Vulnerability from variot - Updated: 2025-04-11 23:08Unspecified vulnerability in the Smart Install functionality in Cisco IOS 12.2 and 15.1 allows remote attackers to execute arbitrary code or cause a denial of service (device crash) via crafted TCP packets to port 4786, aka Bug ID CSCto10165. Cisco IOS is prone to a remote code-execution service vulnerability. An attacker can exploit this issue to execute arbitrary code with elevated privileges on affected devices. Successful exploits will completely compromise an affected device. This issue is tracked by Cisco Bug ID CSCto10165. Cisco's Internet Operating System (IOS) is a complex operating system optimized for Internet interconnection.
Cisco has released free software updates that address this vulnerability.
There are no workarounds available to mitigate this vulnerability other than disabling the Smart Install feature.
This advisory is posted at http://www.cisco.com/warp/public/707/cisco-sa-20110928-smart-install.shtml.
Note: The September 28, 2011, Cisco IOS Software Security Advisory bundled publication includes ten 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 September 2011 Bundled Publication.

Affected Products
This vulnerability only affects Cisco Catalyst Switches and Cisco Integrated Services Routers with the Smart Install feature enabled.
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 the show commands are different when entered on the director or on the client. The following is the output of the "show vstack config" in a device 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 the "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)
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 switches and Cisco Integrated Services Routers. This means that a customer can ship a device to a location, place it in the network and power it on with no configuration required on the device. Smart Install uses TCP port 4786 for communication. An established TCP connection with a completed TCP three-way handshake is needed to be able to trigger this vulnerability.
Vulnerability Scoring Details

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.
Additionally, the Cisco IOS Software Checker is available on the Cisco Security Intelligence Operations (SIO) portal at http://tools.cisco.com/security/center/selectIOSVersion.x. It provides several features for checking which Security Advisories affect specified versions of Cisco IOS Software. If a particular train is vulnerable, the earliest releases that contain the fix are listed in the First Fixed Release For This Advisory column. The First Fixed Release for All Advisories in the September 2011 Bundled Publication column lists the earliest possible releases that correct all the published vulnerabilities in the Cisco IOS Software Security Advisory bundled publication. Cisco recommends upgrading to the latest available release, where possible.

Workarounds
There are no workarounds available to mitigate this vulnerability other than disabling the Smart Install feature. The Smart Install Feature is enabled by default in client switches. No configuration is needed in client switches.
If Smart Install feature is not required, and the device supports the configuration command "no vstack" as introduced by Cisco Bug ID CSCtj75729, then disabling Smart Install, with the "no vstack" configuration command mitigates this vulnerability.
Additional mitigations that can be deployed on Cisco devices within the network are available in the Cisco Applied Mitigation Bulletin companion document for this advisory, which is available at the following link:
http://www.cisco.com/warp/public/707/cisco-amb-20110928-smart-install.shtml
Obtaining Fixed Software
Cisco has released free software updates that address this vulnerability. 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.

