High impact if exploited, but EPSS currently rates exploitation as unlikely (1.55%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
An exploitable JSON injection vulnerability exists in the credentials handler of video-core's HTTP server of Samsung SmartThings Hub STH-ETH-250 devices with firmware version 0.20.17. The video-core process incorrectly parses the user-controlled JSON payload, leading to a JSON injection which in turn leads to a SQL injection in the video-core database. An attacker can send a series of HTTP requests to trigger this vulnerability.
