An exploitable buffer overflow vulnerability exists in the Samsung WifiScan handler of video-core's HTTP server of Samsung SmartThings Hub STH-ETH-250 - Firmware version 0.20.17. The strcpy overflows the destination buffer, which has a size of 40 bytes. An attacker can send an arbitrarily long "password" value in order to exploit this vulnerability.
The product copies an input buffer to an output buffer without verifying that the size of the input buffer is less than the size of the output buffer, leading to a buffer overflow.
