CVE-2018-3877

Estado: ModificadaCrítica (9.9)—

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.
