TITLE

Cisco VPN 3000 Concentrator LAN-to-LAN IPSEC capability Denial of service vulnerability

Trust: 0.6

sources: CNNVD: CNNVD-200210-066

DESCRIPTION

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. Cisco has reported a security vulnerability in VPN 3000 series concentrator devices. The vulnerability is related to handling of incoming LAN-to-LAN IPSEC tunnel connections. According to Cisco, this behaviour may be exploitable as a denial of service attack. Furthermore, affected devices do not ensure that the data transmitted across a LAN-to-LAN IPSEC tunnel is sourced from the appropriate network. The implications of this potentially separate issue are not yet known. There are loopholes in the LAN-to-LAN IPSEC capability of Cisco VPN 3000 Concentrator 2.2.x and versions 3.x before 3.5.4
