# CVE-2018-3893

> 9.9 CRITICAL

## Beschreibung

An exploitable buffer overflow vulnerability exists in the /cameras/XXXX/clips handler of video-core's HTTP server of Samsung SmartThings Hub STH-ETH-250 - 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.
