CVE-2018-3907 is a critical-severity vulnerability rated 10/10 on the CVSS scale. 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. EPSS estimates a 1.44% chance of exploitation in the next 30 days.
