Authenticated code execution via curTime buffer overflow
Published Apr 10, 2026 · Updated Apr 10, 2026
Buffer overflow in D-Link DIR-513 1.10 allows remote authenticated users to corrupt memory via a crafted curTime POST parameter. The formSetRoute handler at /goform/formSetRoute copies curTime into a fixed-size buffer without verifying its length. Low-privileged web-management access is required; successful exploitation can alter execution or crash the end-of-life router.
