Vulnerability from variot
Memory leak in the Data-link switching (aka DLSw) feature in Cisco IOS 12.1 through 12.4 and 15.0 through 15.1, and IOS XE 3.1.xS before 3.1.3S and 3.2.xS before 3.2.1S, when implemented over Fast Sequence Transport (FST), allows remote attackers to cause a denial of service (memory consumption and device reload or hang) via a crafted IP protocol 91 packet, aka Bug ID CSCth69364. Cisco IOS is prone to a remote denial-of-service vulnerability. An attacker can exploit this issue to cause an affected device to reload, denying service to legitimate users. This issue is being tracked by Cisco Bug ID CSCth69364. Cisco's Internet Operating System (IOS) is a complex operating system optimized for Internet interconnection. Remote illegal attackers can use this vulnerability to cause denial of service.
Cisco has released free software updates that address this vulnerability.
This advisory is posted at http://www.cisco.com/warp/public/707/cisco-sa-20110928-dlsw.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
Vulnerable Products +------------------
Cisco IOS devices with the DLSw promiscuous feature enabled are affected by the vulnerability described in this advisory. Devices with the DLSw promiscuous feature enabled contain a line in the configuration defining a local DLSw peer with the promiscuous keyword. This configuration can be observed by issuing the command "show running-config". Systems configured with the DLSw promiscuous feature enabled contain a line similar to one of the following:
dlsw local-peer promiscuous
or
dlsw local-peer peer-id <IP address> promiscuous
To determine the software that runs on a Cisco IOS device, log in to the device and issue the "show version" command to display the system banner. Cisco IOS Software identifies itself as "Cisco Internetwork Operating System Software" or "Cisco IOS Software." Other Cisco devices do not have the "show version" command or give different output.
The following example shows output from a device running IOS version 15.0(1)M1:
Router> show version
Cisco IOS Software, C3900 Software (C3900-UNIVERSALK9-M), Version 15.0(1)M1, RELEASE SOFTWARE (fc1)

Products Confirmed Not Vulnerable +--------------------------------
No other Cisco products are currently known to be affected by this vulnerability.
Details
DLSw provides a means of transporting IBM Systems Network Architecture (SNA) and network BIOS (NetBIOS) traffic over an IP network. The Cisco implementation of DLSw over Fast Sequence Transport (FST) uses IP Protocol 91. The promiscuous DLSw feature permits the local peer to establish connection with remote peers that are not statically configured.
A Cisco IOS device that is configured for DLSw listens for IP protocol 91 packets. Depending on the DLSw configuration, UDP port 2067, and, one or more TCP ports can also be opened. The vulnerability described in this document can only be exploited via IP Protocol 91 and can not be exploited using either the UDP or TCP transports.
Devices with only statically configured DLSw peers are not affected by this vulnerability.
Vulnerability Scoring Details
Cisco has provided scores for the vulnerability in this advisory based on the Common Vulnerability Scoring System (CVSS). The CVSS scoring in this Security Advisory is done in accordance with CVSS version 2.0.
CVSS is a standards-based scoring method that conveys vulnerability severity and helps determine urgency and priority of response.
Cisco has provided a base and temporal score. Customers can then compute environmental scores to assist in determining the impact of the vulnerability in individual networks.
Cisco has provided an FAQ to answer additional questions regarding CVSS at:
http://www.cisco.com/web/about/security/intelligence/cvss-qandas.html
Cisco has also provided a CVSS calculator to help compute the environmental impact for individual networks at:
http://intellishield.cisco.com/security/alertmanager/cvss
- CSCth69364 ("DLSw FST Memory Leak")
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 the vulnerability may result in a memory leak that can lead to a denial of service condition.
To identify the memory leak caused by this vulnerability, issue the "show dlsw peers | include FST.*DISCONN" command; a monotonically increasing list of FST peers that remain in the DISCONN state indicates that memory is being held, as shown in the following example:
Router> show dlsw peers | include FST.*DISCONN
FST 176.74.146.194 DISCONN 1 0 prom 0 - - -
FST 9.180.128.186 DISCONN 1 0 prom 0 - - -
FST 139.71.105.39 DISCONN 1 0 prom 0 - - -
FST 138.150.39.18 DISCONN 1 0 prom 0 - - -
FST 253.240.220.167 DISCONN 1 0 prom 0 - - -
FST 252.186.119.224 DISCONN 1 0 prom 0 - - -
FST 41.255.172.252 DISCONN 1 0 prom 0 - - -

Cisco IOS XR Software +--------------------
Cisco IOS XR Software is not affected by any of the vulnerabilities in the September 2011 bundled publication.
Workarounds
This vulnerability can be mitigated by using Control Plane Policing (CoPP) to only allow IP Protocol 91 packets sent by valid peers.
