Authenticated code execution via unchecked SSID copy
Published Apr 9, 2024 · Updated Nov 4, 2025
Stack overflow in TP-Link EAP225 V3 5.1.0 Build 20220926 allows remote authenticated users to execute code through Radio Scheduling. The _http_wsche_saveAssocSsid function passes the unbounded ssid length to strncpy when filling a fixed-size stack structure. Administrative access to the scheduler POST endpoint is required; successful corruption grants code execution in a web service running as root.
