CVE-2024-4291Network attack vector

Authenticated memory corruption via deviceList stack overflow

Published Apr 27, 2024 · Updated Aug 27, 2025

Stack-based buffer overflow in formAddMacfilterRule in Tenda A301 15.13.08.12_multi_TDE01 allows remote authenticated users to corrupt memory. The /goform/setBlackRule handler accepts a crafted deviceList value that overruns the function's stack buffer; the public record does not identify the exact unsafe operation. Low-privileged access to the network management interface is required, and successful exploitation can compromise device confidentiality, integrity, and availability.
