Cisco Security Advisory: Cisco IOS Software Multiprotocol Label Switching Packet Vulnerability

Advisory ID: cisco-sa-20100324-ldp

Revision 1.0

For Public Release 2010 March 24 1600 UTC (GMT)

+---------------------------------------------------------------------

Summary =======

A device running Cisco IOS? Software, Cisco IOS XE Software, or Cisco IOS XR Software is vulnerable to a remote denial of service (DoS) condition if it is configured for Multiprotocol Label Switching (MPLS) and has support for Label Distribution Protocol (LDP).

A crafted LDP UDP packet can cause an affected device running Cisco IOS Software or Cisco IOS XE Software to reload. On devices running affected versions of Cisco IOS XR Software, such packets can cause the device to restart the mpls_ldp process.

A system is vulnerable if configured with either LDP or Tag Distribution Protocol (TDP).

Cisco has released free software updates that address this vulnerability.

Workarounds that mitigate this vulnerability are available.

Affected Products =================

Cisco IOS Software, Cisco IOS XE Software, and Cisco IOS XR Software devices are vulnerable if they are configured to listen for either targeted LDP hello messages or link LDP hello messages.

All versions of Cisco IOS Software and Cisco IOS XE Software that support MPLS are affected. Cisco IOS XR Software is affected in releases prior to 3.5.2.

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

Several features within Cisco IOS Software, Cisco IOS XE Software, and Cisco IOS XR Software require the device to listen for either targeted LDP hello messages or link LDP hello messages. The most reliable way to determine if the device is configured to listen to LDP hello messages, is to log into the device and perform these actions:

1. Confirm whether MPLS forwarding is enabled.

A device that has MPLS forwarding disabled, is not vulnerable.

Cisco IOS Software and Cisco IOS XE Software ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

MPLS forwarding is enabled by default in Cisco IOS Software and Cisco IOS XE Software via the CLI command "mpls ip". A device that has MPLS forwarding disabled, will have the global configuration command "no mpls ip" in the configuration. For Cisco IOS Software, the output of "show mpls interface" will show whether the device has it disabled. This example shows a Cisco IOS Software device that has MPLS forwarding disabled:

Router#show mpls interface IP MPLS forwarding is globally disabled on this router. Individual interface configuration is as follows:

Interface IP Tunnel Operational Router#

For Cisco IOS XE Software, examine the output of show running-config and confirm the existence of the global command "no mpls ip | include mpls", to ensure that the device will not process LDP hello messages. This example shows a Cisco IOS XE Software device that has MPLS forwarding disabled:

Router#show running-config | include mpls no mpls ip Router#

Cisco IOS XR Software ~~~~~~~~~~~~~~~~~~~~~

MPLS forwarding is disabled by default in Cisco IOS XR Software.

A device that has MPLS forwarding enabled, will have the global configuration command "mpls ldp" in the configuration. This example shows a Cisco IOS XR Software device that has MPLS forwarding enabled:

RP/0/0/CPU0:Router-XR#show running-config mpls mpls ldp !

RP/0/0/CPU0:Router-XR#

This example shows a Cisco IOS XR Software device with MPLS forwarding disabled:

RP/0/0/CPU0:Router-XR#show running-config mpls % No such configuration item(s)

RP/0/0/CPU0:Router-XR#

If MPLS is disabled the device is not vulnerable and there is no requirement to perform the next step.

2. Confirm whether the device is listening to LDP hello messages.

If a device is configured to listen to LDP hello messages, it is vulnerable.

Cisco IOS Software and Cisco IOS XE Software ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

To determine if a device is configured to listen for LDP hello messages, log into the device and issue either of the following command line interface (CLI) commands "show ip socket", "show udp" or "show control-plane host open-ports". If the output shows any IP addresses listening on port UDP 646, the device is vulnerable. This is an example of a device that is configured to listen for LDP hello messages (one example is shown from each of the above commands):

Router#show ip socket Proto Remote Port Local Port In Out Stat TTY OutputIF 17 --listen-- 192.168.0.1 67 0 0 1 0 17 --listen-- 192.168.0.1 68 0 0 1 0 17 --listen-- 192.168.0.1 711 0 0 1 0 17 --listen-- 192.168.0.1 646 0 0 1 0 17 --listen-- 192.168.0.1 3503 0 0 1 0 Router#

Router#show udp Proto Remote Port Local Port In Out Stat TTY OutputIF 17 --listen-- 192.168.0.1 123 0 0 1 0 17 --listen-- 192.168.0.1 711 0 0 1 0 17 --listen-- 192.168.0.1 646 0 0 1 0 17 --listen-- 192.168.0.1 3503 0 0 1 0 Router#

Router#show control-plane host open-ports Active internet connections (servers and established) Prot Local Address Foreign Address Service State tcp *:23 *:0 Telnet LISTEN udp *:123 *:0 NTP LISTEN udp *:646 *:0 LDP Hello LISTEN udp *:711 *:0 TDP Hello LISTEN