"data": "Unspecified vulnerability in the Smart Install functionality in Cisco IOS 12.2 and 15.1 allows remote attackers to execute arbitrary code or cause a denial of service (device crash) via crafted TCP packets to port 4786, aka Bug ID CSCto10165. Cisco IOS is prone to a remote code-execution service vulnerability. \nAn attacker can exploit this issue to execute arbitrary code with elevated privileges on affected devices. Successful exploits will completely compromise an affected device. \nThis issue is tracked by Cisco Bug ID CSCto10165. Cisco\u0027s Internet Operating System (IOS) is a complex operating system optimized for Internet interconnection. \n\nCisco has released free software updates that address this\nvulnerability. \n\nThere are no workarounds available to mitigate this vulnerability\nother than disabling the Smart Install feature. \n\nThis advisory is posted at\nhttp://www.cisco.com/warp/public/707/cisco-sa-20110928-smart-install.shtml. \n\nNote: The September 28, 2011, Cisco IOS Software Security Advisory\nbundled publication includes ten Cisco Security Advisories. Each advisory lists the Cisco IOS Software releases that\ncorrect the vulnerability or vulnerabilities detailed in the advisory as\nwell as the Cisco IOS Software releases that correct all vulnerabilities\nin the September 2011 Bundled Publication. \n\nIndividual publication links are in \"Cisco Event Response: Semiannual\nCisco IOS Software Security Advisory Bundled Publication\" at the\nfollowing link:\n\nhttp://www.cisco.com/web/about/security/intelligence/Cisco_ERP_sep11.html\n\nAffected Products\n=================\n\nThis vulnerability only affects Cisco Catalyst Switches and Cisco\nIntegrated Services Routers with the Smart Install feature enabled. \n\nVulnerable Products\n+------------------\n\nDevices configured as a Smart Install client or director are affected\nby this vulnerability. To display Smart Install information, use the\n\"show vstack config\" privileged EXEC command on the Smart Install\ndirector or client. The outputs of the show commands are different\nwhen entered on the director or on the client. The following is the\noutput of the \"show vstack config\" in a device configured as a Smart\nInstall client:\n\n switch#show vstack config\n Role: Client\n Vstack Director IP address: 10.1.1.163\n\nThe following is the output of the \"show vstack config\" in a Cisco\nCatalyst Switch configured as a Smart Install director:\n\n Director# show vstack config\n\n Role: Director\n Vstack Director IP address: 10.1.1.163\n Vstack Mode: Basic\n Vstack default management vlan: 1\n Vstack management Vlans: none\n Vstack Config file: tftp://10.1.1.100/default-config.txt\n Vstack Image file: tftp://10.1.1.100/c3750e-universalk9-tar.122-\n Join Window Details:\n Window: Open (default)\n Operation Mode: auto (default)\n Vstack Backup Details:\n Mode: On (default)\n Repository: flash:/vstack (default)\n\nTo determine the Cisco IOS Software release that is running on a\nCisco product, administrators can log in to the device and issue the\n\"show version\" command to display the system banner. The system banner\nconfirms that the device is running Cisco IOS Software by displaying\ntext similar to \"Cisco Internetwork Operating System Software\" or\n\"Cisco IOS Software.\" The image name displays in parentheses,\nfollowed by \"Version\" and the Cisco IOS Software release name. Other\nCisco devices do not have the \"show version\" command or may provide\ndifferent output. \n\nThe following example identifies a Cisco product that is running\nCisco IOS Software Release 15.0(1)M1 with an installed image name of\nC3900-UNIVERSALK9-M:\n\n Router\u003e show version\n Cisco IOS Software, C3900 Software (C3900-UNIVERSALK9-M), Version 15.0(1)M1, RELEASE SOFTWARE (fc1)\n Technical Support: http://www.cisco.com/techsupport\n Copyright (c) 1986-2009 by Cisco Systems, Inc. \n Compiled Wed 02-Dec-09 17:17 by prod_rel_team\n\n !--- output truncated\n\nAdditional information about Cisco IOS Software release\nnaming conventions is available in the white paper Cisco\nIOS and NX-OS Software Reference Guide available at\nhttp://www.cisco.com/web/about/security/intelligence/ios-ref.html. \n\nDetails\n=======\n\nSmart Install is a plug-and-play configuration and image-management\nfeature that provides zero-touch deployment for new switches and\nCisco Integrated Services Routers. This means that a customer can\nship a device to a location, place it in the network and power it on\nwith no configuration required on the device. Smart Install uses TCP port 4786 for\ncommunication. An established TCP connection with a completed TCP\nthree-way handshake is needed to be able to trigger this\nvulnerability. \n\nVulnerability Scoring Details\n=============================\n\nCisco has provided scores for the vulnerability in this advisory\nbased on the Common Vulnerability Scoring System (CVSS). The CVSS\nscoring in this Security Advisory is done in accordance with CVSS\nversion 2.0. \n\nCVSS is a standards-based scoring method that conveys vulnerability\nseverity and helps determine urgency and priority of response. \n\nCisco has provided a base and temporal score. Customers can then\ncompute environmental scores to assist in determining the impact of\nthe vulnerability in individual networks. \n\nCisco has provided an FAQ to answer additional questions regarding\nCVSS at:\n\nhttp://www.cisco.com/web/about/security/intelligence/cvss-qandas.html\n\nCisco has also provided a CVSS calculator to help compute the\nenvironmental impact for individual networks at:\n\nhttp://intellishield.cisco.com/security/alertmanager/cvss\n\n\n* CSCto10165 (\"Smart Install Crashes with certain IP Packets\")\n\nCVSS Base Score - 10.0\n Access Vector - Network\n Access Complexity - Low\n Authentication - None\n Confidentiality Impact - Complete\n Integrity Impact - Complete\n Availability Impact - Complete\n\nCVSS Temporal Score - 8.3\n Exploitability - Functional\n Remediation Level - Official-Fix\n Report Confidence - Confirmed\n\n\nImpact\n======\n\nSuccessful exploitation could allow an unauthenticated, remote\nattacker to perform remote code execution on the affected device. \n\nSoftware Versions and Fixes\n===========================\n\nWhen considering software upgrades, also consult\nhttp://www.cisco.com/go/psirt and any subsequent advisories to determine\nexposure and a complete upgrade solution. \n\nIn all cases, customers should exercise caution to be certain the\ndevices to be upgraded contain sufficient memory and that current\nhardware and software configurations will continue to be supported\nproperly by the new release. If the information is not clear, contact\nthe Cisco Technical Assistance Center (TAC) or your contracted\nmaintenance provider for assistance. \n\nAdditionally, the Cisco IOS Software Checker is available on\nthe Cisco Security Intelligence Operations (SIO) portal at\nhttp://tools.cisco.com/security/center/selectIOSVersion.x. It provides\nseveral features for checking which Security Advisories affect specified\nversions of Cisco IOS Software. If a particular train is vulnerable, the\nearliest releases that contain the fix are listed in the First Fixed\nRelease For This Advisory column. The First Fixed Release for All\nAdvisories in the September 2011 Bundled Publication column lists the\nearliest possible releases that correct all the published\nvulnerabilities in the Cisco IOS Software Security Advisory bundled\npublication. Cisco recommends upgrading to the latest available\nrelease, where possible. \n\n+------------------------------------------------------------+\n| Major | Availability of Repaired Releases |\n| Release | |\n|------------+-----------------------------------------------|\n| Affected | First Fixed | First Fixed Release for All |\n| 12.0-Based | Release | Advisories in the September |\n| Releases | | 2011 Bundled Publication |\n|------------------------------------------------------------|\n| There are no affected 12.0 based releases |\n|------------------------------------------------------------|\n| Affected | First Fixed | First Fixed Release for All |\n| 12.1-Based | Release | Advisories in the September |\n| Releases | | 2011 Bundled Publication |\n|------------------------------------------------------------|\n| There are no affected 12.1 based releases |\n|------------------------------------------------------------|\n| Affected | First Fixed | First Fixed Release for All |\n| 12.2-Based | Release | Advisories in the September |\n| Releases | | 2011 Bundled Publication |\n|------------+----------------+------------------------------|\n| 12.2 | Not vulnerable | Vulnerable;

