A directory traversal and file upload vulnerability allows an unauthenticated attacker to upload and execute arbitrary scripts on Check Point Management Server.
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.
A vulnerability in Check Point Gaia Portal allows an authenticated attacker with read-only Gaia Portal privileges to execute commands with root privileges.
An authentication bypass vulnerability in Check Point Security Management and Multi-Domain Security Management allows an unauthenticated remote attacker to execute administrative commands on the Management Server. Successful exploitation may also allow command execution on managed Security Gateways. Exploitation requires network access to the Management Server without firewall protection or a configuration that does not restrict Trusted Clients.
An authentication bypass vulnerability in the Check Point SmartConsole login process allows an unauthenticated remote attacker to obtain an application login token and use it to authenticate with full administrative privileges. Successful exploitation allows the attacker to modify security policies and security configurations. Remote exploitation requires internet access to the Management Server IP address and a configuration that does not restrict Trusted Clients. Check Point is aware that this vulnerability is being exploited and has affected a very small number of customers.
A local privilege escalation vulnerability exists in Check Point Identity Agent Full for Windows OS. An authenticated local user may be able to execute arbitrary code with SYSTEM privileges due to improper handling of executable resolution during the log collection process. Successful exploitation could allow an attacker to gain elevated privileges on the affected Windows endpoint.
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.
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.
When Compliance is enabled on Check Point Multi-Domain Management, an authenticated administrator with read-write access to one Management Domain (CMA) can modify stored metadata associated with Compliance Best Practices in another Management Domain, where the administrator has no access permissions, bypassing Role-Based Access Control (RBAC).
CVE-2026-48135 is a medium severity heap-based buffer overflow vulnerability in Check Point's Quantum Security Gateway. It arises from improper handling of malformed HTTP requests by an HTTP-based service, specifically related to HTTP request parsing and validation. The vulnerability affects multiple versions of the product, including R82.10 with Jumbo Hotfix Take 6 or below, R82 with Jumbo Hotfix Take 91 or below, R81.20 with Jumbo Hotfix Take 127 or below, and all releases from R81.10 and below. There is no confirmed patch or official remediation available at this time, and no known exploits have been reported in the wild.
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.
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.
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).
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).
An authenticated local user can obtain information that allows claiming security policy rules of another user due to sensitive information being printed in plaintext in Identity Agent for Terminal Services debug files.
An authenticated local user can obtain information that allows claiming security policy rules of another user due to sensitive information being accessible in the Windows Registry keys for Check Point Identity Agent running on a Terminal Server.
