Vulnerability from variot
Unspecified vulnerability in the Multi Protocol Label Switching (MPLS) Forwarding Infrastructure (MFI) in Cisco IOS 12.2 and 12.4 allows remote attackers to cause a denial of service (memory corruption) via crafted packets for which the software path is used. A successful exploit may cause an affected device to reload, denying service to legitimate users. ----------------------------------------------------------------------

TITLE: Cisco IOS Multiple Vulnerabilities
SECUNIA ADVISORY ID: SA31990
VERIFY ADVISORY: http://secunia.com/advisories/31990/
CRITICAL: Moderately critical
IMPACT: Exposure of sensitive information, DoS, System access
WHERE:
From remote
OPERATING SYSTEM: Cisco IOS R12.x http://secunia.com/advisories/product/50/ Cisco IOS 12.x http://secunia.com/advisories/product/182/
DESCRIPTION: Some vulnerabilities have been reported in Cisco IOS, which can be exploited by malicious people to disclose sensitive information, cause a DoS (Denial of Service), or to compromise a vulnerable system.
1) An unspecified error exists in the processing of SSL packets during the termination of an SSL session, which can potentially be exploited to crash an affected system.
2) Two unspecified errors exist within the processing of Protocol Independent Multicast (PIM) packets, which can be exploited to cause an affected device to reload.
3) Unspecified errors within the processing of segmented Skinny Call Control Protocol (SCCP) messages can be exploited to cause a Cisco IOS device to reload.
Successful exploitation requires that the device is configured with Network Address Translation (NAT) SCCP Fragmentation Support.
4) A memory leak in the processing of Session Initiation Protocol (SIP) messages can be exploited to cause a DoS for all voice services.
6) An unspecified error in the IOS Intrusion Prevention System (IPS) feature when processing certain IPS signatures that use the SERVICE.DNS engine can be exploited to cause a DoS via specially crafted network traffic.
7) A security issue exists in the processing of extended communities with Multi Protocol Label Switching (MPLS) Virtual Private Networks (VPN), which can lead to traffic leaking from one MPLS VPN to another.
NOTE: This security issue was introduced with CSCee83237.
9) An unspecified error within the Application Inspection Control (AIC) can be exploited to cause a reload of an affected device via specially crafted HTTP packets.
10) An unspecified error in the processing of Layer 2 Tunneling Protocol (L2TP) packets can be exploited to cause an affected device to reload via a specially crafted L2TP packets.
Successful exploitation requires that the L2TP mgmt daemon process is running. This process may be enabled e.g. via Layer 2 virtual private networks (L2VPN), Layer 2 Tunnel Protocol Version 3 (L2TPv3), Stack Group Bidding Protocol (SGBP), or Cisco Virtual Private Dial-Up Networks (VPDN).
11) An unspecified error exists in the processing of IPC messages. This can be exploited to reload an affected device via a specially crafted UDP packet sent to port 1975.
12) A security issue is caused due to the device automatically enabling SNMP with a default community string, which can be exploited to gain control an affected system.
Successful exploitation requires that a device is configured for linecard redundancy.
SOLUTION: Update to the fixed version (please see the vendor's advisories for details).
PROVIDED AND/OR DISCOVERED BY: Reported by the vendor.

Affected Products
Devices that run Cisco IOS software (including those that support Cisco IOS Software Modularity) and support MFI are affected if they are configured for MPLS.
Vulnerable Products +------------------
A device that runs Cisco IOS software and supports MFI will have mfi_ios in the output of the show subsys command. The following example shows output from a device that supports MFI:
Router#show subsys name mfi_ios
Class Version
mfi_ios Protocol 1.000.001
Router#
The following example shows output from a device that is configured for MPLS:
Router#show mpls interface
Interface IP Tunnel BGP Static Operational
Ethernet0/0 Yes (ldp) No No No Yes
Router#
To determine the software running on a Cisco product, log in to the device and issue the "show version" command to display the system banner. Cisco IOS software will identify itself as "Internetwork Operating System Software" or simply "IOS". On the next line of output, the image name will be displayed between parentheses, followed by "Version" and the IOS release name. Other Cisco devices will not have the "show version" command or will give different output.
The following example identifies a Cisco product that is running Cisco IOS release 12.4(11)T2:
Router#show version
Cisco IOS Software,7200 Software (C7200-ADVSECURITYK9-M), Version 12.4(11)T2, RELEASE SOFTWARE (fc4)

