CVE-2023-24347Public exploitNetwork attack vector

Authenticated code execution via unbounded webpage copy

Published Feb 10, 2023 · Updated Mar 24, 2025

Stack-based buffer overflow in D-Link DIR-605L 2.13B01 BETA allows remote authenticated users to execute code via a crafted webpage parameter. The boa HTTP server copies the arbitrarily long value through strcpy into last_url and later passes it to sprintf on the stack without a length bound. Access to the web configuration interface and valid credentials are required; exploitation can execute arbitrary code or crash the service.
