Unauthenticated stack overflow via oversized funcpara1
Published Mar 29, 2024 · Updated Mar 25, 2025
Stack overflow in Tenda F1202 1.2.0.20(408) allows remote attackers to corrupt memory through a crafted funcpara1 request. The formSetCfm handler copies attacker-controlled funcpara1 data into a stack buffer without verifying that the destination is large enough. No authentication or user interaction is required, and triggering the overflow can crash the router or permit control of the affected process.
