Vulnerability from variot
The SSHv2 implementation in Cisco IOS 12.2, 12.4, 15.0, 15.1, and 15.2 and IOS XE 2.3.x through 2.6.x and 3.1.xS through 3.4.xS before 3.4.2S allows remote attackers to cause a denial of service (device reload) via a crafted username in a reverse SSH login attempt, aka Bug ID CSCtr49064. Cisco IOS is a popular Internet operating system. An attacker can exploit this issue to cause a denial-of-service condition. This issue is being tracked by Cisco Bug ID CSCtr49064.
For more information: SA48609
The vulnerability is reported in versions 2.3.x, 2.4.x, 2.5.x, 2.6.x, 3.1.xS, 3.2.xS, and 3.3.xS. Repeated exploits could create a sustained DoS condition. Devices that are not configured to accept SSHv2 connections are not affected by this vulnerability.
Cisco has released free software updates that address this vulnerability. This advisory is available at the following link: http://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20120328-ssh
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. Only SSHv2 is affected.
To determine if SSH is enabled, use the show ip ssh command.
Router#show ip ssh
SSH Enabled - version 2.0
Authentication timeout: 120 secs; Authentication retries: 3
The previous output shows that SSH is enabled on this device and that
the SSH protocol major version that is being supported is 2.0.
Possible values for the SSH protocol versions that are reported by
Cisco IOS are:
- 1.5: only SSH protocol version 1 is enabled
- 1.99: SSH protocol version 2 with SSH protocol version 1 compatibility enabled
- 2.0: only SSH protocol version 2 is enabled
The SSH server is not available in all IOS images. If the show ip ssh command is not available, the device is not vulnerable. Devices that do not support SSHv2 are not vulnerable.
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. 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) Technical Support: http://www.cisco.com/techsupport Copyright (c) 1986-2009 by Cisco Systems, Inc. Compiled Wed 02-Dec-09 17:17 by prod_rel_team !--- output truncated
Additional information about Cisco IOS Software release naming conventions is available in "White Paper: Cisco IOS and NX-OS Software Reference Guide" at: http://www.cisco.com/web/about/security/intelligence/ios-ref.html
Products Confirmed Not Vulnerable +--------------------------------
Cisco IOS-XR is not affected by this vulnerability.
No other Cisco products are currently known to be affected by this vulnerability.
Details
Secure Shell (SSH) is a protocol which provides a secure remote access connection to network devices. Repeated exploits could create a sustained DoS condition. SSH can be configured as part of the AutoSecure feature in the initial configuration of IOS devices, AutoSecure run after initial configuration, or manually. SSH is enabled any time RSA keys are generated such as when an http secure-server or trust points for digital certificates are configured. Devices that are not configured to accept SSHv2 connections are not affected by this vulnerability.
A complete TCP three-way handshake is required to exploit this vulnerability. Reverse SSH traffic uses TCP port 22 by default.
Vulnerability Scoring Details
Cisco has scored the vulnerability in this advisory based on the Common Vulnerability Scoring System (CVSS). The CVSS scoring in this security advisory is in accordance with CVSS version 2.0.
CVSS is a standards-based scoring method that conveys vulnerability severity and helps organizations determine the urgency and priority of a response.
Cisco has provided a base and temporal score. Customers can also compute environmental scores that help determine the impact of the vulnerability in their own networks.
Cisco has provided additional information regarding CVSS at the following link:
http://www.cisco.com/web/about/security/intelligence/cvss-qandas.html
Cisco has also provided a CVSS calculator to compute the environmental impact for individual networks at the following link:
http://intellishield.cisco.com/security/alertmanager/cvss
- CSCtr49064 - Cisco IOS Software Reverse SSH Denial of Service
CVSS Base Score - 7.8 Access Vector - Network Access Complexity - Low Authentication - None Confidentiality Impact - None Integrity Impact - None Availability Impact - Complete
CVSS Temporal Score - 6.4 Exploitability - Functional Remediation Level - Official-Fix Report Confidence - Confirmed
Impact
Successful exploitation of this vulnerability could allow an unauthenticated, remote attacker to create a DoS condition by causing the device to reload. Repeated exploits could create a sustained DoS condition.
Software Versions and Fixes
When considering software upgrades, customers are advised to consult the Cisco Security Advisories and Responses archive at: http://www.cisco.com/go/psirt and review subsequent advisories to determine exposure and a complete upgrade solution.