Additional information on the Cisco IOS release naming conventions can be found on the document entitled "White Paper: Cisco IOS Reference Guide", which is available at http://www.cisco.com/warp/public/620/1.html
Products Confirmed Not Vulnerable +--------------------------------
Devices running Cisco IOS software versions that do not include MFI are not vulnerable.
Devices that are not configured for MPLS are not vulnerable.
Devices that are running Cisco IOS XR software are not vulnerable.
No other Cisco products are currently known to be affected by these vulnerabilities.
Details
In newer versions of Cisco IOS software, a new packet forwarding infrastructure was introduced to improve scalability and performance. This forwarding infrastructure, called MFI, is transparent to the user. MFI manages MPLS data structures used for forwarding and replaces the older implementation, Label Forwarding Information Base (LFIB). Such packets can be sent from the local segment to the interfaces that are configured for MPLS or via tunnel interfaces that are configured for MPLS. To target a remote system in an MPLS network, an attacker needs to have access to the MPLS network through an MPLS-enabled interface. MPLS packets are dropped on interfaces that are not configured for MPLS.
Devices that support MFI will have mfi_ios in the output of the show subsys command. Interfaces that are enabled for MPLS can be seen by the show mpls interface command.
More information on MFI can be found at the following link:
http://www.cisco.com/en/US/docs/ios/mpls/configuration/guide/mp_lsc_removed.html
This vulnerability is documented in the Cisco Bug ID CSCsk93241 and has been assigned Common Vulnerabilities and Exposures (CVE) ID CVE-2008-3804.

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.
Each row of the Cisco IOS software table (below) names a Cisco IOS release train. If a given release train is vulnerable, then the earliest possible releases that contain the fix (along with the anticipated date of availability for each, if applicable) are listed in the "First Fixed Release" column of the table. The "Recommended Release" column indicates the releases which have fixes for all the published vulnerabilities at the time of this Advisory. A device running a release in the given train that is earlier than the release in a specific column (less than the First Fixed Release) is known to be vulnerable. Cisco recommends upgrading to a release equal to or later than the release in the "Recommended Releases" column of the table.

Workarounds
MPLS is normally enabled on physical and logical interfaces that are shared with other MPLS-enabled devices. It can be disabled on interfaces where MPLS is not necessary and from which a potential attack can be launched. This action may help to limit the exposure of this vulnerability.
If it is not possible to disable MPLS on interfaces from which an attack can be launched, there are no workarounds to mitigate this vulnerability.
Obtaining Fixed Software
Cisco has released free software updates that address these vulnerabilities. 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/products/prod_warranties_item09186a008088e31f.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.

