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

Description A stack-based buffer overflow issue exists in the video-core HTTP server due to the retrieval of database fields. Specifically, the strcpy call overflows a destination buffer of size 32 bytes. An attacker can exploit this by sending an arbitrarily long value for the accessKey variable.

As a temporary workaround, avoid using excessively long values for the accessKey variable in requests to the server.
