| CVE | Summary | Source | Max CVSS | EPSS % | Published | Updated |
|---|---|---|---|---|---|---|
| CVE-2006-3906 | Internet Key Exchange (IKE) version 1 protocol, as implemented on Cisco IOS, VPN 3000 Concentrators, and PIX firewalls, allows remote attackers to cause a denial of service (resource exhaustion) via a flood of IKE Phase-1 packets that exceed the session expiration rate. NOTE: it has been argued that this is due to a design weakness of the IKE version 1 protocol, in which case other vendors and implementations would also be affected. | [email protected] | 5.0 | 4.28% | 2006-07-27 | 2026-04-16 |
| CVE-2006-0515 | Cisco PIX/ASA 7.1.x before 7.1(2) and 7.0.x before 7.0(5), PIX 6.3.x before 6.3.5(112), and FWSM 2.3.x before 2.3(4) and 3.x before 3.1(7), when used with Websense/N2H2, allows remote attackers to bypass HTTP access restrictions by splitting the GET method of an HTTP request into multiple packets, which prevents the request from being sent to Websense for inspection, aka bugs CSCsc67612, CSCsc68472, and CSCsd81734. | [email protected] | 7.5 | 5.94% | 2006-05-09 | 2026-04-16 |
| CVE-2005-4499 | The Downloadable RADIUS ACLs feature in Cisco PIX and VPN 3000 concentrators, when creating an ACL on the Cisco Secure Access Control Server (CS ACS), generates a random internal name for an ACL that is also used as a hidden user name and password, which allows remote attackers to gain privileges by sniffing the username from the cleartext portion of a RADIUS session, then using the password to log in to another device that uses CS ACS. | [email protected] | 7.5 | 1.90% | 2005-12-22 | 2026-04-16 |
| CVE-2005-3669 | Multiple unspecified vulnerabilities in the Internet Key Exchange version 1 (IKEv1) implementation in multiple Cisco products allow remote attackers to cause a denial of service (device reset) via certain malformed IKE packets, as demonstrated by the PROTOS ISAKMP Test Suite for IKEv1. NOTE: due to the lack of details in the Cisco advisory, it is unclear which of CVE-2005-3666, CVE-2005-3667, and/or CVE-2005-3668 this issue applies to. | [email protected] | 5.0 | 9.46% | 2005-11-18 | 2026-04-16 |
| CVE-2004-0112 | The SSL/TLS handshaking code in OpenSSL 0.9.7a, 0.9.7b, and 0.9.7c, when using Kerberos ciphersuites, does not properly check the length of Kerberos tickets during a handshake, which allows remote attackers to cause a denial of service (crash) via a crafted SSL/TLS handshake that causes an out-of-bounds read. | [email protected] | 5.0 | 0.92% | 2004-11-23 | 2026-04-16 |
| CVE-2004-0081 | OpenSSL 0.9.6 before 0.9.6d does not properly handle unknown message types, which allows remote attackers to cause a denial of service (infinite loop), as demonstrated using the Codenomicon TLS Test Tool. | [email protected] | 5.0 | 2.39% | 2004-11-23 | 2026-04-16 |
| CVE-2004-0079 | The do_change_cipher_spec function in OpenSSL 0.9.6c to 0.9.6k, and 0.9.7a to 0.9.7c, allows remote attackers to cause a denial of service (crash) via a crafted SSL/TLS handshake that triggers a null dereference. | [email protected] | 7.5 | 2.28% | 2004-11-23 | 2026-04-16 |
| CVE-2003-1004 | Cisco PIX firewall 6.2.x through 6.2.3, when configured as a VPN Client, allows remote attackers to cause a denial of service (dropped IPSec tunnel connection) via an IKE Phase I negotiation request to the outside interface of the firewall. | [email protected] | 5.0 | 0.66% | 2004-01-05 | 2026-04-16 |
| CVE-2003-1003 | Cisco PIX firewall 5.x.x, and 6.3.1 and earlier, allows remote attackers to cause a denial of service (crash and reload) via an SNMPv3 message when snmp-server is set. | [email protected] | 7.8 | 0.59% | 2004-01-05 | 2026-04-16 |
| CVE-2003-0851 | OpenSSL 0.9.6k allows remote attackers to cause a denial of service (crash via large recursion) via malformed ASN.1 sequences. | [email protected] | 5.0 | 4.24% | 2003-12-01 | 2026-04-16 |
| CVE-2002-0954 | The encryption algorithms for enable and passwd commands on Cisco PIX Firewall can be executed quickly due to a limited number of rounds, which make it easier for an attacker to decrypt the passwords using brute force techniques. | [email protected] | 7.5 | 0.26% | 2002-10-04 | 2026-04-16 |
| CVE-2000-0613 | Cisco Secure PIX Firewall does not properly identify forged TCP Reset (RST) packets, which allows remote attackers to force the firewall to close legitimate connections. | [email protected] | 5.0 | 17.86% | 2000-03-20 | 2026-04-16 |
| CVE-1999-1582 | By design, the "established" command on the Cisco PIX firewall allows connections from one host to arbitrary ports of a target host if an alternative conduit has already been allowed, which can cause administrators to configure less restrictive access controls than intended if they do not understand this functionality. | [email protected] | 7.5 | 2.33% | 1998-07-15 | 2026-04-16 |
