Vulnerability from variot

Cisco IOS 12.0 through 12.4 on Gigabit Switch Router (GSR) devices (aka 12000 Series routers) allows remote attackers to cause a denial of service (device crash) via a malformed Protocol Independent Multicast (PIM) packet. Cisco IOS is prone to multiple remote denial-of-service vulnerabilities because the software fails to properly handle malformed network datagrams. Successfully exploiting these issues allows remote attackers to cause targeted devices to reload. Multiple exploits can lead to a sustained denial-of-service. These issues are tracked by Cisco Bug IDs CSCsd95616 and CSCsl34355. Cisco IOS is the Internet operating system used on Cisco networking equipment. Cisco has released free software updates that address these vulnerabilities. Workarounds that mitigate these vulnerabilities are available.

Affected Products

Vulnerable Products +------------------

Devices that are running Cisco IOS Software and configured for PIM have a vulnerability related to a specially crafted PIM packet. In addition, Cisco 12000 Series (GSR) routers running Cisco IOS Software have a second vulnerability related to a crafted PIM packet.

The show running-config | include ip pim command can be issued to verify that a Cisco IOS device is configured for PIM. In the following example, the Cisco IOS router is configured for PIM sparse-dense mode. 

Router#show running-config | include ip pim
 ip pim sparse-dense-mode

Note that available PIM modes on a Cisco IOS device are dense mode, sparse mode, or sparse-dense mode. A device that is configured for any of these modes is affected by these vulnerabilities. The mode determines how the device populates its multicast routing table and how multicast packets are forwarded. PIM must be enabled in one of these modes for an interface to perform IP multicast routing. More information on the configuration of each mode is in the "Details" section.

Additionally, To display information about interfaces configured for Protocol Independent Multicast (PIM), use the show ip pim interface command in user EXEC or privileged EXEC mode, as shown in the following example:

Router# show ip pim interface

Address          Interface                Ver/   Nbr    Query  DR     DR
                                          Mode   Count  Intvl  Prior

10.1.0.1         GigabitEthernet0/0       v2/SD  0      30     1      10.1.0.1
10.6.0.1         GigabitEthernet0/1       v2/SD  1      30     1      10.6.0.2

In order to determine the software that runs on a Cisco IOS product, log in to the device and issue the show version command to display the system banner. Cisco IOS software identifies itself as "Internetwork Operating System Software" or simply "IOS." On the next line of output, the image name displays between parentheses, followed by "Version" and the Cisco IOS release name. Other Cisco devices do not have the show version command or give different output.

The following example shows output from a device that runs an IOS image:

router>show version
Cisco IOS Software, 7200 Software (C7200-ADVSECURITYK9-M), Version 12.4(6)T2, RELEASE SOFTWARE (fc1)

Products Confirmed Not Vulnerable +--------------------------------

Cisco IOS devices that are not configured for PIM are not vulnerable. Cisco IOS XR Software is not affected by this vulnerability. No other Cisco products are currently known to be affected by this vulnerability. Devices that run Cisco IOS Software and are configured for PIM are affected by the first vulnerability. Only Cisco 12000 Series (GSR) routers that are configured for PIM are affected by the second vulnerability.

Available PIM modes on a Cisco IOS device are dense mode, sparse mode, or sparse-dense mode. The mode determines how the device populates its multicast routing table and how multicast packets are forwarded. PIM must be enabled in one of these modes for an interface to perform IP multicast routing.

Note: There is no default mode setting. By default, multicast routing is disabled on an interface.

To configure PIM on an interface to be in dense mode, use the following command in interface configuration mode:

Router(config-if)# ip pim dense-mode

To configure PIM on an interface to be in sparse mode, use the following command in interface configuration mode:

Router(config-if)# ip pim sparse-mode

To configure PIM on an interface to be in sparse-dense mode, use the following command in interface configuration mode:

Router(config-if)# ip pim sparse-dense-mode

These vulnerabilities are documented in the following Cisco Bug IDs:

  • CSCsd95616 - Crafted PIM packets may cause an IOS device to reload
  • CSCsl34355 - GSR may crash with malformed PIM packets

These vulnerabilities have been assigned the Common Vulnerabilities and Exposures (CVE) identifiers CVE-2008-3808 and CVE-2008-3809.

