An exploitable vulnerability exists in the remote servers of Samsung SmartThings Hub STH-ETH-250 - Firmware version 0.20.17. The hubCore process listens on port 39500 and relays any unauthenticated messages to SmartThings remote servers, which incorrectly handle camera IDs for the sync operation, leading to arbitrary deletion of cameras. An attacker can send an HTTP request to trigger this vulnerability.

Weakness

The product does not ensure or incorrectly ensures that structured messages or data are well-formed and that certain security properties are met before being read from an upstream component or sent to a downstream component.

Extended Description

If a message is malformed, it may cause the message to be incorrectly interpreted. Neutralization is an abstract term for any technique that ensures that input (and output) conforms with expectations and is “safe.” This can be done by:

This weakness typically applies in cases where the product prepares a control message that another process must act on, such as a command or query, and malicious input that was intended as data, can enter the control plane instead. However, this weakness also applies to more general cases where there are not always control implications.