In all cases, customers should ensure that the devices to be upgraded contain sufficient memory and confirm that current hardware and software configurations will continue to be supported properly by the new release. If the information is not clear, customers are advised to contact the Cisco Technical Assistance Center (TAC) or their contracted maintenance providers. If a particular train is vulnerable, the earliest releases that contain the fix are listed in the First Fixed Release column. The First Fixed Release for All Advisories in the March 2012 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. This tool is available on the Cisco Security Intelligence Operations (SIO) portal at: http://tools.cisco.com/security/center/selectIOSVersion.x

- 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.

Workarounds
If disabling the IOS SSH Server is not feasible, the following workarounds may be useful to some customers in their environments.
SSH version 1 +------------
This vulnerability only affects SSHv2, so it can be temporarily mitigated by applying the ip ssh version 1 global configuration command until a software update can be completed. Customers should be aware of the limitations and vulnerabilities of SSH version 1 protocol before applying this workaround.
vty Access Class +---------------
It is possible to limit the exposure of the Cisco device by applying a vty access class to allow only known, trusted hosts to connect to the device via SSH.
For more information on restricting traffic to a vty, please consult: http://www.cisco.com/en/US/docs/ios/12_2/ipaddr/command/reference/1rfip1.html#wp1017389
The following example permits access to the vty lines from the 192.168.1.0/24 netblock and the single IP address 172.16.1.2 while denying access from anywhere else:
Router(config)# access-list 1 permit 192.168.1.0 0.0.0.255 Router(config)# access-list 1 permit host 172.16.1.2 Router(config)# line vty 0 4 Router(config-line)# access-class 1 in
Different Cisco platforms support a different amount of terminal lines. Check your device's configuration to determine the correct number of terminal lines for your platform.
Infrastructure Access Control Lists +----------------------------------
Although it is often difficult to block traffic transiting your network, it is possible to identify traffic that should never be allowed to target your infrastructure devices and block that traffic at the border of your network. Infrastructure access control lists (iACLs) are considered a network security best practice and should be considered as a long-term addition to good network security as well as a workaround for this specific vulnerability. The ACL example shown below should be included as part of the deployed infrastructure access-list, which will protect all devices with IP addresses in the infrastructure IP address range.
A sample access list for devices running Cisco IOS is below:
!--- Permit SSH services from trusted hosts destined
!--- to infrastructure addresses.
access-list 150 permit tcp TRUSTED_HOSTS MASK INFRASTRUCTURE_ADDRESSES MASK eq 22
!--- Deny SSH packets from all other sources destined to infrastructure addresses.
access-list 150 deny tcp any INFRASTRUCTURE_ADDRESSES MASK eq 22
!--- Permit all other traffic to transit the device.
access-list 150 permit IP any any
interface serial 2/0
ip access-group 150 in
The white paper titled "Protecting Your Core: Infrastructure Protection Access Control Lists" presents guidelines and recommended deployment techniques for infrastructure protection access lists. This white paper is located at: http://www.cisco.com/en/US/tech/tk648/tk361/technologies_white_paper09186a00801a1a55.shtml
Control Plane Policing +---------------------
The Control Plane Policing (CoPP) feature may be used to mitigate these vulnerabilities. In the following example, only SSH traffic from trusted hosts with receive destination IP addresses is permitted to reach the route processor (RP).
Note: Dropping traffic from unknown or untrusted IP addresses may affect hosts with dynamically assigned IP addresses from connecting to the Cisco IOS device.
access-list 152 deny tcp TRUSTED_ADDRESSES MASK any eq 22
access-list 152 permit tcp any any eq 22
!
class-map match-all COPP-KNOWN-UNDESIRABLE
match access-group 152
!
!
policy-map COPP-INPUT-POLICY
class COPP-KNOWN-UNDESIRABLE
drop
!
control-plane
service-policy input COPP-INPUT-POLICY
In the above CoPP example, the ACL entries that match the exploit packets with the permit action result in these packets being discarded by the policy-map drop function, while packets that match the deny action are not affected by the policy-map drop function.
