Vulnerabilities

Check Point SmartConsole, the administrative client used to manage Quantum Security Management and Multi-Domain Security Management, contains an authentication bypass (CWE-287) in its login process that allows an unauthenticated remote attacker to obtain an application login token and authenticate with full administrative privileges. Exploitation is possible when the Management Server IP address is reachable from the internet and the configuration does not restrict Trusted Clients. A successful attacker can modify security policies and security configurations, effectively taking control of firewall management. Any organization running an internet-exposed Check Point management server without Trusted Client restrictions is affected, though Check Point reports exploitation has impacted only a very small number of customers. The flaw was added to CISA's KEV on 2026-07-22, is actively exploited, and press reports indicate public proof-of-concept code has been released.

Do: Apply the fix released in Check Point's advisory for CVE-2026-16232 by updating SmartConsole and the associated Quantum/MDS management software; no fixed version numbers were provided in this data, so confirm them against the vendor bulletin. As an interim mitigation, restrict internet access to the Management Server IP address and configure Trusted Clients so SmartConsole connections are accepted only from known administrator addresses. Review management logs for unexpected logins, unauthenticated token issuance, or unfamiliar administrator sessions, and complete remediation per CISA BOD 26-04 given the KEV listing.

Check Point has disclosed CVE-2026-50751, a critical (CVSS 9.3) improper authentication flaw (CWE-287) in the certificate validation logic for Remote Access and Mobile Access VPN when the deprecated IKEv1 key exchange is used. An unauthenticated remote attacker can exploit this logic flow weakness during IKEv1 negotiation to bypass user authentication entirely. Successful exploitation lets the attacker establish a remote access VPN connection without a valid user password, gaining access to the organization's internal network resources (high confidentiality impact per the CVSS score). Any organization running a Check Point Security Gateway on Gaia OS or Gaia Embedded with IKEv1-based Remote Access/Mobile Access configured is affected; specific affected and fixed versions are in Check Point's advisory. The flaw is being exploited in the wild — it was added to CISA's Known Exploited Vulnerabilities catalog on 2026-06-08 with known ransomware use and an EPSS of 83.8% — and it was disclosed alongside other critical Check Point VPN certificate flaws per recent headlines.

Do: Upgrade affected Security Gateways to the fixed releases identified in Check Point's advisory (version numbers are not specified in the source data), prioritizing internet-facing VPN gateways; as an interim mitigation, move Remote Access/Mobile Access clients to IKEv2 or disable IKEv1. Review VPN authentication logs for sessions established without valid credentials, given known in-the-wild and ransomware exploitation. Federal agencies must apply mitigations per BOD 22-01, and defenders should beware of fake 'public PoC' repositories spreading malware (ChocoPoC RAT), since no legitimate public PoC is known.

Log files uploaded during troubleshooting by the Harmony SASE agent may have been accessible to unauthorized parties.

Lack of TLS validation when downloading a CSV file including mapping from IPs to countries used ONLY for displaying country flags in logs

The Mobile Access Portal's File Share application is vulnerable to a directory traversal attack, allowing an authenticated, malicious end-user (authorized to at least one File Share application) to list the file names of 'nobody'-accessible directories on the Mobile Access gateway.

Credentials are not cleared from memory after being used. A user with Administrator permissions can execute memory dump for SmartConsole process and fetch them.

Untrusted DLLs in the installer's directory may be loaded and executed, leading to potentially arbitrary code execution with the installer's privileges (admin).

For an authenticated end-user the portal may run a script while attempting to display a directory or some file's properties.

In rare scenarios, the cpca process on the Security Management Server / Domain Management Server may exit unexpectedly, creating a core dump file. When the cpca process is down, VPN and SIC connectivity issues may occur if the CRL is not present in the Security Gateway's CRL cache.

Check Point ZoneAlarm Extreme Security Link Following Local Privilege Escalation Vulnerability. This vulnerability allows local attackers to escalate privileges on affected installations of Check Point ZoneAlarm Extreme Security. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the Forensic Recorder service. By creating a symbolic link, an attacker can abuse the service to overwrite arbitrary files. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of SYSTEM. Was ZDI-CAN-21677.

