A buffer overflow vulnerability exists in the 'replace' feature of the HTTP server in Samsung's SmartThings Hub STH-ETH-250 devices running firmware version 0.20.17. This issue arises from improper extraction of a user-controlled JSON payload's URL field, which may result in a buffer overflow on the stack. An attacker capable of sending a crafted HTTP request could exploit this vulnerability to execute arbitrary code on the affected device, potentially compromising the security of the smart home environment.
