VAR-201808-0908
Vulnerability from variot - Updated: 2023-12-18 13:02On 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. Samsung SmartThings Hub STH-ETH-250 The 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. A buffer overflow vulnerability exists in the samsungWifiScanhandler of the video-coreHTTP server in SamsungSmartThingsHub. This vulnerability stems from the fact that the video-core process failed to properly extract the fields in the JSON payload controlled by the user
