The video-core process incorrectly extracts fields from a user-controlled JSON payload, leading to a buffer overflow on the stack. The strcpy at [8] overflows the destination buffer, which has a size of 40 bytes. An attacker can send an arbitrarily long 'callbackUrl' value in order to exploit this vulnerability."},{"lang":"es","value":"Existe un desbordamiento de búfer explotable en el manipulador samsungWifiScan del servidor HTTP de video-core de Samsung SmartThings Hub STH-ETH-250 en su versión de firmware 0.20.17.
