Authenticated management-interface crash via oversized multipart upload

Published Aug 31, 2026 · Updated Aug 31, 2026

Out-of-bounds write in D-Link DSM-G600 1.01 allows remote authenticated users to crash the HTTP management daemon via a multipart upload.

A valid HTTP Basic administrator login and network access to the management interface are required; code execution has not been established.
