CVE-2019-17146

Unauthenticated code execution via SOAPAction stack overflow

Published Jan 7, 2020 · Updated Aug 5, 2024

Stack-based buffer overflow in D-Link DCS-960L before 1.09 allows remote attackers on the local network to execute code as admin. The HNAP service on TCP port 80 copies an oversized SOAPAction request header into a stack buffer without first validating its length. The service is reachable without authentication from the LAN side, and successful exploitation runs attacker-controlled code as the admin user.
