Authenticated code execution via rebootTime stack overflow
Published Apr 23, 2024 · Updated Aug 1, 2024
Stack-based buffer overflow in Tenda AC8 16.03.34.09 allows remote authenticated users to crash the router or execute code. The formSetRebootTimer handler processes an overlong rebootTime value from /goform/SetRebootTimer without an effective length bound; the public disclosure does not identify the exact copy operation or buffer size. Valid management credentials and network access to the router interface are required, and successful exploitation can crash the management service or compromise the device.
