CVE-2018-3878

Name of the Vulnerable Software and Affected Versions Samsung SmartThings Hub STH-ETH-250 version 0.20.17

Description The issue is related to multiple exploitable buffer overflow vulnerabilities in the credentials handler of the video-core's HTTP server. These vulnerabilities occur due to the incorrect extraction of fields from a user-controlled JSON payload, leading to a buffer overflow on the stack. Specifically, a strncpy operation overflows the destination buffer, which has a limited size of 16 bytes. An attacker can exploit this by sending an arbitrarily long "region" value.

Recommendations For Samsung SmartThings Hub STH-ETH-250 version 0.20.17, consider restricting access to the video-core's HTTP server until a patch is available. As a temporary workaround, avoid using the region variable in the affected JSON payload to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
