CVE-2024-24919 is a recently disclosed vulnerability affecting Check Point Remote Access VPN products, which provide secure remote connectivity to enterprise networks. This vulnerability targets public-facing VPN services, potentially allowing attackers to exploit weaknesses in the remote access mechanisms. Although the advisory from CIRCL indicates active exploitation, no confirmed exploits have been observed in the wild, and the severity is currently rated as low. The vulnerability maps to MITRE ATT&CK techniques T1190 (exploit public-facing application) and T1133 (external remote services), indicating attackers may leverage this flaw to gain unauthorized access or escalate privileges via the VPN. The lack of detailed technical information and absence of a CVSS score suggest that the vulnerability might be complex or limited in scope, but the 50% certainty of exploitation implies a moderate threat level. Check Point VPNs are widely used in European enterprises and critical infrastructure sectors, making this vulnerability particularly relevant. The threat primarily affects confidentiality and integrity by potentially allowing unauthorized access to sensitive internal resources. The advisory recommends immediate mitigation steps such as applying vendor patches once available, restricting VPN access to trusted IPs, and enhancing network monitoring to detect suspicious activities related to VPN usage. Given the active exploitation reports, organizations should prioritize these mitigations to reduce risk exposure. The threat level is currently moderate, but could escalate if exploitation becomes widespread or more technical details emerge.

For European organizations, the exploitation of CVE-2024-24919 could lead to unauthorized remote access to internal networks via compromised VPN services. This can result in data breaches, lateral movement within networks, and potential disruption of critical services, especially in sectors such as finance, energy, healthcare, and government. Confidentiality and integrity of sensitive data are at risk, with possible exposure of intellectual property and personal data protected under GDPR. Availability impact is likely limited unless attackers leverage access to launch further attacks such as ransomware. The moderate ease of exploitation and absence of required user interaction increase the risk profile. Organizations relying heavily on Check Point Remote Access VPN for secure remote connectivity are particularly vulnerable. The threat also raises compliance concerns for European entities obligated to maintain robust cybersecurity measures. Failure to mitigate could lead to reputational damage and regulatory penalties. The active exploitation reports heighten urgency for European organizations to assess and remediate their VPN deployments promptly.

1. Apply vendor patches immediately once released by Check Point to address CVE-2024-24919. 2. Restrict VPN access by implementing IP whitelisting or geofencing to limit connections to trusted sources. 3. Enforce multi-factor authentication (MFA) on all VPN accounts to reduce risk of credential compromise. 4. Enhance network monitoring and logging specifically for VPN access patterns, looking for anomalies such as unusual login times, multiple failed attempts, or connections from unexpected locations. 5. Conduct regular vulnerability scanning and penetration testing focused on VPN infrastructure to identify and remediate weaknesses. 6. Segment VPN access to limit lateral movement in case of compromise, ensuring least privilege principles are applied. 7. Educate IT and security teams about this vulnerability and encourage prompt incident response readiness. 8. Review and update VPN configurations to disable legacy or insecure protocols and enforce strong encryption standards. 9. Collaborate with Check Point support and threat intelligence providers to stay informed on emerging exploit techniques and patches. 10. Consider temporary reduction of VPN exposure by disabling unused or non-critical VPN endpoints until mitigations are in place.
