CVE-2018-3909: Samsung Sth-Eth-250 Firmware

High severity, CVSS 8.6. EPSS: 1.3% chance of exploitation in the next 30 days.

An exploitable vulnerability exists in the REST parser of video-core's HTTP server of the Samsung SmartThings Hub STH-ETH-250 - Firmware version 0.20.17. The video-core process incorrectly handles pipelined HTTP requests, which allows successive requests to overwrite the previously parsed HTTP method, 'onmessagecomplete' callback. An attacker can send an HTTP request to trigger this vulnerability.
