sources: JVNDB: JVNDB-2018-009552

DESCRIPTION

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. Samsung SmartThings Hub STH-ETH-250 - Firmware Contains a buffer error vulnerability.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. SamsungSmartThingsHub is a smart home management device from South Korea's Samsung. video-coreHTTPserver is one of the HTTP servers. samsungWifiScanhandler is one of the WiFi network discovery handlers
