Cisco Security Advisory: Cisco IOS Software Secure Copy Privilege
Escalation Vulnerability

Advisory ID: cisco-sa-20090325-scp

http://www.cisco.com/warp/public/707/cisco-sa-20090325-scp.shtml

Revision 1.0

For Public Release 2009 March 25 1600 UTC (GMT)

- ---------------------------------------------------------------------

Summary
=======

The server side of the Secure Copy (SCP) implementation in Cisco IOS
software contains a vulnerability that could allow authenticated
users with an attached command-line interface (CLI) view to transfer
files to and from a Cisco IOS device that is configured to be an SCP
server, regardless of what users are authorized to do, per the CLI
view configuration. This vulnerability could allow valid users to
retrieve or write to any file on the device's file system, including
the device's saved configuration and Cisco IOS image files, even if
the CLI view attached to the user does not allow it. This
configuration file may include passwords or other sensitive
information.

The Cisco IOS SCP server is an optional service that is disabled by
default. CLI views are a fundamental component of the Cisco IOS
Role-Based CLI Access feature, which is also disabled by default.
Devices that are not specifically configured to enable the Cisco IOS
SCP server, or that are configured to use it but do not use
role-based CLI access, are not affected by this vulnerability.

This vulnerability does not apply to the Cisco IOS SCP client
feature.

Cisco has released free software updates that address this
vulnerability.

There are no workarounds available for this vulnerability apart from
disabling either the SCP server or the CLI view feature if these
services are not required by administrators.

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

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

Cisco devices running an affected Cisco IOS software release,
configured to offer SCP server functionality, and configured to use
role-based ACL access are affected by this issue.

A device running a vulnerable Cisco IOS software release is affected
if its configuration is similar to the following:

    parser view <view name>
     <Definition of the CLI view>
    !
    username <user ID> view <view name> secret <some secret>
    !
    ip scp server enable

In the above configuration snippet, the parser view command defines a
view that specifies what commands users in that view can execute. The
username command defines a local user and attaches, via the view
keyword, the previously defined view to the user. And finally, the ip
scp server enable command enables the Cisco IOS SCP server.

The absence of the username command does not guarantee that the
device's configuration is not affected by this vulnerability because
the name of a CLI view can be supplied by means of an Authentication,
Authorization, and Accounting (AAA) server by using the cli-view-name
attribute.

Note: The CLI view attached to a user can be supplied by a AAA
server. When inspecting a device's configuration to determine if it
is affected by this vulnerability it is better to check if the SCP
service is enabled (ip scp server enabled command) and whether there
are any CLI views defined (parser view command).

The Cisco IOS SCP server and role-based CLI access features are
disabled by default.

The SCP server functionality is only available on encryption-capable
images. Encryption-capable images are those that contain either a
"k8" or "k9" in the image name, for example, "C7200-ADVSECURITYK9-M".
Devices that do not run encryption-capable images are not vulnerable.
If a device is running an encryption-capable image, the presence in
the configuration of the ip scp server enable command, the existence
of CLI views (parser view command), and whether there are users
(local or remote) attached to these views will determine if the
device is affected.

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:

    Router#show version
    Cisco Internetwork Operating System Software
    IOS (tm) 2500 Software (C2500-IS-L), Version 12.3(26), RELEASE SOFTWARE (fc2)

Additional information about Cisco IOS Software release naming
conventions is available in "White Paper: Cisco IOS Reference Guide"
at the following link: http://www.cisco.com/warp/public/620/1.html

Cisco IOS XE Software is also affected by this vulnerability.

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

Cisco devices that do not run Cisco IOS software are not affected.

Cisco IOS devices that do not have the SCP server feature enabled, or
that make use of the feature but do not have the role-based CLI
feature enabled, are not affected.

Cisco IOS XR Software is not affected.

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

Details
=======

SCP is a protocol similar to the Remote Copy (RCP) protocol, which
allows the transfer of files between systems. The main difference
between SCP and RCP is that in SCP, all aspects of the file transfer
session, including authentication, occur in encrypted form, which
makes SCP a more secure alternative than RCP. SCP relies on the
Secure Shell (SSH) protocol, which uses TCP port 22 by default.

