Cisco Security Advisory: Cisco IOS Software Command Authorization Bypass
Advisory ID: cisco-sa-20120328-pai
Revision 1.0
For Public Release 2012 March 28 16:00 UTC (GMT)
+---------------------------------------------------------------------
Summary
=======
A vulnerability exists in the Cisco IOS Software that may allow a
remote application or device to exceed its authorization level when
authentication, authorization, and accounting (AAA) authorization is
used. This vulnerability requires that the HTTP or HTTPS server is
enabled on the Cisco IOS device.
Products that are not running Cisco IOS Software are not vulnerable.
Cisco has released free software updates that address these
vulnerabilities.
The HTTP server may be disabled as a workaround for the vulnerability
described in this advisory.
This advisory is available at the following link:
http://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20120328-pai
Note: The March 28, 2012, Cisco IOS Software Security Advisory
bundled publication includes nine Cisco Security Advisories. Each
advisory lists the Cisco IOS Software releases that correct the
vulnerability or vulnerabilities detailed in the advisory as well as
the Cisco IOS Software releases that correct all vulnerabilities in
the March 2012 bundled publication.
Individual publication links are in "Cisco Event Response:
Semi-Annual Cisco IOS Software Security Advisory Bundled Publication"
at the following link:
http://www.cisco.com/web/about/security/intelligence/Cisco_ERP_mar12.html
Affected Products
=================
Vulnerable Products
+------------------
Any device running Cisco IOS Software release after 12.2 that has an
HTTP or HTTPS server configured is affected by this vulnerability if
AAA authorization is used.
To determine if an HTTP or HTTP server is configured with an HTTP or
HTTPS server, issue the show ip http server status | include status
command. The following example illustrates a Cisco IOS device with an
HTTPS server enabled and the HTTP server disabled.
Router> show ip http server status | include status
HTTP server status: Disabled
HTTP secure server status: Enabled
To determine if AAA authorization is used, an administrator can log
in to the device and issue the show run | include aaa authorization
command in privileged EXEC mode. If there is an entry that shows aaa
authorization commands, as shown in the following example, then AAA
authorization is configured.
Router# show run | include aaa authorization commands
aaa authorization commands 0 default local group tacacs+
aaa authorization commands 1 default group tacacs+
aaa authorization commands 15 default local
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 15.0(1)M1 with an installed image name of
C3900-UNIVERSALK9-M:
Router> show version
Cisco IOS Software, C3900 Software (C3900-UNIVERSALK9-M), Version 15.0(1)M1,
RELEASE SOFTWARE (fc1)

Products Confirmed Not Vulnerable
+--------------------------------
If you are not running Cisco IOS or IOS XE software, you are not
affected by this vulnerability. Devices that are not using AAA
authorization or that do not have an HTTP or HTTPS server configured
are not affected by this vulnerability.
Cisco IOS XR is not affected by this vulnerability.
No other Cisco products are currently known to be affected by this
vulnerability.
Details
=======
Cisco IOS allows remote applications to administer and monitor
devices running Cisco IOS Software over an HTTP or HTTPS connection.
A vulnerability exists that may allow the Cisco IOS command
authorization to be bypassed, allowing a remote, authenticated HTTP
or HTTPS session to execute any Cisco IOS command that is configured
for their authorization level. This vulnerability does not allow
unauthenticated access; a valid username and password are required to
successfully exploit this vulnerability. Additionally, the
vulnerability does not allow a user to execute commands that are not
configured for their privilege level.
The HTTP server is enabled by default for cluster configurations and
on the following Cisco switches: Catalyst 3700 series, Catalyst 3750
series, Catalyst 3550 series, Catalyst 3560 series, and Catalyst 2950
series.
More information on AAA authorization can be found at:
http://www.cisco.com/en/US/docs/ios/12_2t/secure/command/reference/sftauth.html
Releases of Cisco IOS Software after release 12.2 are potentially
vulnerable. Please refer to the release table below for more
information.
This vulnerability is documented as Cisco Bug ID CSCtr91106
and has been assigned Common Vulnerabilities and Exposures (CVE) ID
CVE-2012-0384.
Vulnerability Scoring Details
=============================
Cisco has scored the vulnerability in this advisory based on the
Common Vulnerability Scoring System (CVSS). The CVSS scoring in this
security advisory is in accordance with CVSS version 2.0.
CVSS is a standards-based scoring method that conveys vulnerability
severity and helps organizations determine the urgency and priority
of a response.

Cisco has provided additional information regarding CVSS at the
following link:
http://www.cisco.com/web/about/security/intelligence/cvss-qandas.html
Cisco has also provided a CVSS calculator to compute the
environmental impact for individual networks at the following link:
http://intellishield.cisco.com/security/alertmanager/cvss
* Command Authorization Fails for commands delivered over HTTP
CVSS Base Score - 8.5
Access Vector - Network
Access Complexity - Medium
Authentication - None
Confidentiality Impact - Complete
Integrity Impact - Complete
Availability Impact - Complete
CVSS Temporal Score - 7.0
Exploitability - Functional
Remediation Level - Official-Fix
Report Confidence - Confirmed
Impact
======
Successful exploitation of the vulnerability may allow the Cisco IOS
command authorization to be bypassed, allowing a remote,
authenticated HTTP or HTTPS session to execute any Cisco IOS command
that is configured for its authorization level.
Software Versions and Fixes
===========================
When considering software upgrades, customers are advised to consult
the Cisco Security Advisories and Responses archive at:
http://www.cisco.com/go/psirt and review subsequent advisories to determine
exposure and a complete upgrade solution.
In all cases, customers should ensure that the devices to be upgraded
contain sufficient memory and confirm that current hardware and
software configurations will continue to be supported properly by the
new release. If the information is not clear, customers are advised
to contact the Cisco Technical Assistance Center (TAC) or their
contracted maintenance providers.

