TITLE

Samsung SmartThings Hub STH-ETH-250 In firmware HTTP Request smuggling vulnerability

Trust: 0.8

sources: JVNDB: JVNDB-2018-009305

DESCRIPTION

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. SamsungSmartThingsHub is a smart home management device from South Korea's Samsung. video-coreHTTPserver is one of the HTTP servers. A security vulnerability exists in the REST resolver for the video-coreHTTP server in SamsungSmartThingsHub, which stems from a program failing to properly handle requests that are transmitted in a pipeline
