Vpn 3000 Concentrator Series Software

Multiple unspecified vulnerabilities in Cisco VPN 3000 series concentrators before 4.1, 4.1.x up to 4.1(7)L, and 4.7.x up to 4.7(2)F allow attackers to execute the (1) CWD, (2) MKD, (3) CDUP, (4) RNFR, (5) SIZE, and (6) RMD FTP commands to modify files or create and delete directories via unknown vectors.Show less

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.Show less

Multiple cross-site scripting (XSS) vulnerabilities in the WebVPN feature in the Cisco VPN 3000 Series Concentrators and Cisco ASA 5500 Series Adaptive Security Appliances (ASA), when in WebVPN clientless mode, allow remote attackers to inject arbitrary web script or HTML via the domain parameter in (1) dnserror.html and (2) connecterror.html, aka bugid CSCsd81095 (VPN3k) and CSCse48193 (ASA). NOTE: the vendor states that "WebVPN full-network-access mode" is not affected, despite the claims by the original researcher.Show less

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.Show less

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.Show less

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.Show less

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.Show less

The LAN-to-LAN IPSEC capability for Cisco VPN 3000 Concentrator 2.2.x, and 3.x before 3.5.4, allows remote attackers to cause a denial of service via an incoming LAN-to-LAN connection with an existing security association with another device on the remote network, which causes the concentrator to remove the previous connection.Show less

Cisco VPN 3000 Concentrator 2.2.x, and 3.x before 3.5.3, adds an "HTTPS on Public Inbound (XML-Auto)(forward/in)" rule but sets the protocol to "ANY" when the XML filter configuration is enabled, which ultimately allows arbitrary traffic to pass through the concentrator.Show less
