Authenticated code execution via unchecked tmpServer copy
Published Feb 3, 2026 · Updated Feb 3, 2026
Stack-based buffer overflow in TP-Link Archer AX53 v1.0 through 1.3.1 Build 20241120 allows remote authenticated users to execute code. The tmpServer tpAPP_inf_parse_wifi_data function copies an attacker-controlled payload of up to 0x4000 bytes into a 0x400-byte stack buffer. Access requires authentication and a cloud-established SSH tunnel to the router's localhost service; exploitation crashes tmpServer or controls execution.
