| This Multi-State Information Sharing and Analysis Center (MS-ISAC) Advisory is being provided to assist agencies and organizations in guarding against the persistent malicious actions of cybercriminals. NOTE: In an effort to reduce duplicate emails, if you currently receive cybersecurity advisories direct from the MS-ISAC, please let us know by responding to this email. |
| Multiple vulnerabilities have been discovered in Check Point products. Successful exploitation of the most severe of these vulnerabilities could allow an unauthenticated remote attacker to bypass authentication and gain unauthorized access to network resources. Depending on the privileges associated with the user, an attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than those who operate with administrative user rights. |
| Threat Intelligence |
| Check Point reports CVE-2026-50751 has been exploited in a limited number of cases in the wild. Additionally, they have attributed one case of exploitation to the Qilin ransomware operation. |

| Recommendations |
| Apply appropriate updates provided by Check Point to vulnerable systems immediately after appropriate testing. Apply the Principle of Least Privilege to all systems and services. Run all software as a non-privileged user (one without administrative privileges) to diminish the effects of a successful attack. Use vulnerability scanning to find potentially exploitable software vulnerabilities to remediate them. Architect sections of the network to isolate critical systems, functions, or resources. Use physical and logical segmentation to prevent access to potentially sensitive systems and information. Use a DMZ to contain any internet-facing services that should not be exposed from the internal network. Configure separate virtual private cloud (VPC) instances to isolate critical cloud systems. Use capabilities to detect and block conditions that may lead to or be indicative of a software exploit occurring. |
