CVE ID: CVE-2013-1194
Release Date: 2013 April 17 12:00 UTC (GMT)
Last Updated: 2013 April 17 12:00 UTC (GMT)
SummaryA vulnerability in the Internet Security Association and Key Management Protocol (ISAKMP) implementation in Cisco Adaptive Security Appliance (ASA) Software could allow an unauthenticated, remote attacker to enumerate remote access VPN groups configured in a Cisco ASA device.
The vulnerability is due to differences in the way Cisco ASA Software responds to Internet Key Exchange (IKE) aggressive mode messages when valid and invalid VPN groups are provided in the AM1 message. An attacker could exploit this vulnerability by sending crafted IKE messages to a Cisco ASA device that is configured as a VPN headend.
This vulnerability was discovered by Daniel Turner of Trustwave SpiderLabs. Cisco would like to thank Trustwave SpiderLabs for reporting this issue and working with us toward coordinated disclosure of this vulnerability.
