CVE-2018-3913

An exploitable stack-based buffer overflow vulnerability exists in the retrieval of database fields in the video-core HTTP server of the Samsung SmartThings Hub STH-ETH-250 - Firmware version 0.20.17. The strcpy call overflows the destination buffer, which has a size of 32 bytes. An attacker can send an arbitrarily long "accessKey" value in order to exploit this vulnerability.