Software Versions and Fixes

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 Cisco IOS software table (below) names a Cisco IOS release train. If a given release train is vulnerable, then the earliest possible releases that contain the fix (along with the anticipated date of availability for each, if applicable) are listed in the "First Fixed Release" column of the table. The "Recommended Release" column indicates the releases which have fixes for all the published vulnerabilities at the time of this Advisory. A device running a release in the given train that is earlier than the release in a specific column (less than the First Fixed Release) is known to be vulnerable. Cisco recommends upgrading to a release equal to or later than the release in the "Recommended Releases" column of the table.

Workarounds

Specifying trusted PIM neighbors is a workaround for both vulnerabilities. A PIM router must receive PIM Hellos to establish PIM neighborship. PIM neighborship is also the basis for designated router (DR) election, DR failover, and accepting/sending PIM Join/ Prune/Assert messages. To specify trusted PIM neighbors, use the ip pim neighbor-filter command, as shown in the following example:

Router(config)#access-list 1 permit host 10.10.10.123

!-- An access control list is created to allow a trusted PIM neighbor
!-- in this example the neighbor is 10.10.10.123
!

Router(config)#interface fastEthernet 0/0
Router(config-if)#ip pim neighbor-filter 1

!-- The PIM neighbor filter is then applied to the respective interface(s)

The ip pim neighbor-filter command filters PIM packets from untrusted devices including Hellos, Join/Prune, and BSR packets.

Note: The vulnerabilities described in this document can be exploited by spoofed IP packets if the attacker knows the IP address of the trusted PIM neighbors listed in the ip pim neighbor-filter implementation.

To protect infrastructure devices and minimize the risk, impact, and effectiveness of direct infrastructure attacks, administrators are advised to deploy ACLs to perform policy enforcement of traffic sent to core infrastructure equipment. PIM is IP protocol 103. As an additional workaround, administrators can explicitly permit only authorized PIM (IP protocol 103) traffic sent to infrastructure devices in accordance with existing security policies and configurations. An ACL can be deployed as shown in the following example:

ip access-list extended Infrastructure-ACL-Policy

 !
 !-- When applicable, include explicit permit statements for trusted
 !-- sources that require access on the vulnerable protocol
 !-- PIM routers need to communicate with the rendezvous point (RP). 
 !-- In this example, 192.168.100.1 is the IP address of the 
 !-- rendezvous point, which is a trusted host that requires access 
 !-- to and from the affected PIM devices. 
 !

 permit pim host 192.168.100.1 192.168.60.0 0.0.0.255
 permit pim 192.168.60.0 0.0.0.255 host 192.168.100.1

 !
 !-- Permit PIM segment traffic, packets have destination of:
 !-- 224.0.0.13 (PIMv2)
 !-- 224.0.0.2  (Required only by legacy PIMv1)
 !

 permit pim 192.168.60.0 0.0.0.255 host 224.0.0.13
 permit pim 192.168.60.0 0.0.0.255 host 224.0.0.2

 !
 !-- The following vulnerability-specific access control entries
 !-- (ACEs) can aid in identification of attacks
 !

 deny pim any 192.168.60.0 0.0.0.255

 !
 !-- Explicit deny ACE for traffic sent to addresses configured within
 !-- the infrastructure address space
 !

 deny ip any 192.168.60.0 0.0.0.255

 !
 !-- Permit/deny all other Layer 3 and Layer 4 traffic in accordance
 !-- with existing security policies and configurations
 !
 !-- Apply iACL to interfaces in the ingress direction
 !

All Cisco security advisories are available at http://www.cisco.com/go/psirt -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.8 (Darwin)

iEYEARECAAYFAkjaLdEACgkQ86n/Gc8U/uBLYQCfbFNaZROaq5OZX5KzZAVwv0gr oBwAoJeb3PdxAWcVg3sBKladJgqbb1oy =f4p/ -----END PGP SIGNATURE----- .