Router#

Cisco IOS XR Software ~~~~~~~~~~~~~~~~~~~~~

To determine if a device is configured to listen for LDP hello messages, log in to the device and issue the "show udp brief" CLI command. If the output shows any IP address listening on port UDP 646, the device is vulnerable. This is an example of a device that is configured to listen for LDP hello messages:

RP/0/0/CPU0:Router-XR#show udp brief PCB Recv-Q Send-Q Local Address Foreign Address 0x482609e8 0 0 :::514 :::0 0x482605f0 0 0 0.0.0.0:514 0.0.0.0:0 0x48260720 0 0 0.0.0.0:646 0.0.0.0:0 RP/0/0/CPU0:Router-XR#

If the device is not listening on UDP port 646, it is not vulnerable. Devices that are configured to only use Resource Reservation Protocol (RSVP) or Border Gateway Protocol (BGP) to distribute labels or MPLS Static Labels are not vulnerable.

To determine the Cisco IOS Software release that is running on a Cisco product, administrators can log in to the device and issue the "show version" command to display the system banner. The system banner confirms that the device is running Cisco IOS Software by displaying text similar to "Cisco Internetwork Operating System Software" or "Cisco IOS Software." The image name displays in parentheses, followed by "Version" and the Cisco IOS Software release name. Other Cisco devices do not have the "show version" command or may provide different output.

This example identifies a Cisco product that is running Cisco IOS Software Release 12.3(26) with an installed image name of C2500-IS-L:

Router#show version Cisco Internetwork Operating System Software IOS (tm) 2500 Software (C2500-IS-L), Version 12.3(26), RELEASE SOFTWARE (fc2) Technical Support: http://www.cisco.com/techsupport Copyright ) 1986-2008 by cisco Systems, Inc. Compiled Mon 17-Mar-08 14:39 by dchih

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

* Cisco NX-OS Software is not affected. * Cisco IOS XR Software Releases 3.5.2 and later are not affected.

No other Cisco products are currently known to be affected by this vulnerability.

Details =======

MPLS LDP enables peer label switch routers (LSRs) in an MPLS network to exchange label binding information for supporting hop-by-hop forwarding in an MPLS network.

A vulnerability exists in Cisco IOS Software, Cisco IOS XE Software, and Cisco IOS XR Software when processing a specially crafted LDP packet. For the device to be vulnerable, it has to be configured to process LDP hello messages, as explained within the Affected Products section of this advisory.

The crafted LDP packet, can be received as either a unicast or multicast UDP packet on port UDP 646 on any listening IP address of the device. Transit traffic will not trigger this vulnerability.

Note: Devices configured with TDP will also process the crafted LDP packet and are vulnerable.

For further information regarding MPLS and LDP please consult the "Multiprotocol Label Switching (MPLS) Introduction" home page available at this link:

Workarounds ===========

Users are advised to apply mitigation techniques to help limit exposure to the vulnerability. Mitigation consists of allowing only legitimate devices to connect to the device. To increase effectiveness, the mitigation must be coupled with anti-spoofing measures on the network edge. This action is required because LDP will use UDP as the hello transport protocol.

If LDP is not required on the device, then MPLS forwarding can be disabled with the global configuration command "no mpls ip".

Note: LDP password or MD5 protection, does not protect against this vulnerability.

Transit traffic will not exploit this vulnerability. Only packets destined to the device may be used to exploit this vulnerability.

Additional mitigations that can be deployed on Cisco devices within the network are available in the companion document "Cisco Applied Mitigation Bulletin: Identifying and Mitigating Exploitation of the Cisco IOS Software Multiprotocol Label Switching Packet Vulnerability," which is available at this location:

Infrastructure Access Control Lists +----------------------------------

Warning: Because the feature in this vulnerability utilizes UDP as a transport, it is possible to spoof the sender's IP address, which may defeat access control lists (ACLs) that permit communication to these ports from trusted IP addresses. Unicast Reverse Path Forwarding (Unicast RPF) should also be considered, to offer a comprehensive solution.

Although it is often difficult to block traffic that transits a network, it is possible to identify traffic that should never be allowed to target infrastructure devices and block that traffic at the border of the network. Infrastructure ACLs (iACLs) are a network security best practice and should be considered as a long-term addition to good network security as well as a workaround for this specific vulnerability. The iACL example below should be included as part of the deployed infrastructure access list, which will help protect all devices with IP addresses in the infrastructure IP address range:

!--- !--- Feature: Label Distribution Protocol (LDP) !---

access-list 150 permit udp TRUSTED_SOURCE_ADDRESSES WILDCARD INFRASTRUCTURE_ADDRESSES WILDCARD eq 646

access-list 150 permit udp TRUSTED_SOURCE_ADDRESSES WILDCARD host 224.0.0.2 eq 646