Additional information on the configuration and use of the CoPP feature can be found at the following URL: http://www.cisco.com/en/US/prod/collateral/iosswrel/ps6537/ps6586/ps6642/prod_white_paper0900aecd804fa16a.html

Customers Using Third-Party Support Organizations +------------------------------------------------
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):

"data": "The SSHv2 implementation in Cisco IOS 12.2, 12.4, 15.0, 15.1, and 15.2 and IOS XE 2.3.x through 2.6.x and 3.1.xS through 3.4.xS before 3.4.2S allows remote attackers to cause a denial of service (device reload) via a crafted username in a reverse SSH login attempt, aka Bug ID CSCtr49064. Cisco IOS is a popular Internet operating system. \nAn attacker can exploit this issue to cause a denial-of-service condition. \nThis issue is being tracked by Cisco Bug ID CSCtr49064. \n\nFor more information:\nSA48609\n\nThe vulnerability is reported in versions 2.3.x, 2.4.x, 2.5.x, 2.6.x,\n3.1.xS, 3.2.xS, and 3.3.xS. Repeated exploits\ncould create a sustained DoS condition. Devices that\nare not configured to accept SSHv2 connections are not affected by\nthis vulnerability. \n\nCisco has released free software updates that address this\nvulnerability. This advisory is available at the following link: \nhttp://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20120328-ssh\n\nNote: The March 28, 2012, Cisco IOS Software Security Advisory\nbundled publication includes nine Cisco Security Advisories. Each\nadvisory lists the Cisco IOS Software releases that correct the\nvulnerability or vulnerabilities detailed in the advisory as well as\nthe Cisco IOS Software releases that correct all vulnerabilities in\nthe March 2012 bundled publication. Only SSHv2 is affected. \n\nTo determine if SSH is enabled, use the show ip ssh command. \n Router#show ip ssh \n SSH Enabled - version 2.0 \n Authentication timeout: 120 secs; Authentication retries: 3\nThe previous output shows that SSH is enabled on this device and that\nthe SSH protocol major version that is being supported is 2.0. \nPossible values for the SSH protocol versions that are reported by\nCisco IOS are: \n\n * 1.5: only SSH protocol version 1 is enabled \n * 1.99: SSH protocol version 2 with SSH protocol version 1\n compatibility enabled \n * 2.0: only SSH protocol version 2 is enabled \n\nThe SSH server is not available in all IOS images. If the show ip ssh\n command is not available, the device is not vulnerable. Devices that\ndo not support SSHv2 are not vulnerable. \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 \nshow version command to display the system banner. 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\nRouter\u003e show version \nCisco IOS Software, C3900 Software (C3900-UNIVERSALK9-M), Version 15.0(1)M1, RELEASE SOFTWARE (fc1)\nTechnical Support: http://www.cisco.com/techsupport\nCopyright (c) 1986-2009 by Cisco Systems, Inc. \nCompiled Wed 02-Dec-09 17:17 by prod_rel_team\n!--- output truncated \n\nAdditional information about Cisco IOS Software release naming\nconventions is available in \"White Paper: Cisco IOS and NX-OS\nSoftware Reference Guide\" at:\nhttp://www.cisco.com/web/about/security/intelligence/ios-ref.html\n\n\nProducts Confirmed Not Vulnerable\n+--------------------------------\n\nCisco IOS-XR is not affected by this vulnerability. \n\nNo other Cisco products are currently known to be affected by this\nvulnerability. \n\nDetails\n=======\n\nSecure Shell (SSH) is a protocol which provides a secure remote\naccess connection to network devices. Repeated exploits\ncould create a sustained DoS condition. SSH can be\nconfigured as part of the AutoSecure feature in the initial\nconfiguration of IOS devices, AutoSecure run after initial\nconfiguration, or manually. SSH is enabled any time RSA keys are\ngenerated such as when an http secure-server or trust points for\ndigital certificates are configured. Devices that are not configured\nto accept SSHv2 connections are not affected by this vulnerability. \n\nA complete TCP three-way handshake is required to exploit this\nvulnerability. Reverse SSH traffic uses TCP port 22 by default. \n\nVulnerability Scoring Details\n=============================\n\nCisco has scored the vulnerability in this advisory based on the\nCommon Vulnerability Scoring System (CVSS). The CVSS scoring in this\nsecurity advisory is in accordance with CVSS version 2.0. \n\nCVSS is a standards-based scoring method that conveys vulnerability\nseverity and helps organizations determine the urgency and priority\nof a response. \n\nCisco has provided a base and temporal score. Customers can also\ncompute environmental scores that help determine the impact of the\nvulnerability in their own networks. \n\nCisco has provided additional information