1) An unspecified error exists in the processing of SSL packets during the termination of an SSL session, which can potentially be exploited to crash an affected system.

3) Unspecified errors within the processing of segmented Skinny Call Control Protocol (SCCP) messages can be exploited to cause a Cisco IOS device to reload.

Successful exploitation requires that the device is configured with Network Address Translation (NAT) SCCP Fragmentation Support.

4) A memory leak in the processing of Session Initiation Protocol (SIP) messages can be exploited to cause a DoS for all voice services.

5) Multiple unspecified errors exist in the processing of SIP messages, which can be exploited to cause a reload of an affected device.

6) An unspecified error in the IOS Intrusion Prevention System (IPS) feature when processing certain IPS signatures that use the SERVICE.DNS engine can be exploited to cause a DoS via specially crafted network traffic.

7) A security issue exists in the processing of extended communities with Multi Protocol Label Switching (MPLS) Virtual Private Networks (VPN), which can lead to traffic leaking from one MPLS VPN to another.

NOTE: This security issue was introduced with CSCee83237.

8) An unspecified error within the Multi Protocol Label Switching (MPLS) Forwarding Infrastructure (MFI) can be exploited to cause a DoS via specially crafted network packets.

Successful exploitation requires access to the MPLS network.

9) An unspecified error within the Application Inspection Control (AIC) can be exploited to cause a reload of an affected device via specially crafted HTTP packets.

10) An unspecified error in the processing of Layer 2 Tunneling Protocol (L2TP) packets can be exploited to cause an affected device to reload via a specially crafted L2TP packets.

Successful exploitation requires that the L2TP mgmt daemon process is running. This process may be enabled e.g. via Layer 2 virtual private networks (L2VPN), Layer 2 Tunnel Protocol Version 3 (L2TPv3), Stack Group Bidding Protocol (SGBP), or Cisco Virtual Private Dial-Up Networks (VPDN).

11) An unspecified error exists in the processing of IPC messages. This can be exploited to reload an affected device via a specially crafted UDP packet sent to port 1975.

12) A security issue is caused due to the device automatically enabling SNMP with a default community string, which can be exploited to gain control an affected system.

SOLUTION: Update to the fixed version (please see the vendor's advisories for details).

PROVIDED AND/OR DISCOVERED BY: Reported by the vendor.

