CVE-2018-3911 describes an HTTP header injection vulnerability in the Samsung SmartThings Hub STH-ETH-250 (firmware version 0.20.17). This flaw allows an unauthenticated attacker to send specially crafted messages to the hub's port 39500, which are then insecurely relayed to remote SmartThings servers, leading to partially controlled requests against an internal video-core process. Rated 8.6 HIGH on CVSS, this vulnerability is network-exploitable with low attack complexity and no user interaction, potentially leading to high integrity impact. There is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage surrounding this CVE.