The Role-Based CLI Access feature allows the network administrator to
define "views". Views are sets of operational commands and
configuration capabilities that provide selective or partial access
to Cisco IOS software EXEC and configuration (Config) mode commands.
Views restrict user access to Cisco IOS command-line interface (CLI)
and configuration information; that is, a view can define what
commands are accepted and what configuration information is visible.
For more information about the Role-Based CLI Access feature,
reference 
http://www.cisco.com/en/US/docs/ios/12_3t/12_3t7/feature/guide/gtclivws.html

The server side of the SCP implementation in Cisco IOS software
contains a vulnerability that allows authenticated users with an
attached command-line interface (CLI) view to transfer files to and
from a Cisco IOS device that is configured to be a SCP server,
regardless of what users are authorized to do, per the CLI view
configuration. This vulnerability could allow authenticated users to
retrieve or write to any file on the device's file system, including
the device's saved configuration and Cisco IOS image files. This
configuration file may include passwords or other sensitive
information.

In the affected configuration presented in the Affected Products
section, users confined to a CLI view can elevate their privileges by
using SCP to write to the device's configuration. Note that a view
can be attached to a user when defining the user in the local
database (via the username <user name> view ... command), or by
passing the attribute cli-view-name from an AAA server.

This vulnerability does not allow for authentication bypass; login
credentials are verified and access is only granted if a valid
username and password is provided. This vulnerability may cause
authorization to be bypassed.

This vulnerability is documented in the Cisco Bug ID CSCsv38166 
and has been assigned Common Vulnerabilities and Exposures (CVE) ID
CVE-2009-0637.

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
===========

If the Cisco IOS SCP server functionality is not needed then the
vulnerability described in this document can be mitigated by
disabling the SCP server or the CLI view feature. The SCP server can
be disabled by executing the following command in global
configuration mode:

    no ip scp server enable

If the SCP server cannot be disabled due to operational concerns,
then no workarounds exist. The risk posed by this vulnerability can
be mitigated by following the best practices detailed in "Cisco Guide
to Harden Cisco IOS Devices" at 
http://www.cisco.com/en/US/tech/tk648/tk361/technologies_tech_note09186a0080120f48.shtml
Please refer to the Obtaining Fixed Software section of this advisory
for appropriate solutions to resolve this vulnerability.

Due to the nature of this vulnerability, networking best practices
like access control lists (ACLs) and Control Plane Policing (CoPP)
that restrict access to a device to certain IP addresses or
subnetworks may not be effective. If access is already granted to a
specific IP address or subnetwork, a user with low privileges will be
able to establish an SCP session with the device, which would allow
the user to exploit this vulnerability.

Obtaining Fixed Software
========================

Cisco has released free software updates that address these
vulnerabilities. Prior to deploying software, customers should
consult their maintenance provider or check the software for feature
set compatibility and known issues specific to their environment.

Customers may only install and expect support for the feature sets
they have purchased. By installing, downloading, accessing or
otherwise using such software upgrades, customers agree to be bound
by the terms of Cisco's software license terms found at 
http://www.cisco.com/en/US/docs/general/warranty/English/EU1KEN_.html, or as
otherwise set forth at Cisco.com Downloads at 
http://www.cisco.com/public/sw-center/sw-usingswc.shtml

Do not contact psirt () cisco com or security-alert () cisco com for
software upgrades.

Customers with Service Contracts
+-------------------------------

Customers with contracts should obtain upgraded software through
their regular update channels. For most customers, this means that
upgrades should be obtained through the Software Center on Cisco's
worldwide website at http://www.cisco.com

Customers using Third Party Support Organizations
+------------------------------------------------

Customers whose Cisco products are provided or maintained through
prior or existing agreements with third-party support organizations,
such as Cisco Partners, authorized resellers, or service providers
should contact that support organization for guidance and assistance
with the appropriate course of action in regards to this advisory.

The effectiveness of any workaround or fix is dependent on specific
customer situations, such as product mix, network topology, traffic
behavior, and organizational mission. Due to the variety of affected
products and releases, customers should consult with their service
provider or support organization to ensure any applied workaround or
fix is the most appropriate for use in the intended network before it
is deployed.

Customers without Service Contracts
+----------------------------------

Customers who purchase direct from Cisco but do not hold a Cisco
service contract, and customers who purchase through third-party
vendors but are unsuccessful in obtaining fixed software through
their point of sale should acquire upgrades by contacting the Cisco
Technical Assistance Center (TAC). TAC contacts are as follows.

  * +1 800 553 2447 (toll free from within North America)
  * +1 408 526 7209 (toll call from anywhere in the world)
  * e-mail: tac () cisco com

Customers should have their product serial number available and be
prepared to give the URL of this notice as evidence of entitlement to
a free upgrade. Free upgrades for non-contract customers must be
requested through the TAC.

Refer to http://www.cisco.com/en/US/support/tsd_cisco_worldwide_contacts.html
for additional TAC contact information, including localized telephone 
numbers, and instructions and e-mail addresses for use in various 
languages.
