An exploitable stack-based buffer overflow vulnerability exists in the retrieval of database fields in the video-core HTTP server of the Samsung SmartThings Hub STH-ETH-250 – Firmware version 0.20.17. The strcpy call overflows the destination buffer, which has a size of 64 bytes. An attacker can send an arbitrarily long “bucket” value in order to exploit this vulnerability.
CVE-2018-3914
An exploitable stack-based buffer overflow vulnerability exists in the retrieval of database fields in the video-core HTTP server of the Samsung SmartThings Hub STH-ETH-250 – Firmware version 0.20.17. The strcpy call overflows the destination buffer, which has a size of 2000 bytes. An attacker can send an arbitrarily long “sessionToken” value in order to exploit this vulnerability.
CVE-2018-3913
An exploitable stack-based buffer overflow vulnerability exists in the retrieval of database fields in the video-core HTTP server of the Samsung SmartThings Hub STH-ETH-250 – Firmware version 0.20.17. The strcpy call overflows the destination buffer, which has a size of 32 bytes. An attacker can send an arbitrarily long “accessKey” value in order to exploit this vulnerability.
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 bytes. An attacker can send an arbitrarily long “secretKey” value in order to exploit this vulnerability.
CVE-2018-3911
An exploitable HTTP header injection vulnerability exists in the remote servers of Samsung SmartThings Hub STH-ETH-250 – Firmware version 0.20.17. The hubCore process listens on port 39500 and relays any unauthenticated message to SmartThings’ remote servers, which insecurely handle JSON messages, leading to partially controlled requests generated toward the internal video-core process. An attacker can send an HTTP request to trigger this vulnerability.
CVE-2018-3910
An exploitable code execution vulnerability exists in the cloud OTA setup functionality of Yi Home Camera 27US 1.8.7.0D. A specially crafted SSID can cause a command injection, resulting in code execution. An attacker can cause a camera to connect to this SSID to trigger this vulnerability. Alternatively, an attacker can convince a user to connect their camera to this SSID.
