CRITICAL 9.9EPSS 1.7%
On Samsung SmartThings Hub STH-ETH-250 devices with firmware version 0.20.17, the video-core process incorrectly extracts fields from a user-controlled JSON payload, leading to a buffer overflow on the stack. An attacker can send an HTTP request to trigger this vulnerability. A strcpy overflows the destination buffer, which has a size of 40 bytes. An attacker can send an arbitrarily long "user" value in order to exploit this vulnerability.
