CVSS v3.1 |
| 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. |
| Stack-based buffer overflow in Check Point VPN-1 Server 4.1 through 4.1 SP6 and Check Point SecuRemote/SecureClient 4.1 through 4.1 build 4200 allows remote attackers to execute arbitrary code via an ISAKMP packet with a large Certificate Request packet. |
| Heap-based buffer overflow in ASN.1 decoding library in Check Point VPN-1 products, when Aggressive Mode IKE is implemented, allows remote attackers to execute arbitrary code by initiating an IKE negotiation and then sending an IKE packet with malformed ASN.1 data. |
| Firewall-1 does not properly restrict access to LDAP attributes. |
| 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 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. |
| 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 4.0 and 4.1 allows remote attackers to cause a denial of service by sending a stream of invalid commands (such as binary zeros) to the SMTP Security Server proxy. |
| Checkpoint Firewall-1 with the RSH/REXEC setting enabled allows remote attackers to bypass access restrictions and connect to a RSH/REXEC client via malformed connection requests. |
| Check Point VPN-1/FireWall-1 4.1 and earlier allows remote attackers to bypass the directionality check via fragmented TCP connection requests or reopening closed TCP connection requests, aka "One-way Connection Enforcement Bypass." |
| Check Point VPN-1/FireWall-1 4.1 and earlier improperly retransmits encapsulated FWS packets, even if they do not come from a valid FWZ client, aka "Retransmission of Encapsulated Packets." |
| The inter-module authentication mechanism (fwa1) in Check Point VPN-1/FireWall-1 4.1 and earlier may allow remote attackers to conduct a denial of service, aka "Inter-module Communications Bypass." |
| The OPSEC communications authentication mechanism (fwn1) in Check Point VPN-1/FireWall-1 4.1 and earlier allows remote attackers to spoof connections, aka the "OPSEC Authentication Vulnerability." |
| The seed generation mechanism in the inter-module S/Key authentication mechanism in Check Point VPN-1/FireWall-1 4.1 and earlier allows remote attackers to bypass authentication via a brute force attack, aka "One-time (s/key) Password Authentication." |
| Check Point VPN-1/FireWall-1 4.1 and earlier allows remote attackers to redirect FTP connections to other servers ("FTP Bounce") via invalid FTP commands that are processed improperly by FireWall-1, aka "FTP Connection Enforcement Bypass." |
| Buffer overflow in Getkey in the protocol checker in the inter-module communication mechanism in Check Point VPN-1/FireWall-1 4.1 and earlier allows remote attackers to cause a denial of service. |
| The client authentication interface for Check Point Firewall-1 4.0 and earlier generates different error messages for invalid usernames versus invalid passwords, which allows remote attackers to identify valid usernames on the firewall. |
| Check Point Firewall-1 session agent 3.0 through 4.1 generates different error messages for invalid user names versus invalid passwords, which allows remote attackers to determine valid usernames and guess a password via a brute force attack. |
| Check Point FireWall-1 allows remote attackers to cause a denial of service (high CPU) via a flood of packets to port 264. |
| Check Point Firewall-1 allows remote attackers to cause a denial of service by sending a large number of malformed fragmented IP packets. |
