A vulnerability in the Internet Group Management Protocol (IGMP) version 3 implementation of Cisco IOS® Software and Cisco IOS XE Software allows a remote unauthenticated attacker to cause a reload of an affected device. Repeated attempts to exploit this vulnerability could result in a sustained denial of service (DoS) condition. Cisco has released free software updates that address this vulnerability. This advisory is posted at http://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20100922-igmp. Note: The September 22, 2010, Cisco IOS Software Security Advisory bundled publication includes six Cisco Security Advisories. Five of the advisories address vulnerabilities in Cisco IOS Software, and one advisory addresses vulnerabilities in Cisco Unified Communications Manager. Each advisory lists the releases that correct the vulnerability or vulnerabilities detailed in the advisory. The table at the following URL lists releases that correct all Cisco IOS Software vulnerabilities that have been published on September 22, 2010, or earlier: http://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20100922-bundle Individual publication links are in "Cisco Event Response: Semiannual Cisco IOS Software Security Advisory Bundled Publication" at the following link: http://www.cisco.com/web/about/security/intelligence/Cisco_ERP_sep10.html

Additional information about Cisco IOS Software release naming conventions is available in White Paper: Cisco IOS and NX-OS Software Reference Guide.Router#show version Cisco IOS Software, 1841 Software (C1841-ADVENTERPRISEK9-M), Version 12.4(20)T, RELEASE SOFTWARE (fc3) Technical Support: http://www.cisco.com/techsupport Copyright (c) 1986-2008 by Cisco Systems, Inc. Compiled Thu 10-Jul-08 20:25 by prod_rel_team
No other Cisco products are currently known to be affected by this vulnerability. Cisco IOS XR Software is not affected by this vulnerability.
The IGMP version 1, IGMP version 2, and IPv6 Multicast Listener Discovery protocol (MLD) features in Cisco IOS and Cisco IOS XE Software are not affected by this vulnerability.
Internet Group Management Protocol (IGMP) is the protocol used by hosts and adjacent routers to manage membership in IP multicast groups. The IGMP version 3 protocol permits source-specific multicast which allows hosts to specify the IP address of the multicast source.
A malformed IGMP packet can cause a vulnerable device to reload. This vulnerability can only be exploited if the malformed IGMP packet is received on an interface that has been enabled for IGMP version 3 and Protocol Independent Multicast (PIM). The malformed IGMP packet destination address can be unicast, multicast, or broadcast and can be addressed to any IP address in the vulnerable device, including loopback addresses.
To exploit this vulnerability, a malformed packet must be received on a vulnerable interface, but it can be addressed to any IP address on the vulnerable device.
Transit traffic will not trigger this vulnerability.
A vulnerable interface configuration requires the PIM mode of operation (sparse-dense, sparse, or dense) to be configured in addition to the ip igmp version 3 command. The three possible configurations that permit exploitation of this vulnerability are:
!--- Interface configured for PIM sparse and IGMPv3 interface GigabitEthernet0/0 ip address 192.168.0.1 255.255.255.0 ip pim sparse-mode ip igmp version 3 !--- Interface configured for PIM sparse-dense and IGMPv3 interface GigabitEthernet0/1 ip address 192.168.1.1 255.255.255.0 ip pim sparse-dense-mode ip igmp version 3 !--- Interface configured for PIM dense and IGMPv3 interface GigabitEthernet0/2 ip address 192.168.2.1 255.255.255.0 ip pim dense-mode ip igmp version 3
The IGMP version 3 lite feature is unrelated to this vulnerability, in that the presence or absence of the ip igmp v3lite command on an interface does not change the vulnerable condition of that interface.
The IP router alert option may or may not be present in packets attempting to exploit the vulnerability described in this document.
This vulnerability is documented in Cisco bug ID CSCte14603 ( registered customers only) . This vulnerability has been assigned Common Vulnerabilities and Exposures (CVE) ID CVE-2010-2830.
Additional mitigations that can be deployed on Cisco devices within the network are available in the Cisco Applied Mitigation Bulletin companion document for this advisory, which is available at the following link: http://tools.cisco.com/security/center/content/CiscoAppliedMitigationBulletin/cisco-amb-20100922-igmp.
Customers who do not require the Source Specific Multicast (SSM) functionality can use IGMP version 2 as a workaround.
interface GigabitEthernet0/0 ip address 192.168.0.1 255.255.255.0 ip pim sparse-mode ip igmp version 2
A partial mitigation of the vulnerability described in this document is to block IGMP packets with an IP Time to Live (TTL) field value that is not equal to 1. RFC1054 , "Host Extensions for IP Multicasting" RFC2236 , "Internet Group Management Protocol Version 2", and RFC3376 , "Internet Group Management Protocol Version 3", indicate that every IGMP message is sent with an IP TTL of 1.
CoPP may be configured on a device to protect the management and control planes, and minimize the risk and effectiveness of direct infrastructure attacks by explicitly permitting only authorized traffic sent to infrastructure devices in accordance with existing security policies and configurations. The following example can be adapted to your network. Drop of IGMP packets with unicast IP destination addresses can also be implemented with CoPP if the network is using all multicast applications that utilize only multicast group destination addresses for IGMP packets.
! !-- The following access list is used !-- to determine what traffic needs to be dropped by a control plane !-- policy (the CoPP feature.) If the access list matches (permit), !-- then traffic will be dropped. If the access list does not !-- match (deny), then traffic will be processed by the router. !-- all IGMP packets with ttl different from 1 will be selected !-- by this acl and the "drop" action will be applied in the !-- corresponding CoPP polisy ! ip access-list extended IGMP-ACL permit igmp any any ttl neq 1 ! !-- Permit (Police or Drop)/Deny (Allow) all other Layer3 and Layer4 !-- traffic in accordance with existing security policies and !-- configurations for traffic that is authorized to be sent !-- to infrastructure devices. !-- Create a class map for traffic that will be policed by !-- the CoPP feature. ! class-map match-all drop-IGMP-class match access-group name IGMP-ACL ! !-- Create a policy map that will be applied to the !-- Control Plane of the device, and add the "drop-tcp-traffic" !-- class map. ! policy-map CoPP-policy class drop-IGMP-class drop ! !-- Apply the policy map to the control plane of the !-- device. ! control-plane service-policy input CoPP-policy
Additional information on the configuration and use of the CoPP feature is available in the Control Plane Policing Implementation Best Practices.
When considering software upgrades, also consult http://www.cisco.com/go/psirt and any subsequent advisories to determine exposure and a complete upgrade solution.
In all cases, customers should exercise caution to be certain the devices to be upgraded contain sufficient memory and that current hardware and software configurations will continue to be supported properly by the new release. If the information is not clear, contact the Cisco Technical Assistance Center (TAC) or your contracted maintenance provider for assistance.
Each row of the following Cisco IOS Software table corresponds to a Cisco IOS Software train. If a particular train is vulnerable, the earliest releases that contain the fix are listed in the First Fixed Release For This Advisory column. The First Fixed Release for All Advisories in the September 2010 Bundle Publication column lists the earliest possible releases that correct all the published vulnerabilities in the Cisco IOS Software Security Advisory bundled publication. Cisco recommends upgrading to the latest available release, where possible.
