提出 #773619: Tenda A18pro V02.03.02.28 stack情報

タイトルTenda A18pro V02.03.02.28 stack
説明During a security review of the Tenda A18pro router firmware (version V02.03.02.28), 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.
