Process-memory corruption via unchecked wpapsk_crypto copy
Published Jan 26, 2024 · Updated Sep 12, 2024
Stack-based buffer overflow in Tenda AC10U 15.03.06.49_multi_TDE01 allows remote authenticated users to corrupt process memory. The fromSetWirelessRepeat handler reads wpapsk_crypto with websGetVar and passes it to strcpy, which copies it into the fixed-size wpapsk_cryptovalue_0 stack buffer without a length check. Administrative access to the HTTP management endpoint is required; public evidence demonstrates the overwrite path but not code execution or a persistent service interruption.
