Technical 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, 'onmessagecomplete' callback. An attacker can send an HTTP request to trigger this vulnerability.
Remediation
Check the references section for vendor advisories and patches from samsung. Update sth-eth-250_firmware to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
