CVE-2022-26388 is a medium-severity vulnerability that allows authentication abuse through the use of hard-coded passwords in various models of Baxter's Resting Electrocardiographs. This vulnerability affects the ELI 380, ELI 280/BUR280/MLBUR 280, ELI 250c/BUR 250c, and ELI 150c/BUR 150c/MLBUR 150c models across multiple versions. The vulnerability has a CVSS score of 6.4, indicating a medium level of risk.
The hard-coded password issue can lead to unauthorized access, posing serious risks to patient data and device integrity. Given the nature of the devices involved, these vulnerabilities may have a direct impact on patient safety and operational reliability.
The vulnerability is classified as a physical attack vector, meaning that an attacker would need physical access to the devices to exploit this flaw. However, the low attack complexity and lack of required privileges make this vulnerability particularly concerning. Organizations using these devices should prioritize remediation efforts.
As of now, there are no confirmed public exploits available, but the potential for exploitation underscores the importance of addressing this vulnerability. Organizations should take immediate action to assess their environments and mitigate risks associated with this vulnerability.
Vulnerability Details
The official description of CVE-2022-26388 states that it is a use of hard-coded password vulnerability that may allow authentication abuse. This issue affects the following ELI models and their corresponding versions:
- ELI 380 Resting Electrocardiograph: Versions 2.6.0 and prior
- ELI 280/BUR280/MLBUR 280 Resting Electrocardiograph: Versions 2.3.1 and prior
- ELI 250c/BUR 250c Resting Electrocardiograph: Versions 2.1.2 and prior
- ELI 150c/BUR 150c/MLBUR 150c Resting Electrocardiograph: Versions 2.2.0 and prior
The vulnerability is classified under CWE-259, indicating a weakness related to hard-coded credentials.
Technical Analysis
The root cause of this vulnerability is the use of hard-coded passwords in the firmware of the affected resting electrocardiographs. This leads to potential authentication abuse, as an attacker can gain unauthorized access to sensitive functionalities of the devices.
The attack vector is physical, meaning that an attacker must have physical access to the device to exploit this vulnerability. The attack complexity is low, and no privileges are required to execute the attack. User interaction is not necessary. The confidentiality and integrity impacts are both classified as high, indicating that sensitive data can be compromised, while the availability impact is low.
Risk & Impact Analysis
Risk to organizations includes the potential for unauthorized access to sensitive patient data and device functionalities. The blast radius of this vulnerability is significant, as it affects multiple models and versions of medical devices crucial for patient care.
Organizations using affected devices should assess the urgency of remediation based on the CVSS score of 6.4, which indicates a medium severity. Given the potential impact on patient safety, organizations should address this vulnerability in their priority patch cycle.
