Description

This security bulletin contains information about 6 vulnerabilities.

1) Input validation error (CVE-ID: CVE-2020-6962)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to insufficient validation of user-supplied input in the web-based system configuration utility. A remote attacker can obtain arbitrary code execution.

Note: This vulnerability affects the following versions of GE products:

• Clinical Information Center (CIC), Versions 4.X and 5.X
• CARESCAPE Central Station (CSCS), Versions 2.X
• B450, Version 2.X
  
• B650, Version 1.X
  
• B650, Version 2.X
  
• B850, Version 1.X
• B850, Version 2.X

2) Unprotected storage of credentials (CVE-ID: CVE-2020-6961)

CWE-ID: CWE-256 - Unprotected Storage of Credentials

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber

The vulnerability allows a remote attacker to gain access to other users' credentials.

The vulnerability exists due to application stored credentials in plain text in a configuration file on the system. A remote attacker can obtain access to the SSH private key in configuration files.

Note: This vulnerability affects the following versions of CIC and CSCS:

• Clinical Information Center (CIC), Versions 4.X and 5.X
• CARESCAPE Central Station (CSCS), Versions 2.X

3) Use of hard-coded credentials (CVE-ID: CVE-2020-6963)

CWE-ID: CWE-798 - Use of Hard-coded Credentials

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber

The vulnerability allows a remote attacker to gain full access to vulnerable system.

The vulnerability exists due to the affected products utilized hard coded SMB credentials. A remote unauthenticated attacker can access the affected system using the hard-coded credentials and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

Note: This vulnerability affects the following versions of CIC and CSCS:

• Clinical Information Center (CIC), Versions 4.X and 5.X
• CARESCAPE Central Station (CSCS), Versions 1.X

4) Missing Authentication for Critical Function (CVE-ID: CVE-2020-6964)

CWE-ID: CWE-306 - Missing Authentication for Critical Function

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber

The vulnerability allows a remote attacker to bypass authentication on an affected device.

 The vulnerability exists due to an issue in the integrated service for keyboard switching of the affected devices. A remote attacker can obtain remote keyboard input access without authentication over the network.

Note: This vulnerability affects the following versions of GE products:

• Clinical Information Center (CIC), Versions 4.X and 5.X
• CARESCAPE Central Station (CSCS), Versions 2.X

5) Arbitrary file upload (CVE-ID: CVE-2020-6965)

CWE-ID: CWE-434 - Unrestricted Upload of File with Dangerous Type

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Green

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to insufficient validation of file uploads in the software update mechanism. A remote authenticated attacker can upload arbitrary files on the system through a crafted update package.

Note: This vulnerability affects the following versions of GE products:

• Clinical Information Center (CIC), Versions 4.X and 5.X
• CARESCAPE Central Station (CSCS), Versions 1.X
• B450, Version 2.X
• B650, Version 1.X
• B650, Version 2.X
• B850, Version 1.X
• B850, Version 2.X

6) Inadequate Encryption Strength (CVE-ID: CVE-2020-6966)

CWE-ID: CWE-326 - Inadequate Encryption Strength

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber

The vulnerability allows a remote attacker to execute arbitrary code on the target device.

The vulnerability exists due to the affected products utilize a weak encryption scheme for remote desktop control. A remote attacker can execute arbitrary code on devices on the network.

Note: This vulnerability affects the following versions of CIC and CSCS:

• Clinical Information Center (CIC), Versions 4.X and 5.X
• CARESCAPE Central Station (CSCS), Versions 1.X
