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. Protocolo Internet Key Exchange (IKE) version 1, implementado para Cisco IOS, VPN 3000 Concentrators, y PIX firewalls, permite a atacantes remotos provocar denegación de servicio (agotamiento de recursos) a través de un flood de paquetes IKE Phase-1 que exceden el ratio de expiración de la sesión. NOTA: se ha indicado que esto es debido a un diseño debil del protocolo IKe version 1, en cuyo caso otros vendedores e implementaciones podrían verse afectados. • http://archives.neohapsis.com/archives/bugtraq/2006-07/0531.html http://securityreason.com/securityalert/1293 http://securitytracker.com/id?1016582 http://www.cisco.com/en/US/tech/tk583/tk372/tsd_technology_security_response09186a00806f33d4.html http://www.nta-monitor.com/posts/2006/07/cisco-concentrator-dos.html http://www.osvdb.org/29068 http://www.securityfocus.com/archive/1/441203/100/0/threaded http://www.securityfocus.com/bid/19176 https://exchange.xforce.ibmcloud.com/vulnerabilities& •

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. • http://secunia.com/advisories/18141 http://www.cisco.com/en/US/products/sw/secursw/ps2086/products_field_notice09186a00805bf1c4.shtml http://www.osvdb.org/22193 http://www.securityfocus.com/archive/1/420020/100/0/threaded http://www.securityfocus.com/archive/1/420103/100/0/threaded http://www.securityfocus.com/bid/16025 •

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. • http://www.nta-monitor.com/news/vpn-flaws/cisco/VPN-Concentrator/index.htm http://www.securityfocus.com/bid/13992 http://www.vupen.com/english/advisories/2005/0822 •
