Root code execution via httpd stack overflow
Published Mar 28, 2023 · Updated Feb 19, 2025
Stack-based buffer overflow in TP-Link TL-WR940N 3.20.1 Build 200316 Rel.34392n (5553) allows remote authenticated users to execute code. The httpd ssid1 handler copies user-supplied data into a fixed-length stack buffer without first validating its length. Access to the router's adjacent network and authenticated management interface is required, and successful exploitation executes code as root.
