Authenticated service disruption via unbounded time parsing
Published Jan 26, 2024 · Updated Nov 13, 2024
Stack-based buffer overflow in Tenda AC10U 15.03.06.49_multi_TDE01 allows remote authenticated users to disrupt the router via a crafted time value. setSmartPowerManagement reads time with websGetVar and passes it to sscanf with unbounded scansets, overflowing four fixed-size stack buffers. Administrative access is required, and the public PoC establishes the overwrite path but does not demonstrate code execution.
