Summary

A buffer overflow vulnerability exists in the handling of WiFiScan requests by the HTTP server of the Samsung SmartThings Hub. Specifically, an exploitable flaw arises from the improper handling of the 'cameraIp' parameter, allowing attackers to send excessively long input that overflows the destination buffer, which is limited to 40 bytes in size. This can lead to potential execution of arbitrary code or denial of service, thereby compromising the affected device's functionality and security.

Affected Version(s)
