CVE-2023-49912Public exploitNetwork attack vector

Authenticated code execution via unbounded profile copy

Published Apr 9, 2024 · Updated Nov 4, 2025

Stack-based buffer overflow in TP-Link EAP225 and EAP115 Radio Scheduling allows remote authenticated users to execute code via HTTP. The httpd handler passes each newline-delimited profile value to strcpy_until, which copies it into a 32-byte stack buffer without checking input length. Access to the authenticated web interface is required; a crafted request can corrupt the stack and execute code with the access point's privileges.
