Local privilege escalation to root in the DynamicCLI daemon via local world-writable control socket

The Gaia OS DynamicCLI daemon runs as root and listens on a world-writable local socket (/tmp/dynamic_socket) without authenticating connecting processes. An authenticated local user can send a command to the socket and have it executed as root.

Input Validation Vulnerability in Gaia Portal backend handlers allows privilege escalation by an authenticated user

An input and authorization validation vulnerability in Gaia Portal backend handlers could allow an authenticated, non-administrative user to perform privileged operations that should be restricted to administrators.

NULL pointer deref in signature_algorithms processing

An OpenSSL TLS server may crash if sent a maliciously crafted renegotiation ClientHello message from a client. If a TLSv1.2 renegotiation ClientHello omits the signature_algorithms extension (where it was present in the initial ClientHello), but includes a signature_algorithms_cert extension then a NULL pointer dereference will result, leading to a crash and a denial of service attack. A server is only vulnerable if it has TLSv1.2 and renegotiation enabled (which is the default configuration). OpenSSL TLS clients are not impacted by this issue. All OpenSSL 1.1.1 versions are affected by this issue. Users of these versions should upgrade to OpenSSL 1.1.1k. OpenSSL 1.0.2 is not impacted by this issue. Fixed in OpenSSL 1.1.1k (Affected 1.1.1-1.1.1j).

Improper Certificate Validation in Quantum Security Gateway

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.

Heap-based Buffer Overflow in VPN Certificate ASN.1 Decoding

A heap-based buffer overflow in VPN certificate ASN.1 decoding may allow an unauthenticated remote attacker to execute arbitrary code on Check Point Quantum Security Management and Quantum Security Gateway systems.

Local Privilege Escalation in Gaia Portal

A vulnerability in Check Point Gaia Portal allows an authenticated attacker with read-only Gaia Portal privileges to execute commands with root privileges.

User Authentication Bypass in VPN Remote Access and Mobile Access

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.

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.

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.

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.

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).

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.

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).

Information disclosure

Potentially allowing an attacker to read certain information on Check Point Security Gateways once connected to the internet and enabled with remote Access VPN or Mobile Access Software Blades. A Security fix that mitigates this vulnerability is available.

Authenticated Gaia users can inject code or commands by global variables through special HTTP requests. A Security fix that mitigates this vulnerability is available.

The Check Point Gaia Portal's GUI Clients allowed authenticated administrators with permission for the GUI Clients settings to inject a command that would run on the Gaia OS.
