This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Samsung Galaxy S9 prior to January 2019 Security Update (SMR-JAN-2019 - SVE-2018-13467). User interaction is required to exploit this vulnerability in that the target must connect to a wireless network. The specific flaw exists within the captive portal. By manipulating HTML, an attacker can force a page redirection. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-7476.

In the seccomp implementation prior to kernel version 4.8, there is a possible seccomp bypass due to seccomp policies that allow the use of ptrace. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.

An exploitable stack-based buffer overflow vulnerability exists in the retrieval of a database field in video-core's HTTP server of Samsung SmartThings Hub. The video-core process insecurely extracts the shard.videoHostURL field from its SQLite database, leading to a buffer overflow on the stack. An attacker can send an HTTP request to trigger this vulnerability.

An exploitable buffer overflow vulnerability exists in the /cameras/XXXX/clips handler of video-core's HTTP server of Samsung SmartThings Hub STH-ETH-250-Firmware version 0.20.17. The strncpy call overflows the destination buffer, which has a size of 52 bytes. An attacker can send an arbitrarily long "startTime" value in order to exploit this vulnerability.

An exploitable buffer overflow vulnerability exists in the credentials handler of video-core's HTTP server of Samsung SmartThings Hub STH-ETH-250-Firmware version 0.20.17. The strncpy 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.

An exploitable buffer overflow vulnerability exists in the Samsung WifiScan handler of video-core's HTTP server of Samsung SmartThings Hub STH-ETH-250 - Firmware version 0.20.17. The strcpy overflows the destination buffer, which has a size of 40 bytes. An attacker can send an arbitrarily long "cameraIp" value in order to exploit this vulnerability.

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 136 bytes. An attacker can send an arbitrarily long 'directory' value in order to exploit this vulnerability. An attacker can send an HTTP request to trigger this vulnerability.

An exploitable integer underflow vulnerability exists in the ZigBee firmware update routine of the hubCore binary of the Samsung SmartThings Hub STH-ETH-250 - Firmware version 0.20.17. The hubCore process incorrectly handles malformed files existing in its data directory, leading to an infinite loop, which eventually causes the process to crash. An attacker can send an HTTP request to trigger this vulnerability.

An exploitable 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 messages to SmartThings' remote servers, which incorrectly handle camera IDs for the 'sync' operation, leading to arbitrary deletion of cameras. An attacker can send an HTTP request to trigger this vulnerability.

An exploitable buffer overflow vulnerability exists in the camera 'update' feature of video-core's HTTP server of Samsung SmartThings Hub STH-ETH-250 - Firmware version 0.20.17. The video-core process incorrectly extracts fields from a user-controlled JSON payload, leading to a buffer overflow on the stack. An attacker can send an HTTP request to trigger this vulnerability.
