CVE-2018-3863

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

Description The issue arises from the incorrect extraction of fields from a user-controlled JSON payload by the video-core process, leading to a buffer overflow on the stack. This can be triggered by sending an HTTP request. Specifically, a strcpy operation overflows a destination buffer of 40 bytes. An attacker can exploit this by sending an arbitrarily long user value.

Recommendations For Samsung SmartThings Hub STH-ETH-250 version 0.20.17, as a temporary workaround, consider restricting access to the video-core process until a patch is available. Avoid using arbitrarily long user values in HTTP requests to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