Mitigation techniques that can be deployed on Cisco devices within the network are available in the Cisco Applied Mitigation Bulletin companion document for this advisory:
http://www.cisco.com/warp/public/707/cisco-amb-20110928-dlsw.shtml
Control Plane Policing +---------------------
Control Plane Policing (CoPP) can be used to block untrusted IP Protocol 91 packets sent to the affected device. CoPP may be configured on a device to protect the management and control planes to minimize the risk and effectiveness of direct infrastructure attacks by explicitly permitting, and if configured, rate-limiting only authorized traffic that is sent to infrastructure devices in accordance with existing security policies and configurations. The following example, which uses 192.168.100.1 to represent a trusted host, can be adapted to your network.
!-- Deny FST traffic on IP protocol 91 from trusted
!-- hosts to all IP addresses configured on all interfaces of the affected device
!-- so that it will be allowed by the CoPP feature
access-list 111 deny 91 host 192.168.100.1 any
!-- Permit all other FST traffic on IP protocol 91
!-- sent to all IP addresses configured on all interfaces of the affected
!-- device so that it will be policed and dropped by the CoPP feature
access-list 111 permit 91 any any
!-- Permit (Police or Drop)/Deny (Allow) all other Layer3
!-- and Layer4 traffic in accordance with existing security
!-- policies and configurations for traffic that is authorized
!-- to be sent to infrastructure devices
!-- Create a Class-Map for traffic to be policed by
!-- the CoPP feature
class-map match-all drop-fst-91-class
match access-group 111
!-- Create a Policy-Map that will be applied to the
!-- Control-Plane of the device.
policy-map input-CoPP-policy
class drop-fst-91-class
drop
!-- Apply the Policy-Map to the Control-Plane of the
!-- device
control-plane
service-policy input input-CoPP-policy
In the above CoPP example, the access control list entries (ACEs) that match the potential 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 (not shown) are not affected by the policy-map drop function. Note that in the 12.2S and 12.0S Cisco IOS trains the policy-map syntax is different, as shown in the following example:
policy-map input-CoPP-policy
class drop-fst-91-class
police 32000 1500 1500 conform-action drop exceed-action drop
Additional information on the CoPP feature is available at: Control Plane Policing Implementation Best Practices.

"data": "Memory leak in the Data-link switching (aka DLSw) feature in Cisco IOS 12.1 through 12.4 and 15.0 through 15.1, and IOS XE 3.1.xS before 3.1.3S and 3.2.xS before 3.2.1S, when implemented over Fast Sequence Transport (FST), allows remote attackers to cause a denial of service (memory consumption and device reload or hang) via a crafted IP protocol 91 packet, aka Bug ID CSCth69364. Cisco IOS is prone to a remote denial-of-service vulnerability. \nAn attacker can exploit this issue to cause an affected device to reload, denying service to legitimate users. \nThis issue is being tracked by Cisco Bug ID CSCth69364. Cisco\u0027s Internet Operating System (IOS) is a complex operating system optimized for Internet interconnection. Remote illegal attackers can use this vulnerability to cause denial of service. \n\nCisco has released free software updates that address this\nvulnerability. \n\nThis advisory is posted at\nhttp://www.cisco.com/warp/public/707/cisco-sa-20110928-dlsw.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\nVulnerable Products\n+------------------\n\nCisco IOS devices with the DLSw promiscuous feature enabled are affected\nby the vulnerability described in this advisory. Devices with the DLSw\npromiscuous feature enabled contain a line in the configuration defining\na local DLSw peer with the promiscuous keyword. This configuration\ncan be observed by issuing the command \"show running-config\". Systems\nconfigured with the DLSw promiscuous feature enabled contain a line\nsimilar to one of the following:\n\n dlsw local-peer promiscuous\n\nor\n\n dlsw local-peer peer-id \u003cIP address\u003e promiscuous\n\nTo determine the software that runs on a Cisco IOS device, log in to\nthe device and issue the \"show version\" command to display the system\nbanner. Cisco IOS Software identifies itself as \"Cisco Internetwork\nOperating System Software\" or \"Cisco IOS Software.