High impact if exploited, but EPSS currently rates exploitation as unlikely (1.24%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

Description

An exploitable stack-based buffer overflow vulnerability exists in the database 'find-by-cameraId' functionality of video-core's HTTP server of Samsung SmartThings Hub STH-ETH-250 - Firmware version 0.20.17. The video-core process incorrectly handles existing records inside its SQLite database, leading to a buffer overflow on the stack. An attacker can send an HTTP request to trigger this vulnerability.
