CVE-2024-0927Public exploitNetwork attack vector

Authenticated memory corruption via unbounded entrys formatting

Published Jan 26, 2024 · Updated May 29, 2025

Stack-based buffer overflow in Tenda AC10U 15.03.06.49_multi_TDE01 allows remote authenticated users to corrupt process memory via entrys. The fromAddressNat handler reads entrys with websGetVar and passes it to sprintf with other strings into a fixed-size stack buffer without checking the combined length. Administrative access to the network management interface is required, and the published proof of concept demonstrates the overflow but not code execution.