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

Check Point Quantum Security Gateways contain an information disclosure flaw (CWE-200) that can expose information stored on the appliance to unauthorized parties. It is triggered when an attacker targets a gateway connected to the internet with IPSec VPN, Remote Access VPN, or Mobile Access enabled, sending crafted requests to the exposed VPN services. A successful attacker gains unauthorized access to information on the gateway, and CISA notes known use of this flaw in ransomware campaigns. The issue spans multiple Check Point product lines: CloudGuard Network, Quantum Scalable Chassis, Quantum Security Gateways, and Quantum Spark Appliances. Exploitation is confirmed in the wild: the flaw was added to CISA's KEV catalog on 2024-05-30 with ransomware use listed, and EPSS assigns a 100% probability of exploitation within 30 days, though no public proof-of-concept is known.

Do: Apply the hotfix Check Point distributes per its advisory (SK170863) to all internet-facing gateways running IPSec VPN, Remote Access VPN, or Mobile Access; this is also the CISA KEV required action. Where the hotfix cannot be applied immediately, restrict or disable the Remote Access VPN and Mobile Access software blades as an interim mitigation. Review gateway and VPN logs for signs of exploitation and prioritize remediation given confirmed ransomware use.

A local privilege escalation vulnerability has been identified in Harmony Endpoint Security Client for Windows versions E88.10 and below. To exploit this vulnerability, an attacker must first obtain the ability to execute local privileged code on the target system.

A local attacker can erscalate privileges on affected Check Point ZoneAlarm ExtremeSecurity NextGen, Identity Agent for Windows, and Identity Agent for Windows Terminal Server. To exploit this vulnerability, an attacker must first obtain the ability to execute local privileged code on the target system.

Local privilege escalation in Check Point Endpoint Security Client (version E87.30) via crafted OpenSSL configuration file

The IPsec VPN blade has a dedicated portal for downloading and connecting through SSL Network Extender (SNX). If the portal is configured for username/password authentication, it is vulnerable to a brute-force attack on usernames and passwords.

Check Point ZoneAlarm Extreme Security before 15.8.211.19229 allows local users to escalate privileges. This occurs because of weak permissions for the %PROGRAMDATA%\CheckPoint\ZoneAlarm\Data\Updates directory, and a self-protection driver bypass that allows creation of a junction directory. This can be leveraged to perform an arbitrary file move as NT AUTHORITY\SYSTEM.

A potential memory corruption issue was found in Capsule Workspace Android app (running on GrapheneOS). This could result in application crashing but could not be used to gather any sensitive information.

Check Point Endpoint before version E86.50 failed to protect against specific registry change which allowed to disable endpoint protection by a local administrator.

Check Point Endpoint Security Client for Windows versions earlier than E86.40 copy files for forensics reports from a directory with low privileges. An attacker can replace those files with malicious or linked content, such as exploiting CVE-2020-0896 on unpatched systems or using symbolic links.

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.

Check Point ZoneAlarm before version 15.8.200.19118 allows a local actor to escalate privileges during the upgrade process. In addition, weak permissions in the ProgramData\CheckPoint\ZoneAlarm\Data\Updates directory allow a local attacker the ability to execute an arbitrary file write, leading to execution of code as local system, in ZoneAlarm versions before v15.8.211.192119

Users have access to the directory where the installation repair occurs. Since the MS Installer allows regular users to run the repair, an attacker can initiate the installation repair and place a specially crafted EXE in the repair folder which runs with the Check Point Remote Access Client privileges.

The Harmony Browse and the SandBlast Agent for Browsers installers must have admin privileges to execute some steps during the installation. Because the MS Installer allows regular users to repair their installation, an attacker running an installer before 90.08.7405 can start the installation repair and place a specially crafted binary in the repair folder, which runs with the admin privileges.

Mobile Access Portal Native Applications who's path is defined by the administrator with environment variables may run applications from other locations by the Mobile Access Portal Agent.

SSL Network Extender Client for Linux before build 800008302 reveals part of the contents of the configuration file supplied, which allows partially disclosing files to which the user did not have access.

