Vulnerabilities

The ventilator and the Service PC lack sufficient audit logging capabilities to allow for detection of malicious activity and subsequent forensic examination. An attacker with access to the ventilator and/or the Service PC could, without detection, make unauthorized changes to ventilator settings that result in unauthorized disclosure of information and/or have unintended impacts on device performance.

The software tools used by service personnel to test & calibrate the ventilator do not support user authentication. An attacker with access to the Service PC where the tools are installed could obtain diagnostic information through the test tool or manipulate the ventilator's settings and embedded software via the calibration tool, without having to authenticate to either tool. This could result in unauthorized disclosure of information and/or have unintended impacts on device settings and performance.

The ventilator's microcontroller lacks memory protection. An attacker could connect to the internal JTAG interface and read or write to flash memory using an off-the-shelf debugging tool, which could disrupt the function of the device and/or cause unauthorized information disclosure.

The ventilator does not perform proper file integrity checks when adopting firmware updates. This makes it possible for an attacker to force unauthorized changes to the device's configuration settings and/or compromise device functionality by pushing a compromised/illegitimate firmware file. This could disrupt the function of the device and/or cause unauthorized information disclosure.

The debug port on the ventilator's serial interface is enabled by default. This could allow an attacker to send and receive messages over the debug port (which are unencrypted; see 3.2.1) that result in unauthorized disclosure of information and/or have unintended impacts on device settings and performance.

The Clinician Password and Serial Number Clinician Password are hard-coded into the ventilator in plaintext form. This could allow an attacker to obtain the password off the ventilator and use it to gain unauthorized access to the device, with clinician privileges.

There is no limit on the number of failed login attempts permitted with the Clinician Password or the Serial Number Clinician Password. An attacker could execute a brute-force attack to gain unauthorized access to the ventilator, and then make changes to device settings that could disrupt the function of the device and/or result in unauthorized information disclosure.

Improper data protection on the ventilator's serial interface could allow an attacker to send and receive messages that result in unauthorized disclosure of information and/or have unintended impacts on device settings and performance.

In Baxter Connex health portal released before 8/30/2024, an improper access control vulnerability has been found that could allow an unauthenticated attacker to gain unauthorized access to Connex portal's database and/or modify content.

In Connex health portal released before8/30/2024, SQL injection vulnerabilities were found that could have allowed an unauthenticated attacker to gain unauthorized access to Connex portal's database.  An attacker could have submitted a crafted payload to Connex portal that could have resulted in modification and disclosure of database content and/or perform administrative operations including shutting down the database.

Insufficiently Protected Credentials vulnerability in Baxter Welch Allyn Configuration Tool may allow Remote Services with Stolen Credentials.This issue affects Welch Allyn Configuration Tool: versions 1.9.4.1 and prior.

Use of Default Cryptographic Key vulnerability in Baxter Welch Allyn Connex Spot Monitor may allow Configuration/Environment Manipulation.This issue affects Welch Allyn Connex Spot Monitor in all versions prior to 1.52.

The Baxter Spectrum WBM is susceptible to format string attacks via application messaging. An attacker could use this to read memory in the WBM to access sensitive information or cause a Denial of Service (DoS) on the WBM.

The Baxter Spectrum Wireless Battery Module (WBM) stores network credentials and PHI (only applicable to Spectrum IQ pumps using auto programming) in unencrypted form. An attacker with physical access to a device that hasn't had all data and settings erased may be able to extract sensitive information.

The Baxter Spectrum WBM (v16, v16D38) and Baxter Spectrum WBM (v17, v17D19, v20D29 to v20D32) when in superuser mode is susceptible to format string attacks via application messaging. An attacker could use this to read memory in the WBM to access sensitive information.

The Baxter Spectrum WBM does not perform mutual authentication with the gateway server host. This may allow an attacker to perform a man in the middle attack that modifies parameters making the network connection fail.

Baxter SIGMA Spectrum Infusion System version 6.05 (model 35700BAX) with wireless battery module (WBM) version 16 contains a hard-coded password, which provides access to basic biomedical information, limited device settings, and network configuration of the WBM, if connected. The hard-coded password may allow an attacker with physical access to the device to access management functions to make unauthorized configuration changes to biomedical settings such as turn on and off wireless connections and the phase-complete audible alarm that indicates the end of an infusion phase. Baxter has released a new version of the SIGMA Spectrum Infusion System, version 8, which incorporates hardware and software changes.

Baxter SIGMA Spectrum Infusion System version 6.05 (model 35700BAX) with wireless battery module (WBM) version 16 is remotely accessible via Port 22/SSH without authentication. A remote attacker may be able to make unauthorized configuration changes to the WBM, as well as issue commands to access account credentials and shared keys. Baxter asserts that this vulnerability only allows access to features and functionality on the WBM and that the SIGMA Spectrum infusion pump cannot be controlled from the WBM. Baxter has released a new version of the SIGMA Spectrum Infusion System, Version 8, which incorporates hardware and software changes.

An unauthenticated remote attacker may be able to execute commands to view wireless account credentials that are stored in cleartext on Baxter SIGMA Spectrum Infusion System version 6.05 (model 35700BAX) with wireless battery module (WBM) version 16, which may allow an attacker to gain access the host network. Baxter has released a new version of the SIGMA Spectrum Infusion System, Version 8, which incorporates hardware and software changes.

Baxter SIGMA Spectrum Infusion System version 6.05 (model 35700BAX) with wireless battery module (WBM) version 16 has a default account with hard-coded credentials used with the FTP protocol. Baxter asserts no files can be transferred to or from the WBM using this account. Baxter has released a new version of the SIGMA Spectrum Infusion System, Version 8, which incorporates hardware and software changes.
