Vulnerability from variot - Updated: 2023-12-18 12:52Unspecified vulnerability in Cisco IOS 12.2SB before 12.2(33)SB10 and 15.0S before 15.0(1)S3a on Cisco 10000 series routers allows remote attackers to cause a denial of service (device reload) via a sequence of crafted ICMP packets, aka Bug ID CSCtk62453. Successful exploits will cause an affected device to reload or hang, denying service to legitimate users. This issue is being tracked by Cisco Bug ID CSCtk62453.
Cisco has released free software updates that address this vulnerability.
Workarounds that mitigate this vulnerability are also available.
This advisory is posted at http://www.cisco.com/warp/public/707/cisco-sa-20110928-c10k.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.
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)

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 Cisco IOS 12.2SB before 12.2(33)SB10 and 15.0S before 15.0(1)S3a on Cisco 10000 series routers allows remote attackers to cause a denial of service (device reload) via a sequence of crafted ICMP packets, aka Bug ID CSCtk62453. \nSuccessful exploits will cause an affected device to reload or hang, denying service to legitimate users. \nThis issue is being tracked by Cisco Bug ID CSCtk62453. \n\nCisco has released free software updates that address this\nvulnerability. \n\nWorkarounds that mitigate this vulnerability are also available. \n\nThis advisory is posted at\nhttp://www.cisco.com/warp/public/707/cisco-sa-20110928-c10k.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\nTo determine the Cisco IOS Software release that is running on a Cisco\nproduct, administrators can log in to the device and issue the \"show\nversion\" 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 \"Cisco\nIOS Software.\" The image name displays in parentheses, followed by\n\"Version\" and the Cisco IOS Software release name. Other Cisco devices\ndo not have the \"show version\" command or may provide different 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 naming\nconventions is available in the white paper Cisco IOS and NX-OS\nSoftware Reference Guide available at:\n\nhttp://www.cisco.com/web/about/security/intelligence/ios-ref.html. \n\nProducts Confirmed Not Vulnerable\n+--------------------------------\n\nCisco IOS XR Software is not affected by this vulnerability. \n\nCisco IOS XE Software is not affected by this vulnerability. \n\nNo other Cisco products are currently known to be affected by this\nvulnerability. \n\nTraffic destined to the device or transit traffic could trigger the\neffects of this vulnerability. \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* CSCtk62453 (\"Certain ICMP packets may cause device to reload\")\n\nCVSS Base Score - 7.8\n Access Vector - Network\n Access Complexity - Low\n Authentication - None\n Confidentiality Impact - None\n Integrity Impact - None\n Availability Impact - Complete\n\nCVSS Temporal Score - 6.4\n Exploitability - Functional\n Remediation Level - Official-Fix\n Report Confidence - Confirmed\n\nImpact\n======\n\nSuccessful exploitation of this vulnerability could cause an affected\ndevice to reload. Repeated exploitation could result in a sustained\nDoS condition. \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. \n\nCisco IOS Software\n+-----------------\n\nEach row of the following Cisco IOS Software table corresponds to a\nCisco IOS Software train. 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 Release for |\n| 12.0-Based | First Fixed | All Advisories in the |\n| Releases | Release | September 2011 Bundled |\n| | | Publication |\n|------------------------------------------------------------|\n| There are no affected 12.0 based releases |\n|------------------------------------------------------------|\n| Affected | | First Fixed Release for |\n| 12.1-Based | First Fixed | All Advisories in the |\n| Releases | Release | September 2011 Bundled |\n| | | Publication |\n|------------------------------------------------------------|\n| There are no affected 12.1 based releases |\n|------------------------------------------------------------|\n| Affected | | First Fixed Release for |\n| 12.2-Based | First Fixed | All Advisories in the |\n| Releases | Release | September 2011 Bundled |\n| | | Publication |\n|------------+------------------+----------------------------|\n| 12.2 | Not vulnerable | Vulnerable;
