What is CVE-2020-14080?

The TRENDnet TEW-827DRU devices running firmware version 2.06B04 are susceptible to a stack-based buffer overflow due to improper input handling in the ssi binary. An unauthenticated user can exploit this vulnerability by sending crafted POST requests to the apply_sec.cgi endpoint, specifically using the action ping_test. If the input exceeds the expected length for the ping_ipaddr key, it can lead to arbitrary code execution, posing significant security risks to affected devices.
