| CVE-2006-3906 | | 0.00 | — | 0.04 | | Jul 27, 2006 | 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. |
| CVE-2005-4499 | | 0.00 | — | 0.02 | | Dec 22, 2005 | 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. |
| CVE-2005-2025 | | 0.00 | — | 0.01 | | Jun 20, 2005 | Cisco VPN 3000 Concentrator before 4.1.7.F allows remote attackers to determine valid groupnames by sending an IKE Aggressive Mode packet with the groupname in the ID field, which generates a response if the groupname is valid, but does not generate a response for an invalid groupname. |
| CVE-2005-0943 | | 0.00 | — | 0.01 | | Mar 30, 2005 | Cisco VPN 3000 series Concentrator running firmware 4.1.7.A and earlier allows remote attackers to cause a denial of service (device reload or drop user connection) via a crafted HTTPS packet. |
| CVE-2003-0258 | | 0.00 | — | 0.02 | | May 27, 2003 | Cisco VPN 3000 series concentrators and Cisco VPN 3002 Hardware Client 3.5.x through 4.0.REL, when enabling IPSec over TCP for a port on the concentrator, allow remote attackers to reach the private network without authentication. |
