CVE-2018-3911

CVE-2018-3911 affects Samsung SmartThings Hub STH-ETH-250 (firmware 0.20.17). The hubCore process listens on port 39500 and forwards unauthenticated JSON to remote SmartThings servers, which mishandle JSON and can inject CRLF into HTTP requests sent to the internal video-core HTTP server. This en...

CVE-2018-3856

CVE-2018-3856 affects Samsung SmartThings Hub STH-ETH-250 (firmware 0.20.17). Cisco Talos reports an OS command-injection in the video-core RTSP handling: if the camera-password contains spaces, the hub builds an ffmpeg command with attacker-controlled options, leading to arbitrary code execution...

CVE-2018-3880

CVE-2018-3880 affects Samsung SmartThings Hub STH-ETH-250 with Firmware 0.20.17. The vulnerability is a stack-based buffer overflow in the video-core HTTP server’s database function find-by-cameraId, triggered by crafting HTTP requests that interact with the SQLite data when deleting/handling cam...

CVE-2018-3912

On Samsung SmartThings Hub STH-ETH-250 devices with firmware version 0.20.17, the video-core process insecurely extracts the fields from the "shard" table of its SQLite database, leading to a buffer overflow on the stack. The strcpy call overflows the destination buffer, which has a size of 128...

CVE-2018-3912

CVE-2018-3912 affects Samsung SmartThings Hub STH-ETH-250 firmware 0.20.17. The video-core HTTP server copies database fields from shard into a stack-allocated structure using strcpy without length checks, enabling stack-based buffer overflows (secretKey, plus other fields with varying sizes). An...
