Name of the Vulnerable Software and Affected Versions Samsung SmartThings Hub version 0.20.17

Description A buffer overflow issue exists in the /cameras/XXXX/clips handler of the video-core's HTTP server. The video-core process incorrectly handles user-controlled JSON payloads, leading to a buffer overflow on the stack due to the strncpy call overflowing a 52-byte destination buffer. An attacker can exploit this by sending an arbitrarily long "callbackUrl" value.

Recommendations For Samsung SmartThings Hub version 0.20.17, consider restricting access to the /cameras/XXXX/clips handler until a patch is available. As a temporary workaround, avoid using arbitrarily long "callbackUrl" values in the 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.
