      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)

      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.

      ======
      
      Successful exploitation of the vulnerability described in this
      advisory may allow valid but unauthorized 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.
      
      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 at cisco dot com or security-alert at cisco dot 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 at cisco dot 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.