\" Other Cisco devices\ndo not have the \"show version\" command or give different output. \n\nThe following example shows output from a device running IOS version\n15.0(1)M1:\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\nAdditional information about Cisco IOS Software release naming\nconventions is available in the white paper Cisco IOS and NX-OS\nSoftware Reference Guide at:\n\nhttp://www.cisco.com/web/about/security/intelligence/ios-ref.html. \n\nProducts Confirmed Not Vulnerable\n+--------------------------------\n\nNo other Cisco products are currently known to be affected by this\nvulnerability. \n\nDetails\n=======\n\nDLSw provides a means of transporting IBM Systems Network\nArchitecture (SNA) and network BIOS (NetBIOS) traffic over an IP\nnetwork. The Cisco implementation of DLSw over Fast Sequence\nTransport (FST) uses IP Protocol 91. The promiscuous DLSw feature\npermits the local peer to establish connection with remote peers that\nare not statically configured. \n\nA Cisco IOS device that is configured for DLSw listens for IP\nprotocol 91 packets. Depending on the DLSw configuration, UDP port\n2067, and, one or more TCP ports can also be opened. The\nvulnerability described in this document can only be exploited via IP\nProtocol 91 and can not be exploited using either the UDP or TCP\ntransports. \n\nDevices with only statically configured DLSw peers are not affected\nby 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* CSCth69364 (\"DLSw FST Memory Leak\")\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 the vulnerability may result in a memory\nleak that can lead to a denial of service condition. \n\nTo identify the memory leak caused by this vulnerability, issue the\n\"show dlsw peers | include FST.*DISCONN\" command; a monotonically\nincreasing list of FST peers that remain in the DISCONN state indicates\nthat memory is being held, as shown in the following example:\n\n Router\u003e show dlsw peers | include FST.*DISCONN\n FST 176.74.146.194 DISCONN 1 0 prom 0 - - -\n FST 9.180.128.186 DISCONN 1 0 prom 0 - - -\n FST 139.71.105.39 DISCONN 1 0 prom 0 - - -\n FST 138.150.39.18 DISCONN 1 0 prom 0 - - -\n FST 253.240.220.167 DISCONN 1 0 prom 0 - - -\n FST 252.186.119.224 DISCONN 1 0 prom 0 - - -\n FST 41.255.172.252 DISCONN 1 0 prom 0 - - -\n ! --- Output truncated\n Router\u003e\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 |\n| 12.0-Based | First Fixed Release | for All Advisories in |\n| Releases | | the September 2011 |\n| | | Bundled Publication |\n|------------------------------------------------------------|\n| There are no affected 12.0-based releases |\n|------------------------------------------------------------|\n| Affected | | First Fixed Release |\n| 12.1-Based | First Fixed Release | for All Advisories in |\n| Releases | | the September 2011 |\n| | | Bundled Publication |\n|------------+-----------------------+-----------------------|\n| | Vulnerable;

CoPP may be configured on a device to protect the\nmanagement and control planes to minimize the risk and effectiveness\nof direct infrastructure attacks by explicitly permitting, and if\nconfigured, rate-limiting only authorized traffic that is sent to\ninfrastructure devices in accordance with existing security policies\nand configurations. The following example, which uses 192.168.100.1\nto represent a trusted host, can be adapted to your network. \n\n !-- Deny FST traffic on IP protocol 91 from trusted\n !-- hosts to all IP addresses configured on all interfaces of the affected device\n !-- so that it will be allowed by the CoPP feature\n\n access-list 111 deny 91 host 192.168.100.1 any\n\n !-- Permit all other FST traffic on IP protocol 91\n !-- sent to all IP addresses configured on all interfaces of the affected\n !-- device so that it will be policed and dropped by the CoPP feature\n\n access-list 111 permit 91 any any\n\n !-- Permit (Police or Drop)/Deny (Allow) all other Layer3\n !-- and Layer4 traffic in accordance with existing security\n !-- policies and configurations for traffic that is authorized\n !-- to be sent to infrastructure devices\n\n !-- Create a Class-Map for traffic to be policed by\n !-- the CoPP feature\n\n class-map match-all drop-fst-91-class\n match access-group 111\n\n !-- Create a Policy-Map that will be applied to the\n !-- Control-Plane of the device. \n\n policy-map input-CoPP-policy\n class drop-fst-91-class\n drop\n\n\n !-- Apply the Policy-Map to the Control-Plane of the\n !-- device\n\n control-plane\n service-policy input input-CoPP-policy\n\n\nIn the above CoPP example, the access control list entries (ACEs)\nthat match the potential exploit packets with the \"permit\" action\nresult in these packets being discarded by the policy map \"drop\"\nfunction, while packets that match the deny action (not shown) are\nnot affected by the policy-map drop function. Note that in the 12.2S\nand 12.0S Cisco IOS trains the policy-map syntax is different, as\nshown in the following example:\n\n policy-map input-CoPP-policy\n class drop-fst-91-class\n police 32000 1500 1500 conform-action drop exceed-action drop\n\nAdditional information on the CoPP feature is available at: Control\nPlane Policing Implementation Best Practices. \n\nObtaining Fixed Software\n========================\n\nCisco has released free software updates that address these\nvulnerabilities. Prior to deploying software, customers should\nconsult their maintenance provider or check the software for feature\nset compatibility 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 during Cisco internal testing. \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.
