      +---------------------------------------------------------------------
      
      Summary
      =======
      
      Cisco IOS Software contains a vulnerability in the Smart Install
      feature that could allow an unauthenticated, remote attacker to cause
      a reload of an affected device if the Smart Install feature is
      enabled. The vulnerability is triggered when an affected device
      processes a malformed Smart Install message on TCP port 4786.
      
      Cisco has released free software updates that address this
      vulnerability. There are no workarounds to mitigate this
      vulnerability.
      
      This advisory is available at the following link:
      
      http://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20120328-smartinstall

      Affected Products
      =================
      
      Vulnerable Products
      +------------------
      
      Devices configured as a Smart Install client or director are affected
      by this vulnerability. To display Smart Install information, use the 
      show vstack config privileged EXEC command on the Smart Install
      director or client. The outputs of show commands are different when
      entered on the director or on the client. The following is the output
      of show vstack config in a Cisco Catalyst Switch configured as a
      Smart Install client:
      
          switch#show vstack config
           Role: Client
           Vstack Director IP address: 10.1.1.163
      
      The following is the output of show vstack config in a Cisco Catalyst
      Switch configured as a Smart Install director:
      
          Director# show vstack config
          
          Role: Director
           Vstack Director IP address: 10.1.1.163
           Vstack Mode: Basic
           Vstack default management vlan: 1
           Vstack management Vlans: none
           Vstack Config file: tftp://10.1.1.100/default-config.txt
           Vstack Image file: tftp://10.1.1.100/c3750e-universalk9-tar.122-
           Join Window Details:
                   Window: Open (default)
                   Operation Mode: auto (default)
           Vstack Backup Details:
                   Mode: On (default)
                   Repository: flash:/vstack (default)
      
      The Smart Install Feature is enabled by default.
      
      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)

      Details
      =======
      
      Smart Install is a plug-and-play configuration and image-management
      feature that provides zero-touch deployment for new LAN Ethernet
      switches. This feature allows, for example, new LAN switches to be
      deployed at new locations without any configuration.
      
      A vulnerability exists in the Smart Install feature of Cisco IOS
      Software that could allow an unauthenticated, remote attacker to
      cause a reload of an affected device. Smart Install uses a Cisco
      proprietary protocol that runs over TCP port 4786. To exploit this
      vulnerability, an attacker needs to establish a TCP session on port
      4786 of an affected device that has the Smart Install feature
      enabled, and then send a malformed Smart Install message.
      
      This vulnerability is documented in Cisco bug ID CSCtt16051
      and has been assigned Common Vulnerabilities and Exposures (CVE) 
      ID CVE-2012-0385.

      Customers with Cisco products that 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 organization for assistance with the appropriate
      course of action.
      
      The effectiveness of any workaround or fix depends on specific
      customer situations, such as product mix, network topology, traffic
      behavior, and organizational mission. Because of the variety of
      affected products and releases, customers should consult their
      service providers or support organizations to ensure that any applied
      workaround or fix is the most appropriate in the intended network
      before it is deployed.
      
      Customers Without Service Contracts
      +----------------------------------
      
      Customers who purchase directly from Cisco but do not hold a Cisco
      service contract and customers who make purchases through third-party
      vendors but are unsuccessful in obtaining fixed software through
      their point of sale should obtain upgrades by contacting the Cisco
      Technical Assistance Center (TAC):

      Customers should have the product serial number available and be
      prepared to provide the URL of this advisory as evidence of
