CVE-2024-4116Public exploitNetwork attack vector

Authenticated memory corruption via unbounded DHCP index

Published Apr 24, 2024 · Updated Aug 1, 2024

Stack-based buffer overflow in Tenda W15E 15.11.0.14 allows remote authenticated users to corrupt memory via delDhcpIndex. The formDelDhcpRule handler for /goform/DelDhcpRule fails to limit the parameter before placing it in a stack buffer. Low-privilege access to the management endpoint is required; the record establishes memory corruption but not whether it yields code execution or only a crash.
