CVE-2024-24919: Check Point Security Gateway Information Disclosure

On May 28, 2024, Check Point published an advisory for CVE-2024-24919, a high-severity information disclosure vulnerability affecting Check Point Security Gateway devices configured with either the “IPSec VPN” or “Mobile Access” software blade.

On May 29, 2024, security firm mnemonic published a blog reporting that they have observed in-the-wild exploitation of CVE-2024-24919 since April 30, 2024, with threat actors leveraging the vulnerability to enumerate and extract password hashes for all local accounts, including accounts used to connect to Active Directory. They’ve also observed adversaries moving laterally and extracting the “ntds.dit” file from compromised customers’ Active Directory servers, within hours of an initial attack against a vulnerable Check Point Gateway.

Mitigation Guidance

According to the vendor advisory, the following products are vulnerable to CVE-2024-24919:

  • CloudGuard Network
  • Quantum Maestro
  • Quantum Scalable Chassis
  • Quantum Security Gateways
  • Quantum Spark Appliances

Check Point has advised that a Security Gateway is vulnerable if one of the following configuration is applied:

  • If the “IPSec VPN” blade has been enabled and the Security Gateway device is part of the “Remote Access” VPN community.
  • If the “Mobile Access” blade has been enabled.

Check Point has released hotfixes for Quantum Security Gateway, Quantum Maestro, Quantum Scalable Chassis, and Quantum Spark Appliances. We advise customers to refer to the Check Point advisory for the most current information on affected versions and hotfixes.

The vendor supplied hotfixes should be applied immediately. Rapid7 strongly recommends that Check Point Security Gateway customers examine their environments for signs of compromise and reset local account credentials in addition to applying vendor-provided fixes.

Check Point notes that exploit attempts their team has observed “focus on remote access scenarios with old local accounts with unrecommended password-only authentication.” The company recommends that customers check for local account usage, disable any unused local accounts, and add certificate-based authentication rather than password-only authentication. More information and recommendations on user and client authentication for remote access is available here.