    "data": "Cisco IOS 12.0 through 12.4 on Gigabit Switch Router (GSR) devices (aka 12000 Series routers) allows remote attackers to cause a denial of service (device crash) via a malformed Protocol Independent Multicast (PIM) packet. Cisco IOS is prone to multiple remote denial-of-service vulnerabilities because the software fails to properly handle malformed network datagrams. \nSuccessfully exploiting these issues allows remote attackers to cause targeted devices to reload.  Multiple exploits can lead to a sustained denial-of-service. \nThese issues are tracked by Cisco Bug IDs CSCsd95616 and CSCsl34355. Cisco IOS is the Internet operating system used on Cisco networking equipment. Cisco has released free software updates\nthat address these vulnerabilities. Workarounds that mitigate these\nvulnerabilities are available. \n\nThis advisory is posted at \nhttp://www.cisco.com/warp/public/707/cisco-sa-20080924-multicast.shtml\n\nNote: The September 24, 2008 IOS Advisory bundled publication\nincludes twelve Security Advisories. Eleven of the advisories address\nvulnerabilities in Cisco\u0027s IOS software, and one advisory addresses\nvulnerabilities in Cisco Unified Communications Manager. Each\nAdvisory lists the releases that correct the vulnerability described\nin the Advisory. Please reference the following software table to\nfind a release that fixes all published IOS software Advisories as of\nSeptember 24th, 2008:\n\nhttp://www.cisco.com/warp/public/707/cisco-sa-20080924-bundle.shtml\n\nIndividual publication links are listed below:\n\n  * http://www.cisco.com/warp/public/707/cisco-sa-20080924-iosips.shtml\n  * http://www.cisco.com/warp/public/707/cisco-sa-20080924-ssl.shtml\n  * http://www.cisco.com/warp/public/707/cisco-sa-20080924-sip.shtml\n  * http://www.cisco.com/warp/public/707/cisco-sa-20080924-cucm.shtml\n  * http://www.cisco.com/warp/public/707/cisco-sa-20080924-vpn.shtml\n  * http://www.cisco.com/warp/public/707/cisco-sa-20080924-mfi.shtml\n  * http://www.cisco.com/warp/public/707/cisco-sa-20080924-ipc.shtml\n  * http://www.cisco.com/warp/public/707/cisco-sa-20080924-ubr.shtml\n  * http://www.cisco.com/warp/public/707/cisco-sa-20080924-sccp.shtml\n  * http://www.cisco.com/warp/public/707/cisco-sa-20080924-iosfw.shtml\n  * http://www.cisco.com/warp/public/707/cisco-sa-20080924-l2tp.shtml\n\nAffected Products\n=================\n\nVulnerable Products\n+------------------\n\nDevices that are running Cisco IOS Software and configured for PIM\nhave a vulnerability related to a specially crafted PIM packet. In\naddition, Cisco 12000 Series (GSR) routers running Cisco IOS Software\nhave a second vulnerability related to a crafted PIM packet. \n\nThe show running-config | include ip pim command can be issued to\nverify that a Cisco IOS device is configured for PIM. In the\nfollowing example, the Cisco IOS router is configured for PIM\nsparse-dense mode. \n\n    Router#show running-config | include ip pim\n     ip pim sparse-dense-mode\n\nNote that available PIM modes on a Cisco IOS device are dense mode,\nsparse mode, or sparse-dense mode. A device that is configured for\nany of these modes is affected by these vulnerabilities. The mode\ndetermines how the device populates its multicast routing table and\nhow multicast packets are forwarded. PIM must be enabled in one of\nthese modes for an interface to perform IP multicast routing. More\ninformation on the configuration of each mode is in the \"Details\"\nsection. \n\nAdditionally, To display information about interfaces configured for\nProtocol Independent Multicast (PIM), use the show ip pim interface\ncommand in user EXEC or privileged EXEC mode, as shown in the\nfollowing example:\n\n    Router# show ip pim interface\n\n    Address          Interface                Ver/   Nbr    Query  DR     DR\n                                              Mode   Count  Intvl  Prior\n\n    10.1.0.1         GigabitEthernet0/0       v2/SD  0      30     1      10.1.0.1\n    10.6.0.1         GigabitEthernet0/1       v2/SD  1      30     1      10.6.0.2\n\nIn order to determine the software that runs on a Cisco IOS product,\nlog in to the device and issue the show version command to display\nthe system banner. Cisco IOS software identifies itself as\n\"Internetwork Operating System Software\" or simply \"IOS.\" On the next\nline of output, the image name displays between parentheses, followed\nby \"Version\" and the Cisco IOS release name. Other Cisco devices do\nnot have the show version command or give different output. \n\nThe following example shows output from a device that runs an IOS\nimage:\n\n    router\u003eshow version\n    Cisco IOS Software, 7200 Software (C7200-ADVSECURITYK9-M), Version 12.4(6)T2, RELEASE SOFTWARE (fc1)\n    Technical Support: http://www.cisco.com/techsupport\n    Copyright (c) 1986-2006 by Cisco Systems, Inc. \n    Compiled Tue 16-May-06 16:09 by kellythw\n    \u003cmore output removed for brevity\u003e\n\nProducts Confirmed Not Vulnerable\n+--------------------------------\n\nCisco IOS devices that are not configured for PIM are not vulnerable. \nCisco IOS XR Software is not affected by this vulnerability. No other\nCisco products are currently known to be affected by this\nvulnerability. Devices that run Cisco IOS Software and\nare configured for PIM are affected by the first vulnerability. Only\nCisco 12000 Series (GSR) routers that are configured for PIM are\naffected