The Smart Install\nFeature is enabled by default in client switches. No configuration is\nneeded in client switches. \n\nIf Smart Install feature is not required, and the device supports\nthe configuration command \"no vstack\" as introduced by Cisco Bug\nID CSCtj75729, then disabling Smart Install, with the \"no vstack\"\nconfiguration command mitigates this vulnerability. \n\nAdditional mitigations that can be deployed on Cisco devices within the\nnetwork are available in the Cisco Applied Mitigation Bulletin companion\ndocument for this advisory, which is available at the following link:\n\nhttp://www.cisco.com/warp/public/707/cisco-amb-20110928-smart-install.shtml\n\nObtaining Fixed Software\n========================\n\nCisco has released free software updates that address this\nvulnerability. Prior to deploying software, customers should consult\ntheir maintenance provider or check the software for feature set\ncompatibility and known issues specific to their environment. \n\nCustomers may only install and expect support for the feature\nsets they have purchased. By installing, downloading, accessing\nor otherwise using such software upgrades, customers agree to be\nbound by the terms of Cisco\u0027s software license terms found at\nhttp://www.cisco.com/en/US/docs/general/warranty/English/EU1KEN_.html,\nor as otherwise set forth at Cisco.com Downloads at\nhttp://www.cisco.com/public/sw-center/sw-usingswc.shtml. \n\nDo not contact psirt@cisco.com or security-alert@cisco.com for\nsoftware upgrades. \n\nCustomers with Service Contracts\n+-------------------------------\n\nCustomers with contracts should obtain upgraded software through\ntheir regular update channels. For most customers, this means that\nupgrades should be obtained through the Software Center on Cisco\u0027s\nworldwide website at http://www.cisco.com. \n\nCustomers using Third Party Support Organizations\n+------------------------------------------------\n\nCustomers whose Cisco products are provided or maintained through\nprior or existing agreements with third-party support organizations,\nsuch as Cisco Partners, authorized resellers, or service providers\nshould contact that support organization for guidance and assistance\nwith the appropriate course of action in regards to this advisory. \n\nThe effectiveness of any workaround or fix is dependent on specific\ncustomer situations, such as product mix, network topology, traffic\nbehavior, and organizational mission. Due to the variety of affected\nproducts and releases, customers should consult with their service\nprovider or support organization to ensure any applied workaround or\nfix is the most appropriate for use in the intended network before it\nis deployed. \n\nCustomers without Service Contracts\n+----------------------------------\n\nCustomers who purchase direct from Cisco but do not hold a Cisco\nservice contract, and customers who purchase through third-party\nvendors but are unsuccessful in obtaining fixed software through\ntheir point of sale should acquire upgrades by contacting the Cisco\nTechnical Assistance Center (TAC). TAC contacts are as follows. \n\n * +1 800 553 2447 (toll free from within North America)\n * +1 408 526 7209 (toll call from anywhere in the world)\n * e-mail: tac@cisco.com\n\nCustomers should have their product serial number available and be\nprepared to give the URL of this notice as evidence of entitlement to\na free upgrade. Free upgrades for non-contract customers must be\nrequested through the TAC. \n\nRefer to\nhttp://www.cisco.com/en/US/support/tsd_cisco_worldwide_contacts.html\nfor additional TAC contact information, including localized telephone\nnumbers, and instructions and e-mail addresses for use in various\nlanguages. \n\nExploitation and Public Announcements\n=====================================\n\nThe Cisco PSIRT is not aware of any public announcements or malicious\nuse of the vulnerability described in this advisory. \n\nThis vulnerability was discovered and reported to Cisco by Greg Jones\nof Digital Assurance. \n\nStatus of this Notice: FINAL\n============================\n\nTHIS DOCUMENT IS PROVIDED ON AN \"AS IS\" BASIS AND DOES NOT IMPLY ANY\nKIND OF GUARANTEE OR WARRANTY, INCLUDING THE WARRANTIES OF\nMERCHANTABILITY OR FITNESS FOR A PARTICULAR USE.
