CVE-2025-6614Public exploitNetwork attack vector

Authenticated code execution via unbounded curTime copy

Published Jun 25, 2025 · Updated Jun 26, 2025

Stack-based buffer overflow in D-Link DIR-619L 2.06B01 allows remote authenticated users to execute code via a crafted curTime value. The boa handler formSetWANType_Wizard5 copies the unbounded curTime POST parameter into a stack local, overwriting the saved return address. Access to LAN-side web configuration is required; the demonstrated request crashes the router, while return-address control enables code execution.
