Affected Products
=================
Vulnerable Products
+------------------
Devices that are running affected versions of Cisco IOS Software and
Cisco IOS XE Software are affected if they are running any of the
following features. Details about confirming whether the affected
feature is enabled on a device are in the "Details" section of this
advisory.
* Cisco Unified Communications Manager Express
* SIP Gateway Signaling Support Over Transport Layer Security (TLS)
Transport
* Secure Signaling and Media Encryption
* Blocks Extensible Exchange Protocol (BEEP)
* Network Admission Control HTTP Authentication Proxy
* Per-user URL Redirect for EAPoUDP, Dot1x, and MAC Authentication
Bypass
* Distributed Director with HTTP Redirects
* DNS (TCP mode only)
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.
The following example identifies a Cisco product that is running
Cisco IOS Software Release 12.3(26) with an installed image name of
C2500-IS-L:

For successful exploitation of this vulnerability, the TCP three-way
handshake must be completed to the associated TCP port number(s) for
any of the features described in this section.
Cisco Unified Communications Manager Express
+-------------------------------------------
The following configurations are vulnerable for different Cisco
Unified Communications Manager Express services:
A certificate authority proxy function (CAPF) server has been
configured.
The following example shows a vulnerable CAPF server configuration:
capf-server
auth-mode null-string
cert-enroll-trustpoint root password 1 104D000A061843595F
trustpoint-label cme_cert
source-addr 10.0.0.1
The default TCP port used for CAPF server is 3804.
Further information about CAPF-server is in the Cisco Unified
Communications Manager Express System Administrator Guide at
http://www.cisco.com/en/US/docs/voice_ip_comm/cucme/admin/configuration/guide/cmeauth.html#wp1085744
Telephony-service security parameters have been configured.
If the telephony-service security parameters have been configured
with "device-security-mode", the device is vulnerable. The following
example shows three vulnerable configurations for telephony-service
security parameters:
ephone 1
device-security-mode encrypted
ephone 2
device-security-mode authenticated
ephone 3
device-security-mode none
The TCP port used is defined with the "ip source-address <address>
port <port-number>" telephony-service configuration command.
Further information about Telephony-service security parameters is in
the Cisco Unified Communications Manager Express System Administrator
Guide at
http://www.cisco.com/en/US/docs/voice_ip_comm/cucme/admin/configuration/guide/cmeauth.html#wp1080079
The global telephony-service or call-manager-fallback command has
been configured.
Any Cisco IOS configuration with the global "telephony-service" or
"call-manager-fallback" command is vulnerable if any subcommands are
in the telephony-service or call-manager-fallback configuration mode.
The following examples show vulnerable configurations:
telephony-service
ip source-address 192.168.0.1 port 2011
or
call-manager-fallback
ip source-address 192.168.0.1 port 2011
The TCP port used is defined with the "ip source-address <address>
port <port-number>" configuration command.
Further information about telephony service and call-manager-fallback
is in the Cisco Unified Communications Manager Express System
Administrator Guide at
http://www.cisco.com/en/US/docs/voice_ip_comm/cucme/admin/configuration/guide/cmesystm.html
SIP Gateway Signaling Support over TLS Transport
+----------------------------------------------
Note: For customers with devices enabled with SIP, also consult the
document "Cisco Security Advisory: Cisco IOS Session Initiation
Protocol Denial of Service Vulnerability" at the following link
http://www.cisco.com/warp/public/707/cisco-sa-20090325-sip.html
Devices that are configured for SIP gateway signaling support over
TLS transport are vulnerable. The following examples show vulnerable
configurations:
voice service voip
sip
session transport tcp tls
url sips
- -- or --
dial-peer voice 3456 voip
voice-class sip url sips
session protocol sipv2
session transport tcp tls
For the SIP gateway signaling support over TLS transport to function
correctly, administrators must first configure a trustpoint using the
following configuration:
sip-ua
crypto signaling default trustpoint example_trustpoint_name
The default TCP port used for the SIP gateway signaling support over
TLS transport feature is 5061.
Further information about Cisco IOS SIP gateway signaling support
over TLS transport is in the Cisco IOS Software Release 12.4T feature
guide at
http://www.cisco.com/en/US/docs/ios/12_4t/12_4t11/FeatTLS.html
Secure Signaling and Media Encryption
+------------------------------------
A device is vulnerable if it is configured with the Media and
Signaling Encryption (SRTP/TLS) on DSP Farm Conferencing feature or
with Secure Signaling and Media Encryption for analog phones with
Skinny Call Control Protocol (SCCP).
The following examples show three different vulnerable secure DSP
farm configurations. Several other parts are required for a full
configuration, such as certificates and SCCP configuration, but these
parts have been excluded for brevity.
dspfarm profile 2 transcode security
trustpoint 2851ClientMina