!--- !--- Deny LDP traffic from all other sources destined !--- to infrastructure addresses. !---

access-list 150 deny udp any INFRASTRUCTURE_ADDRESSES WILDCARD eq 646

!--- !--- Permit/deny all other Layer 3 and Layer 4 traffic in !--- accordance with existing security policies and !--- configurations. Permit all other traffic to transit the !--- device. !---

access-list 150 permit ip any any

!--- !--- Apply access-list to all interfaces (only one example !--- shown) !---

interface fastEthernet 2/0 ip access-group 150 in

The white paper entitled "Protecting Your Core: Infrastructure Protection Access Control Lists" presents guidelines and recommended deployment techniques for infrastructure protection access lists and is available at this link:

Control Plane Policing +---------------------

Warning: Because the feature in this vulnerability utilizes UDP as a transport, it is possible to spoof the sender's IP address, which may defeat ACLs that permit communication to these ports from trusted IP addresses. Unicast RPF should also be considered, to offer a comprehensive solution.

Control Plane Policing (CoPP) can be used to block untrusted UDP traffic to the device. Cisco IOS Software Releases 12.0S, 12.2SX, 12.2S, 12.3T, 12.4, and 12.4T support the CoPP feature. CoPP can be configured on a device to help protect the management and control planes and minimize the risk and effectiveness of direct infrastructure attacks by explicitly permitting only authorized traffic that is sent to infrastructure devices in accordance with existing security policies and configurations. The CoPP example below should be included as part of the deployed CoPP policy, which will help protect all devices with IP addresses in the infrastructure IP address range.

!--- !--- Feature: Label Distribution Protocol (LDP) !---

access-list 150 deny udp TRUSTED_SOURCE_ADDRESSES WILDCARD any eq 646

!--- !--- Deny LDP traffic from all other sources destined !--- to the device control plane. !---

access-list 150 permit udp any any eq 646

!--- !--- 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 to be policed by !--- the CoPP feature !---

class-map match-all drop-ldp-class match access-group 150

!--- !--- Create a Policy-Map that will be applied to the !--- Control-Plane of the device. !---

policy-map control-plane-policy class drop-ldp-class drop

!--- !--- Apply the Policy-Map to the !--- Control-Plane of the device !---

control-plane service-policy input control-plane-policy

In the above CoPP example, the access control entries (ACEs) that match the potential exploit packets with the "permit" action result in these packets being discarded by the policy-map "drop" function, while packets that match the "deny" action (not shown) are not affected by the policy-map drop function. Please note that the policy-map syntax is different in the 12.2S and 12.0S Cisco IOS Software trains:

policy-map control-plane-policy class drop-udp-class police 32000 1500 1500 conform-action drop exceed-action drop

Additional information on the configuration and use of the CoPP feature can be found in the documents, "Control Plane Policing Implementation Best Practices" and "Cisco IOS Software Releases 12.2 S - Control Plane Policing" at these links:

Receive ACLs (rACL) +------------------

Warning: Because the feature in this vulnerability utilizes UDP as a transport, it is possible to spoof the sender's IP address, which may defeat ACLs that permit communication to these ports from trusted IP addresses. Unicast RPF should also be considered, to offer a comprehensive solution.

For distributed platforms, Receive ACLs may be an option starting in Cisco IOS Software Versions 12.0(21)S2 for the 12000 (GSR), 12.0(24)S for the 7500, and 12.0(31)S for the 10720. The Receive ACL protects the device from harmful traffic before the traffic can impact the route processor. Receive ACLs are designed to only protect the device on which it is configured. On the 12000, 7500, and 10720, transit traffic is never affected by a receive ACL. Because of this, the destination IP address "any" used in the example ACL entries below only refer to the router's own physical or virtual IP addresses. Receive ACLs are considered a network security best practice, and should be considered as a long-term addition to good network security, as well as a workaround for this specific vulnerability. The white paper entitled "GSR: Receive Access Control Lists" will help you identify and allow legitimate traffic to your device and deny all unwanted packets. This white paper is available at the following link:

http://www.cisco.com/en/US/tech/tk648/tk361/technologies_white_paper09186a00...

The following is the receive path ACL written to permit this type of traffic from trusted hosts:

!--- !--- Feature: Label Distribution Protocol (LDP) !---

!--- !--- Permit LDP traffic from all trusted sources allowed !--- to infrastructure addresses. !---

access-list 150 permit udp TRUSTED_SOURCE_ADDRESSES WILDCARD any eq 646

!--- !--- Deny LDP traffic from all other sources destined !--- to infrastructure addresses. !---

access-list 150 deny udp any any eq 646

!--- !--- Permit all other traffic to the RP. !--- according to security policy and configurations. !---

access-list 150 permit ip any any

!--- !--- Apply this access list to the 'receive' path. !---

ip receive access-list 150
