Low-privileged access to the network-facing interface is required, and uploaded content can modify appliance files; public sources do not establish code execution.
