CVE-2025-4441Network attack vector

Memory corruption via oversized curTime parameter

Published May 8, 2025 · Updated May 9, 2025

Buffer overflow in D-Link DIR-605L 2.13B01 allows remote authenticated users to corrupt memory via a crafted curTime parameter. The formSetWAN_Wizard534 handler processes curTime without an effective length bound, although public records do not identify the copy operation or destination buffer. The CNA assessment requires low-privilege access; public evidence demonstrates neither code execution nor a deterministic crash.
