CVE-2023-24350Public exploitNetwork attack vector

Code execution via unbounded email-subject stack copy

Published Feb 10, 2023 · Updated Mar 24, 2025

Stack-based buffer overflow in D-Link DIR-605L firmware 2.13B01 allows remote authenticated users to execute code or crash the router. The boa HTTP server passes the arbitrarily long config.smtp_email_subject value from /goform/formSetEmail to sprintf, which copies it into stack memory without a length bound. Access requires logging in to the web interface; successful exploitation runs code in the HTTP-server context or interrupts that service.
