Overview

AI description

Automated description summarized from trusted sources.

CVE-2026-50751 is an authentication bypass vulnerability affecting Check Point Remote Access VPN, Mobile Access, and Spark Firewall products. This flaw arises from a logic flow weakness in the certificate validation process within the deprecated IKEv1 key exchange protocol. Exploitation of this vulnerability allows an unauthenticated remote attacker to bypass user authentication and establish a remote access VPN connection without requiring a valid user password. Successful exploitation requires specific conditions, including the enablement of Remote Access VPN or Mobile Access, active IKEv1 for remote access, and gateways that accept legacy Remote Access clients without demanding a machine certificate for connections. While a VPN session can be established, additional post-authentication activity is necessary to access internal resources or escalate privileges.

Description
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.