The default TCP port used for Media and Signaling Encryption for
analog phones is 2443.
Further information about Media and Signaling Encryption for analog
phones is in the "Supplementary Services Features for FXS Ports on
Cisco IOS Voice Gateways Configuration Guide, Release 12.4T" at the
following link
http://www.cisco.com/en/US/docs/ios/voice/fxs/configuration/guide/fsxsecur.html
Blocks Extensible Exchange Protocol
+----------------------------------
Any configuration or executable command that leverages Blocks
Extensible Exchange Protocol (BEEP) as a transport protocol is
vulnerable. The following example shows the vulnerable configuration
of the feature NETCONF over BEEP. NETCONF over BEEP using SASL is
also vulnerable.
crypto key generate rsa general-keys
crypto pki trustpoint my_trustpoint
enrollment url http://10.2.3.3:80
subject-name CN=dns_name_of_host.com
revocation-check none
crypto pki authenticate my_trustpoint
crypto pki enroll my_trustpoint
line vty 0 15
netconf lock-time 60
netconf max-sessions 16
netconf beep initiator host1 23 user my_user password
my_password encrypt my_trustpoint
reconnect-time 60
netconf beep listener 23 sasl user1 encrypt my_trustpoint
The TCP port used is defined with the "netconf beep initiator" and
"netconf beep listener" configuration commands.
Further information about NETCONF over BEEP is in the "Cisco IOS
Software Release 12.4T feature guide" at the following link
http://www.cisco.com/en/US/docs/ios/12_4t/12_4t11/htnetbe.html#wp1049404
The BEEP executable commands "bingd" and "bingng" could cause this
vulnerability to be triggered when they are invoked. The following
shows an example of these commands being executed:
bingng device 192.168.0.1 23
bingd device 23
Network Admission Control HTTP Authentication Proxy
+--------------------------------------------------
Devices configured with Network Admission Control HTTP Authentication
Proxy are vulnerable. For the device to be vulnerable the
authentication proxy rule must exist and be applied to an interface.
The following configuration creates an authentication proxy rule.
ip admission name example-ap-rule-name proxy http
The following configuration attaches the authentication proxy rule
(created in the previous example) to an interface.
interface GigabitEthernet 0/0
ip admission example-ap-rule-name
The default TCP port used for Network Admission Control HTTP
Authentication Proxy is 80.
Further information about Network Admission Control HTTP
Authentication Proxy is in the "Cisco IOS Security Configuration
Guide, Release 12.4" at the following link
http://www.cisco.com/en/US/docs/ios/security/configuration/guide/sec_net_admssn_ctrl_ps6350_TSD_Products_Configuration_Guide_Chapter.html#wp1053957
Per-user URL Redirect for EAPoUDP, Dot1x, and MAC Authentication Bypass
+----------------------------------------------------------------------
Devices that have URL redirect feature configured are vulnerable. URL
redirect is supported for EAP over UDP (EAPoUDP), Dot1x and MAC
Authentication Bypass (MAB) authentication mechanisms. The URL
redirect configuration can either be on the server or set up as part
of a locally defined profile or policy. Both configurations are
vulnerable. A device is vulnerable with either of the following
configurations.
URL Redirect Feature Enabled for EAPoUDP
+---------------------------------------
The URL redirect feature is enabled for EAPoUDP with the following
global configuration command:
ip admission name <EAPoUDP-rule-name> eapoudp
The following configuration attaches the EAPoUDP rule (created in the
previous example) to an interface.
ip admission name <EAPoUDP-rule-name>
URL Redirect Feature Enabled for Dot1x and MAB
+---------------------------------------------
The URL redirect feature for both Dot1x and MAB are vulnerable and
will have a URL redirect AV pair on the RADIUS server defined in a
