1. EXECUTIVE SUMMARY

• CVSS v3 10.0
• ATTENTION: Exploitable remotely/low attack complexity
• Vendor: Schneider Electric
• Equipment: Galaxy VS, Galaxy VL, Galaxy VXL
• Vulnerability: Missing Authentication for Critical Function

2. RISK EVALUATION

Successful exploitation of this vulnerability could allow an attacker to perform unauthenticated remote code execution.

3. TECHNICAL DETAILS

3.1 AFFECTED PRODUCTS

The following versions of Schneider Electric products are affected:

• Galaxy VS: All versions
• Galaxy VL: All versions
• Galaxy VXL: All versions

3.2 VULNERABILITY OVERVIEW

3.2.1 MISSING AUTHENTICATION FOR CRITICAL FUNCTION CWE-306

Erlang/OTP is a set of libraries for the Erlang programming language. Prior to versions OTP-27.3.3, OTP-26.2.5.11, and OTP-25.3.2.20, a SSH server may allow an attacker to perform unauthenticated remote code execution (RCE). By exploiting a flaw in SSH protocol message handling, a malicious actor could gain unauthorized access to affected systems and execute arbitrary commands without valid credentials. This issue is patched in versions OTP-27.3.3, OTP-26.2.5.11, and OTP-25.3.2.20. A temporary workaround involves disabling the SSH server or to prevent access via firewall rules.

CVE-2025-32433 has been assigned to this vulnerability. A CVSS v3.1 base score of 10.0 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H).

3.3 BACKGROUND

4. MITIGATIONS

Schneider Electric is establishing a remediation plan for all future versions of Galaxy VS, Galaxy VL, and Galaxy VXL that will include a fix for this vulnerability. Schneider Electric will update this document when the remediation is available. Until then, users should immediately apply the following mitigations to reduce the risk of exploit:

• Log on to the NMC4 via the Web Interface. Once logged into the system, navigate to the Console settings page from the menu bar by selecting Configuration -> Network -> Console -> Access
• From the Console setting screen, uncheck the enable SSH/SFTP/SCP check box -> Click Apply
• As an alternative, setup network segmentation and implement a firewall to block all unauthorized access to SSH port 22/TCP.
• If assistance is needed applying the above mitigation, please contact our technical support team: https://www.se.com/ww/en/work/support/

To learn more, Schneider Electric recommends reviewing the Network Management Card 4 Security Handbook for specific actions available here to secure your devices further: https://www.se.com/us/en/download/document/SPD_CCON-B8EJSJ_EN/

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.

5. UPDATE HISTORY

• May 20, 2025: Initial Publication.

A local attacker or untrusted component running within a Go application could bypass directory confinement by accessing the parent directory of a restricted os.DirFS root using a "../" path.

A remote attacker that is able to load a specially crafted font file is able to execute arbitrary code on the affected host.

A remote attacker can exploit inefficient HTML tag parsing in Django’s strip_tags() function to cause excessive CPU usage, leading to a denial of service. This may affect applications that use the striptags template filter to sanitize user-controlled input, making them vulnerable to slowdown or unresponsiveness when handling specially crafted HTML content.

A remote attacker can craft a malicious hostname to execute arbitrary commands on a system using dbclient if the hostname is passed without proper sanitization.

CISA has added six new vulnerabilities to its Known Exploited Vulnerabilities Catalog, based on evidence of active exploitation. 

• CVE-2025-4427 Ivanti Endpoint Manager Mobile (EPMM) Authentication Bypass Vulnerability
• CVE-2025-4428 Ivanti Endpoint Manager Mobile (EPMM) Code Injection Vulnerability
• CVE-2024-11182 MDaemon Email Server Cross-Site Scripting (XSS) Vulnerability

• CVE-2024-27443 Synacor Zimbra Collaboration Suite (ZCS) Cross-Site Scripting (XSS) Vulnerability
• CVE-2023-38950 ZKTeco BioTime Path Traversal Vulnerability

These types of vulnerabilities are frequent attack vectors for malicious cyber actors and pose significant risks to the federal enterprise. 

Binding Operational Directive (BOD) 22-01: Reducing the Significant Risk of Known Exploited Vulnerabilities established the Known Exploited Vulnerabilities Catalog as a living list of known Common Vulnerabilities and Exposures (CVEs) that carry significant risk to the federal enterprise. BOD 22-01 requires Federal Civilian Executive Branch (FCEB) agencies to remediate identified vulnerabilities by the due date to protect FCEB networks against active threats. See the BOD 22-01 Fact Sheet for more information. 

Although BOD 22-01 only applies to FCEB agencies, CISA strongly urges all organizations to reduce their exposure to cyberattacks by prioritizing timely remediation of Catalog vulnerabilities as part of their vulnerability management practice. CISA will continue to add vulnerabilities to the catalog that meet the specified criteria.
