The Neighbor Discovery (ND) protocol implementation in the IPv6 stack on Cisco Adaptive Security Appliances (ASA) 5500 series devices with software 8.2(3) and earlier, and Cisco PIX Security Appliances devices, allows remote attackers to cause a denial of service (CPU consumption and device hang) by sending many Router Advertisement (RA) messages with different source addresses, as demonstrated by the flood_router6 program in the thc-ipv6 package, aka Bug ID CSCti24526. The problem is Bug ID CSCti24526 It is a problem.A large amount of different source addresses by a third party RA Interfering with service operation by sending a message (CPU Resource consumption and device hangs ) There is a possibility of being put into a state. The Cisco Adaptive Security Appliance is an adaptive security appliance that provides modules for security and VPN services. Multiple vendors' products are prone to an IPv6-related denial-of-service vulnerability. A remote attacker can exploit this issue to make affected computers and devices unresponsive, denying service to legitimate users. This security advisory is released because Microsoft doesnt want to fix the issue. Cisco did for its IOS and ASA within 3 months. ________________________________________________________________________ Title: ICMPv6 Router Announcement flooding denial of service affecting multiple systems Date: 05 April 2011 URL: http://www.mh-sec.de/downloads/mh-RA_flooding_CVE-2010-multiple.txt ________________________________________________________________________ Vendors: Cisco, Juniper, Microsoft, FreeBSD Affected Products: All Cisco IOS ASA with firmware < November 2010 All Netscreen versions All Windows versions All FreeBSD version Vulnerability: ICMPv6 Router Announcement flooding denial of service Severity: 7.8 (CVE CVSS Score), local network CVEs: CVE-2010-4670, CVE-2010-4671, CVE-2010-4669 ________________________________________________________________________ Update Section: 05 April 2011 Initial release ________________________________________________________________________ Overview: When flooding the local network with random router advertisements, hosts and routers update the network information, consuming all available CPU resources, making the systems unusable and unresponsive. As IPv6 and autoconfiguration are enabled by default, all are affected in their default configuration. For Windows, a personal firewall or similar security product does not protect against this attack. Note: Microsoft does not want to fix this security issue for their products. Impact: Updating the routing tables and configuring IPv6 addresses take up all available CPU resources. Routers and firewalls do not forward traffic. The denial of service is in affect until the flooding is terminated. The exact impact differs from the affected system type: Cisco: 100% traffic loss with autconfiguration active, 80% without. Netscreen: Only affected when the interface is configured as host, traffic is forwarded until the neighbor information times out, then the traffic is lost Windows: 100% CPU, 100% RAM FreeBSD: 100% CPU, additionally IPv6 support can be lost until reboot occasionally. Old Linux kernels are also affected, detailed version information unknown. Description: On IPv6 networks, hosts automatically find out about available routers via ICMPv6 router announcements which are sent by the routers. Additionally, router announcemens are used to replace DHCP by the so called autoconfiguration feature. Windows and FreeBSD - like all modern operating systems - enable IPv6 and autoconfiguration by default and are thereby vulnerable. A personal firewall will not protect against this attack. If a system receives a router announcement of a new router, it updates its routing table with the new router, and if the autoconfiguration flag is set on the announcement (and the host is configured to configure its IPv6 address by this mechanism), the host chooses an IPv6 address from the announced network space. If a network is flooded with random router announcements, systems scramble to update their routing tables and configure IPv6 addresses. Exploit: Flood the network with router advertisements coming from different routers and announcing different network prefixes. A tool to test for this vulnerability is included in the thc-ipv6 package, called flood_router6. Solution: Cisco: IOS fix CSCti24526 , ASA fix CSCti33534 Linux: fixed prior 2010 Netscreen: Juniper waiting for IETF results for how to fix the issue FreeBSD: unknown Windows: Microsoft made clear that they do not plan to issue a fix for this security issue. Workaround: The procession of router announcements must be disabled. Please consult your system manual on how to this for your affected platform. Alternatively, disable IPv6. ________________________________________________________________________ Vendor communication: 10 July 2010 Microsoft informed 10 July 2010 Cisco informed 01 August 2010 Cisco confirms problem, announces fix for October 12 August 2010 Microsoft confirms vulnerability, states no fix will be supplied. 22 November 2010 Cisco confirms fixes are available and started to be deployed in current firmwares 28 December 2010 vendor-sec informed (among other issues) 05 February 2011 FreeBSD informed (made aware via vendor-sec 5 weeks before) 20 February 2011 Juniper informed 09 March 2011 Juniper confirms problem 01 April 2011 Juniper informs that they work with the IETF to develop a standard method to cope with this and similar attacks. ________________________________________________________________________ Contact: Marc Heuse mh@mh-sec.de http://www.mh-sec.de ________________________________________________________________________ The information provided is released "as is" without warranty of any kind.

Successful exploitation of this vulnerability requires valid credentials. 3) An error when handling unspecified IPSEC traffic can be exploited to cause a device to crash via a high volume of traffic. 4) An error in emWEB when handling filename requests can be exploited to crash the daemon by requesting a filename containing white space characters. 5) An error when handling packets during device startup can be exploited to bypass configured access restrictions. 6) An error when handling Online Certificate Status Protocol (OCSP) connection failures can be exploited by OCSP responders to exhaust TCP sockets by rejecting connection attempts. 7) An error in the WebVPN implementation when handling CIFS connections can be exploited to access a share via certain CIFS requests. Successful exploitation of this vulnerability requires valid credentials and CIFS file browsing to be disabled. 8) An error within SMTP inspection can be exploited to bypass the inspection via prepended space characters. 9) An error when handling LDAP connections can be exploited to exhaust memory resources via invalid authentication attempts. 10) An error within SIP inspection can be exploited to crash a device via a high volume of calls (greater than 600). 11) An error in the Mobile User Security (MUS) service when handling HTTP requests from a Web Security Appliance (WSA) can be exploited to bypass authentication via a HEAD request. 12) An error when handling unspecified multicast traffic can be exploited to crash a device. 13) An error when handling LAN-to-LAN (L2L) IPSEC sessions can be exploited to crash a device via a high volume of sessions (greater than 10000).