The following\nexample shows output from a device that supports MFI:\n\n Router#show subsys name mfi_ios\n Class Version\n mfi_ios Protocol 1.000.001\n Router#\n\nThe following example shows output from a device that is configured\nfor MPLS:\n\n Router#show mpls interface\n Interface IP Tunnel BGP Static Operational\n Ethernet0/0 Yes (ldp) No No No Yes\n Router#\n\nTo determine the software running on a Cisco product, log in to the\ndevice and issue the \"show version\" command to display the system\nbanner. Cisco IOS software will identify itself as \"Internetwork\nOperating System Software\" or simply \"IOS\". On the next line of\noutput, the image name will be displayed between parentheses,\nfollowed by \"Version\" and the IOS release name. Other Cisco devices\nwill not have the \"show version\" command or will give different\noutput. \n\nThe following example identifies a Cisco product that is running\nCisco IOS release 12.4(11)T2:\n\n Router#show version\n Cisco IOS Software,7200 Software (C7200-ADVSECURITYK9-M), Version 12.4(11)T2, RELEASE SOFTWARE (fc4)\n Technical Support: http://www.cisco.com/techsupport\n Copyright (c) 1986-2007 by Cisco Systems, Inc. \n Compiled Tue 01-May-07 04:19 by prod_rel_team\n\n \u003coutput truncated\u003e\n\nAdditional information on the Cisco IOS release naming conventions\ncan be found on the document entitled \"White Paper: Cisco IOS\nReference Guide\", which is available at \nhttp://www.cisco.com/warp/public/620/1.html\n\nProducts Confirmed Not Vulnerable\n+--------------------------------\n\nDevices running Cisco IOS software versions that do not include MFI\nare not vulnerable. \n\nDevices that are not configured for MPLS are not vulnerable. \n\nDevices that are running Cisco IOS XR software are not vulnerable. \n\nNo other Cisco products are currently known to be affected by these\nvulnerabilities. \n\nDetails \n=======\n\nIn newer versions of Cisco IOS software, a new packet forwarding\ninfrastructure was introduced to improve scalability and performance. \nThis forwarding infrastructure, called MFI, is transparent to the\nuser. MFI manages MPLS data structures used for forwarding and\nreplaces the older implementation, Label Forwarding Information Base\n(LFIB). Such\npackets can be sent from the local segment to the interfaces that are\nconfigured for MPLS or via tunnel interfaces that are configured for\nMPLS. To target a remote system in an MPLS network, an attacker needs\nto have access to the MPLS network through an MPLS-enabled interface. \nMPLS packets are dropped on interfaces that are not configured for\nMPLS. \n\nDevices that support MFI will have mfi_ios in the output of the show\nsubsys command. Interfaces that are enabled for MPLS can be seen by\nthe show mpls interface command. \n\nMore information on MFI can be found at the following link:\n\nhttp://www.cisco.com/en/US/docs/ios/mpls/configuration/guide/mp_lsc_removed.html\n\nThis vulnerability is documented in the Cisco Bug ID CSCsk93241 \nand has been assigned Common Vulnerabilities and Exposures (CVE) \nID CVE-2008-3804. \n\nVulnerability Scoring Details\n=============================\n\nCisco has provided scores for the vulnerabilities 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\nCSCsk93241 - Chunk memory corruption on LFDp Input Proc\n\nCVSS Base Score - 7.8\n\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\n Exploitability - Functional\n Remediation Level - Official-Fix\n Report Confidence - Confirmed\n\nImpact\n======\n\nSuccessful exploitation of this vulnerability may result in the\nreload of the device, leading to a DoS 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\ndetermine exposure 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\nEach row of the Cisco IOS software table (below) names a Cisco IOS\nrelease train. If a given release train is vulnerable, then the\nearliest possible releases that contain the fix (along with the\nanticipated date of availability for each, if applicable) are listed\nin the \"First Fixed Release\" column of the table. The \"Recommended\nRelease\" column indicates the releases which have fixes for all the\npublished vulnerabilities at the time of this Advisory. A device\nrunning a release in the given train that is earlier than the release\nin a specific column (less than the First Fixed Release) is known to\nbe vulnerable. Cisco recommends upgrading to a release equal to or\nlater than the release in the \"Recommended Releases\" column of the\ntable.

MPLS-enabled devices. It can be disabled on\ninterfaces where MPLS is not necessary and from which a potential\nattack can be launched. This action may help to limit the exposure of\nthis vulnerability. \n\nIf it is not possible to disable MPLS on interfaces from which an\nattack can be launched, there are no workarounds to mitigate this\nvulnerability. \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 sets\nthey have purchased. By installing, downloading, accessing or\notherwise using such software upgrades, customers agree to be bound\nby the terms of Cisco\u0027s software license terms found at \nhttp://www.cisco.com/en/US/products/prod_warranties_item09186a008088e31f.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 http://www.cisco.com/warp/public/687/Directory/DirTAC.shtml\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 found internally. \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.
