CVE-2023-27014Network attack vector

Unauthenticated code execution via stack overflow

Published Apr 7, 2023 · Updated Feb 12, 2025

Stack overflow in sub_46AC38 in Tenda AC10 firmware 16.03.10.13_cn allows remote attackers to execute code or crash via a crafted payload. The public record names the affected function but does not disclose the input field or unsafe memory operation that overruns the stack. No authentication or user interaction is required; successful exploitation corrupts memory, enabling code execution or a router crash.