by the second vulnerability. \n\nAvailable PIM modes on a Cisco IOS device are dense mode, sparse\nmode, or sparse-dense mode. The mode determines how the device\npopulates its multicast routing table and how multicast packets are\nforwarded. PIM must be enabled in one of these modes for an interface\nto perform IP multicast routing. \n\nNote: There is no default mode setting. By default, multicast routing\nis disabled on an interface. \n\nTo configure PIM on an interface to be in dense mode, use the\nfollowing command in interface configuration mode:\n\n    Router(config-if)# ip pim dense-mode\n\nTo configure PIM on an interface to be in sparse mode, use the\nfollowing command in interface configuration mode:\n\n    Router(config-if)# ip pim sparse-mode\n\nTo configure PIM on an interface to be in sparse-dense mode, use the\nfollowing command in interface configuration mode:\n\n    Router(config-if)# ip pim sparse-dense-mode\n\nThese vulnerabilities are documented in the following Cisco Bug IDs:\n\n  * CSCsd95616 - Crafted PIM packets may cause an IOS device to\n    reload\n  * CSCsl34355 - GSR may crash with malformed PIM packets\n\nThese vulnerabilities have been assigned the Common Vulnerabilities\nand Exposures (CVE) identifiers CVE-2008-3808 and CVE-2008-3809. \n\nVulnerability Scoring Details\n=============================\n\nCisco has provided scores for the vulnerabilities in this advisory\nbased on the Common Vulnerability Scoring System (CVSS). The CVSS\nscoring in this Security Advisory is done in accordance with CVSS\nversion 2.0. \n\nCVSS is a standards-based scoring method that conveys vulnerability\nseverity and helps determine urgency and priority of response. \n\nCisco has provided a base and temporal score. Customers can then\ncompute environmental scores to assist in determining the impact of\nthe vulnerability in individual networks. \n\nCisco has provided an FAQ to answer additional questions regarding\nCVSS at\n\nhttp://www.cisco.com/web/about/security/intelligence/cvss-qandas.html\n\nCisco has also provided a CVSS calculator to help compute the\nenvironmental impact for individual networks at\n\nhttp://intellishield.cisco.com/security/alertmanager/cvss\n\n\nCSCsd95616 - Crafted PIM packets may cause an IOS device to reload\n\nCVSS Base Score - 7.8\n\n        Access Vector          - Network\n        Access Complexity      - Low\n        Authentication         - None\n        Confidentiality Impact - None\n        Integrity Impact       - None\n        Availability Impact    - Complete\n\nCVSS Temporal Score - 6.4\n\n        Exploitability          - Functional\n        Remediation Level       - Official-Fix\n        Report Confidence       - Confirmed\n\n\nCSCsl34355 - GSR may crash with malformed PIM packets\n\nCVSS Base Score - 7.8\n\n        Access Vector          - Network\n        Access Complexity      - Low\n        Authentication         - None\n        Confidentiality Impact - None\n        Integrity Impact       - None\n        Availability Impact    - Complete\n\nCVSS Temporal Score - 6.4\n\n        Exploitability          - Functional\n        Remediation Level       - Official-Fix\n        Report Confidence       - Confirmed\n\n\nImpact\n======\n\nSuccessful exploitation may cause a reload of the affected device. \nRepeated exploitation could result in a sustained denial of service\n(DoS) condition. \n\nSoftware Versions and Fixes\n===========================\n\nWhen considering software upgrades, also consult \nhttp://www.cisco.com/go/psirt and any subsequent advisories to \ndetermine exposure and a complete upgrade solution. \n\nIn all cases, customers should exercise caution to be certain the\ndevices to be upgraded contain sufficient memory and that current\nhardware and software configurations will continue to be supported\nproperly by the new release. If the information is not clear, contact\nthe Cisco Technical Assistance Center (TAC) or your contracted\nmaintenance provider for assistance. \n\nEach row of the Cisco IOS software table (below) names a Cisco IOS\nrelease train. If a given release train is vulnerable, then the\nearliest possible releases that contain the fix (along with the\nanticipated date of availability for each, if applicable) are listed\nin the \"First Fixed Release\" column of the table. The \"Recommended\nRelease\" column indicates the releases which have fixes for all the\npublished vulnerabilities at the time of this Advisory. A device\nrunning a release in the given train that is earlier than the release\nin a specific column (less than the First Fixed Release) is known to\nbe vulnerable. Cisco recommends upgrading to a release equal to or\nlater than the release in the \"Recommended Releases\" column of the\ntable. \n\n+-------------------------------------------------------------------+\n|   Major    |             Availability of Repaired Releases        |\n|  Release   |                                                      |\n|------------+------------------------------------------------------|\n|  Affected  |                                       | Recommended  |\n| 12.0-Based |          First Fixed Release          |   Release    |\n|  Releases  |                                       |              |\n|------------+---------------------------------------+--------------|\n|            |                                       | 12.4(15)T7   |\n| 12.0       | Vulnerable;

