CWE-119

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. An attacker can send an HTTP request to trigger this vulnerability. The strcpy call overflows the destination buffer, which has a size of 16 bytes. An attacker can send an arbitrarily long “region” value in order to exploit this vulnerability.

An exploitable buffer overflow vulnerability exists in the remote video-host communication of video-core’s HTTP server of Samsung SmartThings Hub STH-ETH-250 devices with firmware version 0.20.17. The video-core process insecurely parses the AWSELB cookie while communicating with remote video-host servers, leading to a buffer overflow on the heap. An attacker able to impersonate the remote HTTP servers could trigger this vulnerability.

On Samsung SmartThings Hub STH-ETH-250 devices with 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. A strcpy overflows the destination buffer, which has a size of 40 bytes. An attacker can send an arbitrarily long “user” 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 “password” 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 buffer overflow vulnerability exists in the samsungWifiScan handler 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. The strcpy at [8] overflows the destination buffer, which has a size of 40 bytes. An attacker can send an arbitrarily long ‘callbackUrl’ value in order to exploit this vulnerability.