Cisco IOS XR Software
+--------------------
Cisco IOS XR Software is not affected by any of the vulnerabilities
disclosed in the March 2012 Cisco IOS Software Security Advisory
Bundled Publication.
Workarounds
===========
If the HTTP and HTTPS servers are not required, they may be disabled
with the commands no ip http server and no ip http secure-server.
However, if web services are required, a feature was introduced in
12.3(14)T and later in which selective HTTP and HTTPS services could
be enabled or disabled. The WEB_EXEC service provides a facility to
configure the device and retrieve the current state of the device
from remote clients.
It is possible to disable the WEB_EXEC service while still leaving
other HTTP services active. If an installation does not require the
use of the WEB_EXEC service, then it may be disabled using the
following procedure:
1. Verify the list of all session modules.
Router# show ip http server session-module
HTTP server application session modules:
Session module Name Handle Status Secure-status Description
HTTP_IFS 1 Active Active HTTP based IOS File
Server
HOME_PAGE 2 Active Active IOS Homepage
Server
QDM 3 Active Active QOS Device Manager
Server
QDM_SA 4 Active Active QOS Device Manager
Signed Applet Server
WEB_EXEC 5 Active Active HTTP based IOS EXEC
Server
IXI 6 Active Active IOS XML Infra
Application Server
IDCONF 7 Active Active IDCONF HTTP(S)
Server
XSM 8 Active Active XML Session
Manager
VDM 9 Active Active VPN Device Manager
Server
XML_Api 10 Active Active XML Api
ITS 11 Active Active IOS Telephony
Service
ITS_LOCDIR 12 Active Active ITS Local Directory
Search
CME_SERVICE_URL 13 Active Active CME Service URL
CME_AUTH_SRV_LOGIN 14 Active Active CME Authentication
Server
IPS_SDEE 15 Active Active IOS IPS SDEE
Server
tti-petitioner 16 Active Active TTI Petitioner
2. Create a list of session modules that are required, in this
example it would be everything other than WEB_EXEC.
Router# configuration terminal
Router(config)# ip http session-module-list exclude_webexec
HTTP_IFS,HOME_PAGE,QDM,QDM_SA,IXI,IDCONF,XSM,VDM,XML_Api,
ITS,ITS_LOCDIR,CME_SERVICE_URL,CME_AUTH_SRV_LOGIN,IPS_SDEE,tti-petitioner
3. Selectively enable HTTP/HTTPS applications that will service
incoming HTTP requests from remote clients.
Router(config)# ip http active-session-modules exclude_webexec
Router(config)# ip http secure-active-session-modules exclude_webexec
Router(config)# exit
4. Verify the list of all session modules, and ensure WEB_EXEC is
not active.
Router# show ip http server session-module
HTTP server application session modules:
Session module Name Handle Status Secure-status Description
HTTP_IFS 1 Active Active HTTP based IOS File
Server
HOME_PAGE 2 Active Active IOS Homepage Server
QDM 3 Active Active QOS Device Manager
Server
QDM_SA 4 Active Active QOS Device Manager
Signed Applet Server
WEB_EXEC 5 Inactive Inactive HTTP based IOS EXEC
Server
IXI 6 Active Active IOS XML Infra
Application Server
IDCONF 7 Active Active IDCONF HTTP(S)
Server
XSM 8 Active Active XML Session Manager
VDM 9 Active Active VPN Device Manager
Server
XML_Api 10 Active Active XML Api
ITS 11 Active Active IOS Telephony
Service
ITS_LOCDIR 12 Active Active ITS Local Directory
Search
CME_SERVICE_URL 13 Active Active CME Service URL
CME_AUTH_SRV_LOGIN 14 Active Active CME Authentication
Server
IPS_SDEE 15 Active Active IOS IPS SDEE Server
tti-petitioner 16 Active Active TTI Petitioner
For further information on the selective enabling of applications
using an HTTP or secure HTTP server, consult the Cisco IOS network
management configuration guide, release 12.4T, at:
http://www.cisco.com/en/US/docs/ios/netmgmt/configuration/guide/nm_http_app_enable.html
If the HTTP server and WEB_EXEC service are required, it is a
recommended best practice to limit which hosts may access the HTTP
server to allow only trusted sources. An access list can be applied
to the HTTP server to limit which hosts are permitted access. To
apply an access list to the HTTP server, use the following command in
global configuration mode: ip http access-class {access-list-number |
access-list-name}.
The following example shows an access list that allows only trusted
hosts to access the Cisco IOS HTTP server:
ip access-list standard 20
permit 192.168.1.0 0.0.0.255
remark "Above is a trusted subnet"
remark "Add further trusted subnets or hosts below"
! (Note: all other access implicitly denied)
! (Apply the access-list to the http server)
ip http access-class 20
For additional information on configuring the Cisco IOS HTTP server,
consult Using the Cisco Web Browser User Interface.
