      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:

      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.

      * Cisco Catalyst 3550 Series Switches support the Internet Key
      Exchange (IKE) feature and are vulnerable to Cisco bug ID CSCts38429
      when the devices are running Layer 3 images; however, this product
      reached the End of Software Maintenance milestone.  Cisco 3550 Series
      SMI Switches that are running Layer 2 images do not support IKE and
      are not vulnerable.  No other Cisco devices that run 12.2SE-based
      software are vulnerable.

      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

      consult Using the Cisco Web Browser User Interface.
