CVE-2024-41724

Remediation/Mitigation Strategy for CVE-2024-41724

This document outlines a remediation and mitigation strategy for CVE-2024-41724, a vulnerability affecting the Gallagher Command Centre SALTO integration.

1. Vulnerability Description:

  • Vulnerability: Improper Certificate Validation (CWE-295)
  • Description: The Gallagher Command Centre SALTO integration fails to properly validate certificates, allowing an attacker to spoof the SALTO server. This could allow an attacker to intercept communications between the Gallagher Command Centre and the SALTO system, potentially leading to unauthorized access, data manipulation, or denial of service.

2. Severity:

  • CVSS Score: 8.7 (High)
  • CVSS Vector: AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N (Based on provided data)
    • AV:N: Attack Vector: Network - The vulnerability can be exploited over a network.
    • AC:L: Attack Complexity: Low - The vulnerability is easy to exploit.
    • PR:N: Privileges Required: None - No privileges are required to exploit the vulnerability.
    • UI:N: User Interaction: None - No user interaction is required to exploit the vulnerability.
    • S:U: Scope: Unchanged - An exploited vulnerability cannot affect resources beyond the security scope managed by the security authority of the vulnerable component.
    • C:H: Confidentiality: High - There is a high impact on confidentiality.
    • I:H: Integrity: High - There is a high impact on integrity.
    • A:N: Availability: None - There is no impact on availability.
  • Impact:
    • Confidentiality: Sensitive information exchanged between Gallagher Command Centre and SALTO may be compromised.
    • Integrity: Data exchanged between Gallagher Command Centre and SALTO may be modified, leading to incorrect access control decisions or other security issues.
    • Availability: Although the CVSS score indicates no impact on availability (A:N), successful spoofing could lead to denial of service if the attacker disrupts communication.

3. Affected Systems:

  • All versions of Gallagher Command Centre prior to 9.20.1043.

4. Known Exploits:

  • While specific exploit details are not included in the provided information, the nature of the vulnerability (improper certificate validation) suggests that common techniques like man-in-the-middle (MITM) attacks could be used to spoof the SALTO server. An attacker would need to be positioned on the network between the Gallagher Command Centre server and the SALTO server.

5. Remediation Strategy:

The primary remediation strategy is to upgrade to a patched version of Gallagher Command Centre.

  • Immediate Action: Upgrade to Gallagher Command Centre Version 9.20.1043 or later. This version contains the fix for CVE-2024-41724. Follow the Gallagher’s documented upgrade procedures.
  • Verification: After upgrading, verify that the SALTO integration is functioning correctly and that certificate validation is properly implemented. Consult Gallagher documentation or support for guidance on verifying correct certificate validation.

6. Mitigation Strategy (If immediate upgrade is not possible):

If an immediate upgrade is not possible, the following mitigation steps should be implemented:

  • Network Segmentation: Isolate the Gallagher Command Centre server and the SALTO server on a separate network segment with restricted access. This will limit the potential attack surface and make it more difficult for an attacker to intercept communication.
  • Network Monitoring: Implement network intrusion detection and prevention systems (IDS/IPS) to monitor traffic between the Gallagher Command Centre server and the SALTO server. Look for suspicious activity that might indicate a MITM attack or other exploitation attempts. Configure alerts for unusual network activity.
  • Mutual Authentication (if supported by SALTO): Explore enabling mutual TLS authentication if supported by both Gallagher Command Centre and SALTO. This requires both the client (Gallagher) and server (SALTO) to present certificates to each other, providing a stronger layer of security. Consult Gallagher and SALTO documentation for compatibility and configuration steps.
  • Disable Unnecessary Network Services: Minimize the services running on the Gallagher Command Centre server and the SALTO server to reduce the potential attack surface.
  • Review Access Controls: Ensure that access to the Gallagher Command Centre server and the SALTO server is restricted to only authorized personnel. Regularly review and update access control lists.
  • Implement a Web Application Firewall (WAF): While less directly relevant to the underlying vulnerability of certificate validation, a WAF in front of the Gallagher Command Centre application might offer some defense-in-depth against related attacks.

7. Long-Term Security Measures:

  • Regular Security Audits: Conduct regular security audits and penetration testing to identify and address potential vulnerabilities in the Gallagher Command Centre system and its integrations.
  • Vulnerability Management Program: Implement a vulnerability management program to proactively identify and address vulnerabilities in a timely manner. Subscribe to security advisories from Gallagher and other relevant vendors.
  • Security Awareness Training: Provide security awareness training to employees to educate them about common security threats and best practices.
  • Stay Updated: Keep the Gallagher Command Centre system and all associated components up-to-date with the latest security patches. Closely monitor security advisories released by Gallagher.

8. Communication:

  • Communicate this vulnerability and the remediation/mitigation steps to all relevant stakeholders, including IT staff, security personnel, and system administrators.

9. Documentation:

  • Document all remediation and mitigation steps taken, including the dates of implementation and any relevant configuration changes.

This remediation/mitigation strategy is based on the information provided and general security best practices. Consult with Gallagher support and your organization’s security team for specific guidance and implementation details.
