This vulnerability exists due to the fact that the WBM does not properly sanitize user input before using it. An attacker could trick a user into installing a malicious ROM update that would cause an application messaging vulnerability. An attacker could also use this vulnerability to install a malicious ROM update and then use an application messaging vulnerability to send messages to a targeted account to exfiltrate data and steal cryptocurrency. Visit the firmware update page on the Baxter website to learn more about updated ROM versions for each WBM model. End users can also install the latest version of the ROMM32 application, which will automatically download and install updates. Users can also install the latest version of the ROMM33 application, which will also automatically download and install updates.

Executive Summary - BENDIX
Baxter Healthcare's line of Warrior Modular Input Output (WBM) devices are vulnerable to a software update installation vulnerability that could allow an attacker to steal cryptocurrency. The vulnerability exists due to the fact that the WBM does not properly sanitize user input before using it. This would allow an attacker to trick a user into installing a malicious ROM update that would cause an application messaging vulnerability. An attacker could also use this vulnerability to install a malicious ROM update and then use an application messaging vulnerability to send messages to a targeted account to exfiltrate data and steal cryptocurrency.
Operation mitigations
To mitigate this vulnerability, ensure that your network is secure. Consider using a VPN on your device. This will help to protect you against potential attacks on your device. Ensure that your software is up-to-date and contains the latest security patches and ROM updates. Disable any application messaging features in the ROM update settings for your WBM model and disable all unused features in Baxter's ROM update page (for example, if you have a WBMV7, do not enable the "WS upgrade" feature).

Vulnerabilities in the ROMM32 and ROMM33 Applications
The ROMM32 and ROMM33 applications are vulnerable to the following vulnerabilities:
1. The ROMM32 application does not properly sanitize input before sending it to the WBM, which could allow an attacker to trick a user into installing a malicious update.
2. The ROMM33 application does not properly parse user input before using it, which could allow an attacker to install a malicious update, or send messages with use of an application messaging vulnerability.
Thruway Electronic Control Unit (ECU)
The Thruway ECU is an embedded system that controls the operation of the WBM. The Thruway ECU runs a Linux operating system with a customized version of the uClibc library and communicates to other devices through CAN bus. This vulnerability allows outside parties to access the internal network of the WBM, which would allow them to infect it with malware. An attacker could also use this vulnerability to send fraudulent commands intended for other machines on the CAN bus or exfiltrate data from other machines on the CAN bus.
