| 标题 | Tenda RX3 V16.03.13.11 Stack-based Buffer Overflow |
|---|
| 描述 | During a security review of the Tenda RX3 router firmware (version V16.03.13.11), a critical stack-based buffer overflow vulnerability was identified in the Wi-Fi configuration endpoint /goform/fast_setting_wifi_set.
The vulnerability exists within the form_fast_setting_wifi_set function. This function retrieves the user-controlled parameter ssid via the websGetVar interface and processes it into a fixed-size stack buffer ssid_5g (64 bytes). Due to the use of the unsafe sprintf 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. |