regarding CVSS at the\nfollowing link:\n\nhttp://www.cisco.com/web/about/security/intelligence/cvss-qandas.html\n\nCisco has also provided a CVSS calculator to compute the\nenvironmental impact for individual networks at the following link:\n\nhttp://intellishield.cisco.com/security/alertmanager/cvss\n\n\n* CSCtr49064 - Cisco IOS Software Reverse SSH Denial of Service\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\n\nImpact\n======\n\nSuccessful exploitation of this vulnerability could allow an\nunauthenticated, remote attacker to create a DoS condition by causing\nthe device to reload. Repeated exploits could create a sustained DoS\ncondition. \n\nSoftware Versions and Fixes\n===========================\n\nWhen considering software upgrades, customers are advised to consult\nthe Cisco Security Advisories and Responses archive at:\nhttp://www.cisco.com/go/psirt and review subsequent advisories to determine\nexposure and a complete upgrade solution. \n\nIn all cases, customers should ensure that the devices to be upgraded\ncontain sufficient memory and confirm that current hardware and\nsoftware configurations will continue to be supported properly by the\nnew release. If the information is not clear, customers are advised\nto contact the Cisco Technical Assistance Center (TAC) or their\ncontracted maintenance providers. If a particular train is vulnerable, the\nearliest releases that contain the fix are listed in the First Fixed\nRelease column. The First Fixed Release for All Advisories in the\nMarch 2012 Bundled Publication column lists the earliest possible\nreleases that correct all the published vulnerabilities in the Cisco\nIOS Software Security Advisory bundled publication. Cisco recommends\nupgrading to the latest available release, where possible. This tool is available on the Cisco Security Intelligence\nOperations (SIO) portal at:\nhttp://tools.cisco.com/security/center/selectIOSVersion.x\n\n+-------------------------------------------------------------------+\n| Major | Availability of Repaired Releases |\n| Release | |\n|----------+--------------------------------------------------------|\n| Affected | |First Fixed Release for All |\n|12.0-Based| First Fixed Release |Advisories in the March 2012|\n| Releases | |Cisco IOS Software Security |\n| | |Advisory Bundled Publication|\n|-------------------------------------------------------------------|\n| There are no affected 12.0 based releases |\n|-------------------------------------------------------------------|\n| Affected | |First Fixed Release for All |\n|12.2-Based| First Fixed Release |Advisories in the March 2012|\n| Releases | |Cisco IOS Software Security |\n| | |Advisory Bundled Publication|\n|----------+---------------------------+----------------------------|\n|12.2 |Not vulnerable |Vulnerable;

Customers should\nbe aware of the limitations and vulnerabilities of SSH version 1\nprotocol before applying this workaround. \n\nvty Access Class\n+---------------\n\nIt is possible to limit the exposure of the Cisco device by applying\na vty access class to allow only known, trusted hosts to connect to\nthe device via SSH. \n\nFor more information on restricting traffic to a vty, please consult:\nhttp://www.cisco.com/en/US/docs/ios/12_2/ipaddr/command/reference/1rfip1.html#wp1017389\n\nThe following example permits access to the vty lines from the\n192.168.1.0/24 netblock and the single IP address 172.16.1.2 while\ndenying access from anywhere else:\n\nRouter(config)# access-list 1 permit 192.168.1.0 0.0.0.255\nRouter(config)# access-list 1 permit host 172.16.1.2\nRouter(config)# line vty 0 4\nRouter(config-line)# access-class 1 in\n\nDifferent Cisco platforms support a different amount of terminal\nlines. Check your device\u0027s configuration to determine the correct\nnumber of terminal lines for your platform. \n\nInfrastructure Access Control Lists\n+----------------------------------\n\nAlthough it is often difficult to block traffic transiting your\nnetwork, it is possible to identify traffic that should never be\nallowed to target your infrastructure devices and block that traffic\nat the border of your network. Infrastructure access control lists\n(iACLs) are considered a network security best practice and should be\nconsidered as a long-term addition to good network security as well\nas a workaround for this specific vulnerability. The ACL example\nshown below should be included as part of the deployed infrastructure\naccess-list, which will protect all devices with IP addresses in the\ninfrastructure IP address range. \n\nA sample access list for devices running Cisco IOS is below:\n\n!--- Permit SSH services from trusted hosts destined \n\n!--- to infrastructure addresses. \n\naccess-list 150 permit tcp TRUSTED_HOSTS MASK\nINFRASTRUCTURE_ADDRESSES MASK eq 22\n\n!