A PIM router must receive PIM Hellos to establish\nPIM neighborship. PIM neighborship is also the basis for designated\nrouter (DR) election, DR failover, and accepting/sending PIM Join/\nPrune/Assert messages. To specify trusted PIM neighbors, use the ip\npim neighbor-filter command, as shown in the following example:\n\n    Router(config)#access-list 1 permit host 10.10.10.123\n\n    !-- An access control list is created to allow a trusted PIM neighbor\n    !-- in this example the neighbor is 10.10.10.123\n    !\n\n    Router(config)#interface fastEthernet 0/0\n    Router(config-if)#ip pim neighbor-filter 1\n\n    !-- The PIM neighbor filter is then applied to the respective interface(s)\n\n\nThe ip pim neighbor-filter command filters PIM packets from untrusted\ndevices including Hellos, Join/Prune, and BSR packets. \n\nNote: The vulnerabilities described in this document can be exploited\nby spoofed IP packets if the attacker knows the IP address of the\ntrusted PIM neighbors listed in the ip pim neighbor-filter\nimplementation. \n\nTo protect infrastructure devices and minimize the risk, impact, and\neffectiveness of direct infrastructure attacks, administrators are\nadvised to deploy ACLs to perform policy enforcement of traffic sent\nto core infrastructure equipment. PIM is IP protocol 103. As an\nadditional workaround, administrators can explicitly permit only\nauthorized PIM (IP protocol 103) traffic sent to infrastructure\ndevices in accordance with existing security policies and\nconfigurations. An ACL can be deployed as shown in the following\nexample:\n\n    ip access-list extended Infrastructure-ACL-Policy\n\n     !\n     !-- When applicable, include explicit permit statements for trusted\n     !-- sources that require access on the vulnerable protocol\n     !-- PIM routers need to communicate with the rendezvous point (RP). \n     !-- In this example, 192.168.100.1 is the IP address of the \n     !-- rendezvous point, which is a trusted host that requires access \n     !-- to and from the affected PIM devices. \n     !\n\n     permit pim host 192.168.100.1 192.168.60.0 0.0.0.255\n     permit pim 192.168.60.0 0.0.0.255 host 192.168.100.1\n\n     !\n     !-- Permit PIM segment traffic, packets have destination of:\n     !-- 224.0.0.13 (PIMv2)\n     !-- 224.0.0.2  (Required only by legacy PIMv1)\n     !\n\n     permit pim 192.168.60.0 0.0.0.255 host 224.0.0.13\n     permit pim 192.168.60.0 0.0.0.255 host 224.0.0.2\n\n     !\n     !-- The following vulnerability-specific access control entries\n     !-- (ACEs) can aid in identification of attacks\n     !\n\n     deny pim any 192.168.60.0 0.0.0.255\n\n     !\n     !-- Explicit deny ACE for traffic sent to addresses configured within\n     !-- the infrastructure address space\n     !\n\n     deny ip any 192.168.60.0 0.0.0.255\n\n     !\n     !-- Permit/deny all other Layer 3 and Layer 4 traffic in accordance\n     !-- with existing security policies and configurations\n     !\n     !-- Apply iACL to interfaces in the ingress direction\n     !\n\n    interface GigabitEthernet0/0\n     ip access-group Infrastructure-ACL-Policy in\n\nObtaining Fixed Software\n========================\n\nCisco has released free software updates that address these\nvulnerabilities.
