CVE-2024-0537Network attack vector

Authenticated service interruption via ssidIndex stack overflow

Published Jan 15, 2024 · Updated Aug 27, 2024

Stack-based buffer overflow in Tenda W9 1.0.0.7(4456) allows remote authenticated users to corrupt httpd execution via a crafted ssidIndex value. The httpd setWrlBasicInfo function processes the attacker-controlled ssidIndex value without preventing it from overflowing a stack buffer. Low-privileged network access is required, and successful exploitation can interrupt service or compromise data and device state.