--- Deny SSH packets from all other sources destined to\ninfrastructure addresses. \n\naccess-list 150 deny tcp any INFRASTRUCTURE_ADDRESSES MASK eq 22\n\n!--- Permit all other traffic to transit the device. \n\naccess-list 150 permit IP any any\n\ninterface serial 2/0\n\n ip access-group 150 in\n\nThe white paper titled \"Protecting Your Core: Infrastructure\nProtection Access Control Lists\" presents guidelines and recommended\ndeployment techniques for infrastructure protection access lists. \nThis white paper is located at:\nhttp://www.cisco.com/en/US/tech/tk648/tk361/technologies_white_paper09186a00801a1a55.shtml\n\nControl Plane Policing\n+---------------------\n\nThe Control Plane Policing (CoPP) feature may be used to mitigate\nthese vulnerabilities. In the following example, only SSH traffic\nfrom trusted hosts with receive destination IP addresses is permitted\nto reach the route processor (RP). \n\nNote: Dropping traffic from unknown or untrusted IP addresses may\naffect hosts with dynamically assigned IP addresses from connecting\nto the Cisco IOS device. \n\n access-list 152 deny tcp TRUSTED_ADDRESSES MASK any eq 22\n\n access-list 152 permit tcp any any eq 22\n\n !\n\n class-map match-all COPP-KNOWN-UNDESIRABLE\n\n match access-group 152\n\n !\n\n !\n\n policy-map COPP-INPUT-POLICY\n\n class COPP-KNOWN-UNDESIRABLE\n\n drop\n\n !\n\n control-plane\n\n service-policy input COPP-INPUT-POLICY\n\nIn the above CoPP example, the ACL entries that match the exploit\npackets with the permit action result in these packets being\ndiscarded by the policy-map drop function, while packets that match\nthe deny action are not affected by the policy-map drop function. \n\nAdditional information on the configuration and use of the CoPP\nfeature can be found at the following URL: \nhttp://www.cisco.com/en/US/prod/collateral/iosswrel/ps6537/ps6586/ps6642/prod_white_paper0900aecd804fa16a.html\n\nObtaining Fixed Software\n========================\n\nCisco has released free software updates that address the\nvulnerability described in this advisory. Prior to deploying\nsoftware, customers are advised to consult their maintenance\nproviders or check the software for feature set compatibility and\nknown issues that are specific to their environments. \n\nCustomers may only install and expect support for feature sets they\nhave purchased. By installing, downloading, accessing, or otherwise\nusing such software upgrades, customers agree to follow the terms of\nthe Cisco software license at:\nhttp://www.cisco.com/en/US/docs/general/warranty/English/EU1KEN_.html\nor as set forth at http://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, upgrades should be\nobtained through the Software Center on Cisco.com at:\nhttp://www.cisco.com\n\nCustomers Using Third-Party Support Organizations\n+------------------------------------------------\n\nCustomers with Cisco products that 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 organization for assistance with the appropriate\ncourse of action. \n\nThe effectiveness of any workaround or fix depends on specific\ncustomer situations, such as product mix, network topology, traffic\nbehavior, and organizational mission. Because of the variety of\naffected products and releases, customers should consult their\nservice providers or support organizations to ensure that any applied\nworkaround or fix is the most appropriate in the intended network\nbefore it is deployed. \n\nCustomers Without Service Contracts\n+----------------------------------\n\nCustomers who purchase directly from Cisco but do not hold a Cisco\nservice contract and customers who make purchases through third-party\nvendors but are unsuccessful in obtaining fixed software through\ntheir point of sale should obtain upgrades by contacting the Cisco\nTechnical Assistance Center (TAC):\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 the product serial number available and be\nprepared to provide the URL of this advisory as evidence of\nentitlement to a free upgrade. Customers without service contracts\nshould request free upgrades through the TAC. \n\nRefer to Cisco Worldwide Contacts at:\nhttp://www.cisco.com/en/US/support/tsd_cisco_worldwide_contacts.html \nfor additional TAC contact information, including localized telephone \nnumbers, instructions, and e-mail addresses for support in various languages. \n\nExploitation and Public Announcements\n=====================================\n\nThe Cisco Product Security Incident Response Team (PSIRT) is not\naware of any public announcements or malicious use of the\nvulnerability that is described in this advisory. \n\nThis vulnerability was reported to Cisco by a customer. \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.
