CVE-2024-2894Public exploitNetwork attack vector

Router compromise via oversized QoS list parameter

Published Mar 26, 2024 · Updated Aug 15, 2024

Stack-based buffer overflow in Tenda AC7 15.03.06.44 allows remote authenticated users to compromise the router via a crafted list parameter. The formSetQosBand handler for /goform/SetNetControlList accepts an oversized list value and writes beyond its stack buffer. Low-privilege access to the network management interface is required, and successful exploitation can read or alter data or crash the service.
