Title: Tenda RX3 V16.03.13.11 Stack-based Buffer Overflow Description: A critical stack-based buffer overflow vulnerability was identified in the Wi-Fi configuration endpoint of Tenda RX3 router firmware (version V16.03.13.11). The vulnerability exists in the function. This function retrieves the user-controlled parameter via the interface and processes it into a fixed-size stack buffer (64 bytes). Due to the use of the unsafe function without length validation, an attacker can provide an overly long SSID to overwrite the stack, leading to a Denial of Service (DoS) or arbitrary code execution with root privileges.
