CVE-2023-49908Network attack vector

Authenticated code execution via unchecked profile copy

Published Apr 9, 2024 · Updated Nov 4, 2025

Stack-based buffer overflow in TP-Link EAP225 5.1.0 Build 20220926 and EAP115 5.0.4 Build 20220216 allows remote authenticated users to execute code. The Radio Scheduling handler copies the profile POST parameter into fixed-size stack buffers without checking its length. Administrative web-interface credentials and a crafted request to /data/scheduler.association.json are required; corruption grants root-level code execution.
