CVE-2022-32385Public exploitNetwork attack vector

Remote code execution via stack buffer overflow

Published Jul 6, 2022 · Updated Jul 9, 2026

Stack-based buffer overflow in Tenda AC23 firmware 16.03.07.44 allows remote attackers to execute arbitrary code via network requests. The CNA record and referenced exploit artifacts do not identify the affected function, request field, or unsafe copy operation. No authentication or user interaction is required, and successful exploitation runs attacker-controlled code on the router.
