3.4 RESEARCHER

An anonymous researcher working with Trend Micro’s Zero Day Initiative reported these vulnerabilities to CISA.

4. MITIGATIONS

Schneider Electric has provided a fix to these vulnerabilities and recommends updating the software to v1.16.4. After installation, it is recommended to reboot the system and verify the version number reflects the new version.

If users choose not to apply the remediation provided, they should immediately apply the following mitigation to reduce the risk of exploit:

Block TCP Port 20023 to SpaceLogic C-Bus Toolkit by using the rules in the PC firewall.

By doing this, the vulnerable commands could not then be used to compromise the PC by an external entity as the connection and ultimately the command will not be accepted by SpaceLogic C-Bus Toolkit.

For more information, refer to Schneider Electric’s Security Bulletin SEVD-2023-283-1

Schneider Electric strongly recommends the following industry cybersecurity best practices.

Locate control and safety system networks and remote devices behind firewalls and isolate them from the business network.
Install physical controls so no unauthorized personnel can access your industrial control and safety systems, components, peripheral equipment, and networks.
Place all controllers in locked cabinets and never leave them in the “Program” mode.
Never connect programming software to any network other than the network intended for that device.
Scan all methods of mobile data exchange with the isolated network such as CDs, USB drives, etc., before use in the terminals or any node connected to these networks.
Never allow mobile devices that have connected to any other network besides the intended network to connect to the safety or control networks without proper sanitation.
Minimize network exposure for all control system devices and systems and ensure that they are not accessible from the Internet.
When remote access is required, use secure methods, such as virtual private networks (VPNs). Recognize that VPNs may have vulnerabilities and should be updated to the most current version available. Also, understand that VPNs are only as secure as the connected devices.

1. EXECUTIVE SUMMARY

CVSS v3 8.8
ATTENTION: Exploitable remotely/low attack complexity
Vendor: Red Lion
Equipment: FlexEdge Gateway, DA50A, DA70A running Crimson
Vulnerability: Improper Neutralization of Null Byte or NUL Character

2. RISK EVALUATION

Successful exploitation of this vulnerability could allow an attacker to truncate passwords configured by the Crimson configuration tool which could create weaker than intended credentials.

3. TECHNICAL DETAILS

3.1 AFFECTED PRODUCTS

The following Red Lion products are affected:

Crimson: v3.2.0053.18 or prior

3.2 Vulnerability Overview

3.2.1 IMPROPER NEUTRALIZATION OF NULL BYTE OR NUL CHARACTER CWE-158

The Crimson 3.2 Windows-based configuration tool allows users with administrative access to define new passwords for users and to download the resulting security configuration to a device. If such a password contains the percent (%) character, invalid values will be included, potentially truncating the string if a NUL is encountered. If the simplified password is not detected by the administrator, the device might be left in a vulnerable state as a result of more-easily compromised credentials. Note that passwords entered via the Crimson system web server do not suffer from this vulnerability.

CVE-2023-5719 has been assigned to this vulnerability. A CVSS v3 base score of 8.8 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H).

4. MITIGATIONS

Red Lion recommends updating the Crimson configuration tool to version 3.2.0063 or later by using the automatic update feature or visiting the Red Lion website.

Any existing or new accounts created should refrain from using the percent (%) character in the configured password in versions 3.2.0053.18 or below.
