CVE-2026-6012Public exploitNetwork attack vector

Authenticated memory corruption via oversized curTime input

Published Apr 10, 2026 · Updated Apr 10, 2026

Buffer overflow in D-Link DIR-513 1.10 allows remote authenticated users to corrupt memory through a crafted management POST request. The formSetPassword handler processes the curTime parameter at /goform/formSetPassword without adequate bounds enforcement, overflowing its destination buffer. Low-privileged management access is required; public records do not establish whether exploitation causes a crash or code execution.
