CWE-119

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 video-core process incorrectly extracts the videoHostUrl field 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.

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 128 bytes. An attacker can send an arbitrarily long “secretKey” 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 32 bytes. An attacker can send an arbitrarily long “accessKey” 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 video-core process incorrectly extracts fields from a user-controlled JSON payload, leading to a buffer overflow on the stack. The strncpy overflows the destination buffer, which has a size of 2,000 bytes. An attacker can send an arbitrarily long “sessionToken” 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 160 bytes. An attacker can send an arbitrarily long “directory” value in order to exploit this vulnerability.

Multiple exploitable buffer overflow vulnerabilities exist in the credentials handler of video-core’s HTTP server of 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. A strncpy 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.
