CVE-2026-50751
CRITICAL KEV RANSOMWARECheck Point Quantum/Spark Gateways - Unauthenticated VPN Authentication Bypass
Title source: manualExploitation Summary
CVE-2026-50751 is actively exploited and listed in the CISA Known Exploited Vulnerabilities (KEV) catalog, added June 8, 2026, with confirmed use in ransomware campaigns. EIP tracks 6 public exploits from researchers including watchtowrlabs, fernstedt, fevar54.
AI-analyzed exploit summary This repository contains a functional exploit for CVE-2026-50751, a Check Point Remote Access VPN IKEv1 certificate-authentication bypass. The PoC demonstrates how an attacker can authenticate as a provisioned user without a valid certificate, private key, or password by exploiting a vulnerability in the iked service that skips certificate signature verification.
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.

This repository contains a functional exploit for CVE-2026-50751, a Check Point Remote Access VPN IKEv1 certificate-authentication bypass. The PoC demonstrates how an attacker can authenticate as a provisioned user without a valid certificate, private key, or password by exploiting a vulnerability in the iked service that skips certificate signature verification.
This repository contains a multi-threaded scanner for CVE-2026-50751, which detects if IKEv1 is enabled on Check Point Quantum Security Gateways. The tool sends minimal IKEv1 probes to target systems and checks for responses, but does not exploit the vulnerability.
This repository contains a functional Python exploit for CVE-2026-50751, which bypasses authentication in Check Point VPN gateways via a logic flaw in IKEv1 certificate validation. The exploit demonstrates the full attack chain from SA negotiation to VPN tunnel establishment.
This repository contains functional mitigation scripts for CVE-2026-50751, targeting Check Point VPN gateways. The scripts disable legacy client support and enforce IKEv2-only encryption to mitigate the vulnerability.
The repository contains a Python script that checks for the presence of IKEv1 on Check Point VPN gateways, which could indicate potential vulnerability to CVE-2026-50751. It does not exploit the vulnerability but scans for its presence.
The repository contains a functional IKEv1 authentication bypass exploit for Check Point gateways, but the cryptography module includes obfuscated malicious code that downloads and executes payloads from external URLs, indicating a trojanized exploit.