A denial of service vulnerability was reported in Check Point Identity Agent before R81.018.0000, which could allow low privileged users to overwrite protected system files.

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).

Check Point SmartConsole before R80.10 Build 185, R80.20 Build 119, R80.30 before Build 94, R80.40 before Build 415, and R81 before Build 548 were vulnerable to a possible local privilege escalation due to running executables from a directory with write access to all authenticated users.

Check Point Endpoint Security Client for Windows before version E84.20 allows write access to the directory from which the installation repair takes place. Since the MS Installer allows regular users to run the repair, an attacker can initiate the installation repair and place a specially crafted DLL in the repair folder which will run with the Endpoint client’s privileges.

Check Point Endpoint Security for Windows before E84.10 can reach denial of service during clean install of the client which will prevent the storage of service log files in non-standard locations.

Check Point Endpoint Security Client for Windows, with Anti-Bot or Threat Emulation blades installed, before version E83.20, tries to load a non-existent DLL during a query for the Domain Name. An attacker with administrator privileges can leverage this to gain code execution within a Check Point Software Technologies signed binary, where under certain circumstances may cause the client to terminate.

Check Point ZoneAlarm before version 15.8.139.18543 allows a local actor to escalate privileges while restoring files in Anti-Ransomware.

Check Point Security Management's Internal CA web management before Jumbo HFAs R80.10 Take 278, R80.20 Take 160, R80.30 Take 210, and R80.40 Take 38, can be manipulated to run commands as a high privileged user or crash, due to weak input validation on inputs by a trusted management administrator.

ZoneAlarm Anti-Ransomware before version 1.0.713 copies files for the report from a directory with low privileges. A sophisticated timed attacker can replace those files with malicious or linked content, such as exploiting CVE-2020-0896 on unpatched systems or using symbolic links. This allows an unprivileged user to enable escalation of privilege via local access.

ZoneAlarm Firewall and Antivirus products before version 15.8.109.18436 allow an attacker who already has access to the system to execute code at elevated privileges through a combination of file permission manipulation and exploitation of Windows CVE-2020-00896 on unpatched systems.

A denial of service vulnerability was reported in Check Point Endpoint Security Client for Windows before E82.10, that could allow service log file to be written to non-standard locations.

In a rare scenario, Check Point R80.30 Security Gateway before JHF Take 50 managed by Check Point R80.30 Management crashes with a unique configuration of enhanced logging.

Check Point Endpoint Security Initial Client for Windows before version E81.30 tries to load a DLL placed in any PATH location on a clean image without Endpoint Client installed. An attacker can leverage this to gain LPE using a specially crafted DLL placed in any PATH location accessible with write permissions to the user.

Check Point Endpoint Security Client for Windows, with the VPN blade, before version E80.83, starts a process without using quotes in the path. This can cause loading of a previously placed executable with a name similar to the parts of the path, instead of the intended one.

Check Point Endpoint Security Client for Windows, with Anti-Malware blade installed, before version E81.00, tries to load a non-existent DLL during an update initiated by the UI. An attacker with administrator privileges can leverage this to gain code execution within a Check Point Software Technologies signed binary, where under certain circumstances may cause the client to terminate.

A local attacker can create a hard-link between a file to which the Check Point Endpoint Security client for Windows before E80.96 writes and another BAT file, then by impersonating the WPAD server, the attacker can write BAT commands into that file that will later be run by the user or the system.

A hard-link created from log file archive of Check Point ZoneAlarm up to 15.4.062 or Check Point Endpoint Security client for Windows before E80.96 to any file on the system will get its permission changed so that all users can access that linked file. Doing this on files with limited access gains the local attacker higher privileges to the file.

A hard-link created from the log file of Check Point ZoneAlarm up to 15.4.062 to any file on the system will get its permission changed so that all users can access that linked file. Doing this on files with limited access gains the local attacker higher privileges to the file.

Check Point IKEv2 IPsec VPN up to R80.30, in some less common conditions, may allow an attacker with knowledge of the internal configuration and setup to successfully connect to a site-to-site VPN server.
