CISA added five new vulnerabilities to its Known Exploited Vulnerabilities (KEV) Catalog, based on evidence of active exploitation.

• CVE-2021-32030 ASUS Routers Improper Authentication Vulnerability
• CVE-2023-39780 ASUS RT-AX55 Routers OS Command Injection Vulnerability
• CVE-2024-56145 Craft CMS Code Injection Vulnerability
• CVE-2025-3935 ConnectWise ScreenConnect Improper Authentication Vulnerability
• CVE-2025-35939 Craft CMS External Control of Assumed-Immutable Web Parameter 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 KEV 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 KEV Catalog vulnerabilities as part of their vulnerability management practice. CISA will continue to add vulnerabilities to the catalog that meet the specified criteria.

Please share your thoughts with us through our anonymous survey. We appreciate your feedback.

1. EXECUTIVE SUMMARY

• CVSS v4 9.3
• ATTENTION: Exploitable remotely/low attack complexity
• Vendor: Consilium Safety
• Equipment: CS5000 Fire Panel
• Vulnerabilities: Initialization of a Resource with an Insecure Default, Use of Hard-coded Credentials

2. RISK EVALUATION

Successful exploitation of these vulnerabilities could allow an attacker to gain high-level access to and remotely operate the device, potentially putting it into a non-functional state.

3. TECHNICAL DETAILS

3.1 AFFECTED PRODUCTS

The following Consilium Safety product is affected:

• CS5000 Fire Panel: All versions

3.2 VULNERABILITY OVERVIEW

3.2.1 INITIALIZATION OF A RESOURCE WITH AN INSECURE DEFAULT CWE-1188

The CS5000 Fire Panel is vulnerable due to a default account that exists on the panel. Even though it is possible to change this by SSHing into the device, it has remained unchanged on every installed system observed. This account is not root but holds high-level permissions that could severely impact the device's operation if exploited.

CVE-2025-41438 has been assigned to this vulnerability. A CVSS v3.1 base score of 9.8 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H).

A CVSS v4 score has also been calculated for CVE-2025-41438. A base score of 9.3 has been calculated; the CVSS vector string is (AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N).

3.2.2 USE OF HARD-CODED CREDENTIALS CWE-798

The CS5000 Fire Panel is vulnerable due to a hard-coded password that runs on a VNC server and is visible as a string in the binary responsible for running VNC. This password cannot be altered, allowing anyone with knowledge of it to gain remote access to the panel. Such access could enable an attacker to operate the panel remotely, potentially putting the fire panel into a non-functional state and causing serious safety issues.

CVE-2025-46352 has been assigned to this vulnerability. A CVSS v3.1 base score of 9.8 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H).

A CVSS v4 score has also been calculated for CVE-2025-46352. A base score of 9.3 has been calculated; the CVSS vector string is (AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N).

4. MITIGATIONS

Consilium Safety is aware of these vulnerabilities. Currently, no fixes are planned for the CS5000 Fire Panel.

Users wanting enhanced security features are advised to upgrade to Consilium Safety's newer line of fire panels. Specifically, products manufactured after July 1, 2024, incorporate more secure-by-design principles.

Users of the CS5000 Fire Panel are recommended to implement compensating countermeasures, such as physical security and access control restrictions for dedicated personnel.

More product safety information can be found on Consilium Safety's support webpage.

CISA recommends users take defensive measures to minimize the risk of exploitation of these vulnerabilities, such as:

• Minimize network exposure for all control system devices and/or systems, ensuring they are not accessible from the internet.
• Locate control system networks and remote devices behind firewalls and isolating them from business networks.
• When remote access is required, use more secure methods, such as Virtual Private Networks (VPNs), recognizing VPNs may have vulnerabilities and should be updated to the most current version available. Also recognize VPN is only as secure as the connected devices.

CISA reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures.

CISA also provides a section for control systems security recommended practices on the ICS webpage on cisa.gov/ics. Several CISA products detailing cyber defense best practices are available for reading and download, including Improving Industrial Control Systems Cybersecurity with Defense-in-Depth Strategies.

CISA encourages organizations to implement recommended cybersecurity strategies for proactive defense of ICS assets.

Additional mitigation guidance and recommended practices are publicly available on the ICS webpage at cisa.gov/ics in the technical information paper, ICS-TIP-12-146-01B--Targeted Cyber Intrusion Detection and Mitigation Strategies.

Organizations observing suspected malicious activity should follow established internal procedures and report findings to CISA for tracking and correlation against other incidents.

Today, CISA, in collaboration with the Australian Signals Directorate’s Australian Cyber Security Centre (ASD’s ACSC) and other international and U.S. partners, released new guidance for organizations seeking to procure Security Information and Event Management (SIEM) and Security Orchestration, Automation, and Response (SOAR) platforms.

This guidance includes the following three resources:

• Implementing SIEM and SOAR Platforms – Executive Guidance outlines how executives can enhance their organization’s cybersecurity framework by implementing these technologies to improve visibility into network activities, enabling swift detection and response to cyber threats.
• Implementing SIEM and SOAR Platforms – Practitioner Guidance focuses on how practitioners can quickly identify and respond to potential cybersecurity threats and leverage these technologies to streamline incident response processes by automating predefined actions based on detected anomalies.
• Priority Logs for SIEM Ingestion – Practitioner Guidance offers insights for prioritizing log ingestion into a SIEM, ensuring that critical data sources are effectively collected and analyzed to enhance threat detection and incident response capabilities tailored for organizations.

CISA encourages organizations to review this guidance and implement the recommended best practices to strengthen their cybersecurity. For access to the guidance documents, please visit CISA’s SIEM and SOAR Resource page.