method that is similar to the following:
url-redirect="http://example.com"
url-redirect="urlacl"
For the Dot1x and MAB URL redirect feature to work successfully on
the switch, the minimum following configuration would also be
required. There is no interface-specific configuration for URL
redirect. Basically the interface has to be configured for Dot1x/MAB.
ip http {server | secure-server}
ip device tracking
The default TCP port used for per-user URL redirect for EAPoUDP,
Dot1x, and MAB is 80 and 443.
Further information about per-user URL redirect for EAPoUDP, Dot1x,
and MAB is in the "Catalyst 4500 Series Switch Software Configuration
Guide, 12.2(50)SG" at the following link
http://www.cisco.com/en/US/docs/switches/lan/catalyst4500/12.2/50sg/configuration/guide/dot1x.html#wp1311079
Distributed Director with HTTP Redirects
+---------------------------------------
A device is vulnerable if Distributed Director is configured with
HTTP redirects. The following example shows a vulnerable
configuration:
ip director ip-address 192.168.0.1
The default TCP port used for distributed director with HTTP redirect
is 53.
Further information about Distributed Director with HTTP redirects is
in "Distributed Director Configuration Example Overview" at the
following link
http://www.cisco.com/en/US/products/hw/contnetw/ps813/products_tech_note09186a00801fa9dd.shtml#topic8b
DNS
+--
Devices that are configured with the Cisco IOS DNS feature are
vulnerable. A pure DNS over UDP implementation is not vulnerable. See
the "Workarounds" section of this advisory for information about
filtering DNS over TCP traffic to the device. If any of the commands
in the following example appear in the device configuration, the
device is vulnerable:
ip dns server
ip dns primary example.com soa www.example.com admin@...mple.com
ip dns spoofing 192.168.0.1
The default TCP port used for DNS is 53.
Further information about Cisco IOS DNS is in the "Cisco IOS IP
Addressing Services Configuration Guide, Release 12.4" at the
following link
http://www.cisco.com/en/US/docs/ios/ipaddr/configuration/guide/iad_config_dns_ps6350_TSD_Products_Configuration_Guide_Chapter.html

Workarounds
===========
The following mitigations have been identified for this
vulnerability:
Infrastructure Access Control Lists
+----------------------------------
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 networks. Infrastructure Access Control Lists (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 these specific vulnerabilities. The iACL example below should be
included as part of the deployed infrastructure access-list which
will protect all devices with IP addresses in the infrastructure IP
address range:
!--- Only sections pertaining to features enabled on the device
!--- need be configured.
!---
!--- Feature: Cisco Unified Communications Manager Express

The white paper entitled "Protecting Your Core: Infrastructure
Protection Access Control Lists" presents guidelines and recommended
deployment techniques for infrastructure protection access lists.
This white paper can be obtained at the following link
http://www.cisco.com/en/US/tech/tk648/tk361/technologies_white_paper09186a00801a1a55.shtml
Receive ACLs (rACL)
+------------------
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_paper09186a00801a0a5e.shtml

Control Plane Policing
+---------------------
Control Plane Policing (CoPP) can be used to block the affected
features TCP traffic access 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 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
which will protect all devices with IP addresses in the
infrastructure IP address range.

In the above CoPP example, the access control list 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
trains:
policy-map drop-tcpip-traffic
class drop-tcpip-class
police 32000 1500 1500 conform-action drop exceed-action drop
