CVE-2018-3907: Samsung Sth-Eth-250 Firmware

Critical severity, CVSS 10.0. EPSS: 1.4% 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, 'on_url' callback. An attacker can send an HTTP request to trigger this vulnerability.
