Vulnerabilidades do Checkpoint Quantum Security Gateway

CVE-2026-85102 Crítica · 9.8 KEV Alta · 68 Exploit público CWE-295 09/09/2026

Check Point Multiple Products Improper Certificate Validation Vulnerability

Improper certificate trust validation during VPN negotiation in Check Point Quantum Security Gateway may allow an unauthenticated remote attacker to execute arbitrary code on the Gateway.

CVE-2026-50752 Alta · 7.4 CWE-295 08/06/2026

Certificate Validation Bypass in VPN Site-to-Site Connections Using IKEv1

A weakness in the certificate validation logic of the deprecated IKEv1 key exchange may allow an unauthenticated attacker positioned as a man-in-the-middle to bypass certificate validation in VPN site-to-site connections that use certificate-based authentication. Successful exploitation could allow interception or modification of traffic traversing the VPN tunnel.

CVE-2026-50751 Crítica · 9.3 KEV Urgente · 83 Exploit público Ransomware CWE-287 08/06/2026

Check Point Security Gateway Improper Authentication Vulnerability

A logic flow weakness in Remote Access and Mobile Access certificate validation in deprecated IKEv1 key exchange allows an unauthenticated remote attacker to bypass user authentication and establish a remote access VPN connection without a valid user password.

CVE-2026-48135 Média · 5.3 CWE-122 26/05/2026

HTTP service can incorrectly process malformed HTTP requests

A Check Point HTTP-based service can incorrectly handle malformed HTTP requests. The issue is related to HTTP request parsing and validation.

CVE-2026-48134 Média · 5.6 CWE-89 26/05/2026

SQL injection issue in UserCheck Portal when DLP Software Blade is active

When the DLP is active, the UserCheck Web Portal contains an input-handling issue in the UserChoice flow. Under specific conditions, an attacker who can access the UserCheck Ask page could attempt to manipulate the Security Gateway's stored DLP/UserCheck incident information. This could lead to disruptions such as loss of stored incident entries, incorrect handling of pending approvals, or resource impact if the issue is abused repeatedly. Exposure is reduced if the UserCheck Portal is not accessible from untrusted networks.

CVE-2026-48133 Alta · 7.5 CWE-98 26/05/2026

Identity Awareness Captive Portal - Unauthenticated Local File Inclusion

When the Identity Awareness blade is enabled with Browser-Based Authentication, an unauthenticated user may be able to read certain internal files on the Security Gateway.

CVE-2026-48132 Alta · 8.1 CWE-125 26/05/2026

VPN service may restart unexpectedly when processing IKE traffic over NAT-T 4500/UDP

The Security Gateway does not correctly validate a length value in certain IKE packets when NAT-T is used (4500/UDP). As a result, a specially crafted or malformed packet can cause the VPN processing service to terminate unexpectedly, leading to denial of service (temporary interruption of VPN negotiations/traffic).

CVE-2026-48131 Alta · 8.1 CWE-122 26/05/2026

VPND IKE Fragment Reassembly - Heap Out-of-Bounds Write via Sequence Number Zero

The VPN service may mishandle an unexpected IKE fragment value received on the IKE port 500/UDP during the early stage of a connection attempt. This can cause the service to terminate unexpectedly, resulting in denial of service (temporary disruption of VPN-related functionality).
