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.

Check Point Quantum Security Gateways contain an unspecified information disclosure vulnerability. The vulnerability potentially allows an attacker to access information on Gateways connected to the internet, with IPSec VPN, Remote Access VPN or Mobile Access enabled. This issue affects several product lines from Check Point, including CloudGuard Network, Quantum Scalable Chassis, Quantum Security Gateways, and Quantum Spark Appliances.

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 flaw was found in the bash functionality that evaluates specially formatted environment variables passed to it from another environment. An attacker could use this feature to override or bypass restrictions to the environment to execute shell commands before restrictions have been applied. Certain services and applications allow remote unauthenticated attackers to provide environment variables, allowing them to exploit this issue.

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.

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 signaturealgorithms extension (where it was present in the initial ClientHello), but includes a signaturealgorithmscert 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).

GNU Bash through 4.3 bash43-025 processes trailing strings after certain malformed function definitions in the values of environment variables, which allows remote attackers to write to files or possibly have unknown other impact via a crafted environment, as demonstrated by vectors involving the ForceCommand feature in OpenSSH sshd, the modcgi and modcgid modules in the Apache HTTP Server, scripts executed by unspecified DHCP clients, and other situations in which setting the environment occurs across a privilege boundary from Bash execution. NOTE: this vulnerability exists because of an incomplete fix for CVE-2014-6271.

Check Point Session Authentication Agent allows remote attackers to obtain sensitive information (user credentials) via unspecified vectors.

Check Point R75.47 Security Gateway and Management Server does not properly enforce Anti-Spoofing when the routing table is modified and the "Get - Interfaces with Topology" action is performed, which allows attackers to bypass intended access restrictions.

Multiple unspecified vulnerabilities in Check Point Security Gateway 80 R71.x before R71.45 (730159141) and R75.20.x before R75.20.4 and 600 and 1100 appliances R75.20.x before R75.20.42 have unknown impact and attack vectors related to "important security fixes."

The OSPF implementation in Check Point Gaia OS R75.X and R76 and IPSO OS 6.2 R75.X and R76 does not consider the possibility of duplicate Link State ID values in Link State Advertisement (LSA) packets before performing operations on the LSA database, which allows remote attackers to cause a denial of service (routing disruption) or obtain sensitive packet information via a crafted LSA packet, a related issue to CVE-2013-0149.

Check Point Endpoint Security MI Server through R73 3.0.0 HFA2.5 does not configure X.509 certificate validation for client devices, which allows man-in-the-middle attackers to spoof SSL servers by presenting an arbitrary certificate during a session established by a client.

DISPUTED NOTE: this issue has been disputed by the vendor. Buffer overflow in the PKI Web Service in Check Point Firewall-1 PKI Web Service allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a long (1) Authorization or (2) Referer HTTP header to TCP port 18624. NOTE: the vendor has disputed this issue, stating "Check Point Security Alert Team has analyzed this report. We've tried to reproduce the attack on all VPN-1 versions from NG FP2 and above with and without HFAs. The issue was not reproduced. We have conducted a thorough analysis of the relevant code and verified that we are secure against this attack. We consider this attack to pose no risk to Check Point customers." In addition, the original researcher, whose reliability is unknown as of 20090407, also states that the issue "was discovered during a pen-test where the client would not allow further analysis."

Cross-site scripting (XSS) vulnerability in index.php in Check Point Connectra NGX R62 HFA01 allows remote attackers to inject arbitrary web script or HTML via the dir parameter. NOTE: the provenance of this information is unknown; the details are obtained solely from third party information.

Check Point VPN-1 R55, R65, and other versions, when Port Address Translation (PAT) is used, allows remote attackers to discover intranet IP addresses via a packet with a small TTL, which triggers an ICMPTIMXCEEDINTRANS (aka ICMP time exceeded in-transit) response containing an encapsulated IP packet with an intranet address, as demonstrated by a TCP packet to the firewall management server on port 18264.

Check Point FireWall-1 4.0 and 4.1 before SP5 allows remote attackers to obtain the IP addresses of internal interfaces via certain SecuRemote requests to TCP ports 256 or 264, which leaks the IP addresses in a reply packet.

Check Point FireWall-1 4.1 and Next Generation (NG), with UserAuth configured to proxy HTTP traffic only, allows remote attackers to pass unauthorized HTTPS, FTP and possibly other traffic through the firewall.

Check Point Firewall-1 allows remote attackers to cause a denial of service by sending a large number of malformed fragmented IP packets.

Firewall-1 3.0 and 4.0 leaks packets with private IP address information, which could allow remote attackers to determine the real IP address of the host that is making the connection.

Check Point Firewall-1 allows remote attackers to bypass port access restrictions on an FTP server by forcing it to send malicious packets that Firewall-1 misinterprets as a valid 227 response to a client's PASV attempt.

Firewall-1 does not properly filter script tags, which allows remote attackers to bypass the "Strip Script Tags" restriction by including an extra < in front of the SCRIPT tag.

Check Point Firewall-1 does not properly handle certain restricted keywords (e.g., Mail, auth, time) in user-defined objects, which could produce a rule with a default "ANY" address and result in access to more systems than intended by the administrator.

Firewall-1 does not properly restrict access to LDAP attributes.

Firewall-1 sets a long timeout for connections that begin with ACK or other packets except SYN, allowing an attacker to conduct a denial of service via a large number of connection attempts to unresponsive systems.

Check Point FireWall-1 can be subjected to a denial of service via UDP packets that are sent through VPN-1 to port 0 of a host.

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.

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.

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.

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.

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