Ipsec vulnerabilities

Common IPsec vulnerabilities. There are security flaws with another internet key exchange protocol called the “IKEv2.” Numerous differences exist between IKEv1 and IKEv2. The latter is the more recent of the two. Despite IKEv1 being considered obsolete, it is still popular and even used on newer devices. 1. Man in the middle attack

One example of one minimal configuration is the "manual" IPSec SA configuration: security ipsec security-association manual direction protocol ah. Other configurations apply. Juniper SIRT is not aware of any malicious exploitation of these vulnerabilities. These issues were discovered during an external security research. Over the past several years, multiple vulnerabilities have been released related to IPsec VPNs. Many of these vulnerabilities are only mitigated by routinely applying vendor-provided patches to VPN gateways and clients. Many network equipment vendors allow customers to sign up for notification emails for new security alerts.

Multiple unspecified vulnerabilities in the Internet Key Exchange version 1 (IKEv1) implementation in HP HP-UX B.11.00, B.11.11, and B.11.23 running IPSec, HP Jetdirect 635n IPv6/IPsec Print Server, and HP Tru64 UNIX 5.1B-3 and 5.1B-2/PK4, allow remote attackers to cause a denial of service via certain IKE packets, as demonstrated by the PROTOS This means IPSec wraps the original packet, encrypts it, adds a new IP header and sends it to the other side of the VPN tunnel (IPSec peer). Tunnel mode is most commonly used between gateways (Cisco routers or ASA firewalls), or at an end-station to a gateway, the gateway acting as a proxy for the hosts behind it. Feb 17, 2010 · A crafted IKE message that is sent through an IPsec tunnel that terminates on a Cisco ASA 5500 Series Adaptive Security Appliance could cause all IPsec tunnels that terminate on the same device to be torn down. Versions 7.0.x, 7.1.x, 7.2.x, 8.0.x, 8.1.x, and 8.2.x are affected. IKE is not enabled by default.
