CVE-2024-0922Public exploitNetwork attack vector

Memory corruption via unchecked PPPoE password decoding

Published Jan 26, 2024 · Updated Jun 11, 2025

Stack-based buffer overflow in Tenda AC10U 15.03.06.49_multi_TDE01 allows remote attackers to corrupt memory via a PPPoE password. The /goform/QuickIndex handler passes PPPOEPassword from websGetVar to decodePwd without a length check, and decodePwd copies filtered bytes into the fixed-size decode_pwd stack array. Published assessments disagree on the authentication gate, and the proof of concept establishes the overflow but demonstrates neither code execution nor a reliable service crash.
