Authenticated service interruption via oversized submit-url
Published Jun 16, 2025 · Updated Jun 16, 2025
Buffer overflow in TOTOLINK EX1200T 4.1.2cu.5232_B20210713 allows remote authenticated users to interrupt service via a crafted HTTP POST. The /boafrm/formWirelessTbl handler passes the attacker-controlled submit-url value to sub_4400E4 without enforcing a safe buffer length. A valid sessionCheck token is required, and the published proof of concept demonstrates denial of service rather than code execution or persistent device damage.
