What is CVE-2020-14077?

The TRENDnet TEW-827DRU is vulnerable to a stack-based buffer overflow in the ssi binary due to improper handling of user input in the apply.cgi script. An authenticated user can exploit this vulnerability by sending a specially crafted POST request to the set_sta_enrollee_pin_wifi1 or set_sta_enrollee_pin_wifi0 actions with an excessively long wps_sta_enrollee_pin key. This can lead to arbitrary code execution, enabling the attacker to execute malicious commands or gain unauthorized access to the device.
