SwitchBot Firmware Update Sensitive Information Disclosure

CVE advisorySeverity: CRITICAL (CVSS 9.1)

CVE-2024-48786

The vulnerability exists within the firmware update process of a mobile application used for IoT device management. While the update mechanism may reach out to remote servers, the application itself is a client-side tool, and it is uncommon for the specific update process to be directly exposed as a public-facing service reachable by attackers over the internet.

Halo Surface Signal: 2 out of 5 — less likely to be public-facing.

Frequently asked questions

What is the SwitchBot application?

SwitchBot is a mobile application developed by SWITCHBOT INC designed to manage and control Internet of Things (IoT) smart home devices. It acts as a central hub for users to configure, monitor, and maintain their connected ecosystem. This specific vulnerability involves the software component responsible for managing firmware updates for these hardware devices.

How does CVE-2024-48786 manifest?

This vulnerability is classified as CWE-863, which relates to incorrect authorization. In the context of CVE-2024-48786, the application fails to properly secure the communication or data handling during its firmware update routine. This flaw allows a remote party to bypass intended security controls and access sensitive information that should remain protected while the app updates your connected hardware.

When is the firmware update process vulnerable?

The risk is tied to the specific network communication flow that occurs when the mobile application performs a firmware update for a SwitchBot device. It is important to note that simply having the app installed does not trigger the vulnerability; the exposure is tied to the active process of fetching or processing update data, which involves external network interaction.

Is my SwitchBot deployment at risk?

According to Halo Surface Signal, this risk is currently labeled as unlikely. Because the firmware update process is handled within a client-side mobile application rather than a public-facing server or service, it is generally not exposed to arbitrary attackers over the internet. You should focus on instances where the mobile device and its network environment are in a position to be targeted during the update cycle.

Do I need to take immediate action?

Begin by identifying where the SwitchBot application is deployed within your environment and determining who owns or manages these installations. Since this is an application-level concern, your first step is to confirm the scope of usage and assess whether any business-critical operations rely on these specific devices. Once mapped, monitor for official updates or guidance from the vendor to address the authorization flaw.
