Vulnerability from variot
Cisco ONS 15310-CL, 15310-MA, 15327, 15454, 15454 SDH, and 15600 with software 7.0.2 through 7.0.6, 7.2.2, 8.0.x, 8.5.1, and 8.5.2 allows remote attackers to cause a denial of service (control-card reset) via a crafted TCP session. Cisco ONS is prone to a denial-of-service vulnerability when handling specially crafted TCP traffic. An attacker can exploit this issue to cause the control cards in the affected devices to reload, denying service to legitimate users. The following devices are affected: Cisco ONS 15310-CL and 15310-MA Cisco ONS 15327 Cisco ONS 15454 and 15454 SDH Cisco ONS 15600 This issue is being tracked by Cisco BugID CSCsr41128. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1
Cisco Security Advisory: Cisco ONS Platform Crafted Packet Vulnerability
Advisory ID: cisco-sa-20090114-ons
http://www.cisco.com/warp/public/707/cisco-sa-20090114-ons.shtml
Revision 1.0
For Public Release 2009 January 14 1600 UTC (GMT)
Summary
The Cisco ONS 15300 series Edge Optical Transport Platform, the Cisco ONS 15454 Optical Transport Platform, the Cisco ONS 15454 SDH Multiservice Platform, and the Cisco ONS 15600 Multiservice Switching Platform contains a vulnerability when processing TCP traffic streams that may result in a reload of the device control card.
Cisco has released free software updates that address this vulnerability.
There are no workarounds that mitigate this vulnerability. Several mitigations exist that can limit the exposure of this vulnerability. To determine your software version, view the Help > About window on the CTC management software). These control cards are usually connected to a Data Communications Network (DCN). In this context the term DCN is used to denote the network that transports management information between a management station and the network entity (NE). This definition of DCN is sometimes referred to as Management Communication Network (MCN). The DCN is usually physically or logically separated from the optical data network and isolated from the Internet. This limits the exposure to the exploitation of this vulnerability from the Internet.
A crafted stream of TCP traffic to the control cards on a node will result in a reset of the corresponding control cards on this node. A complete 3-way handshake is required on any open TCP port to be able to exploit this vulnerability.
The timing for the data channels traversing the switch is provided by the control cards.
When an active and a standby Cisco ONS 15310-MA, ONS 15310-CL, ONS 15327, ONS 15454 or ONS 15454 SDH control card reloads at the same time, the synchronous data channels traversing the switch drop traffic until the card comes back online. Asynchronous data channels traversing the switch are not impacted. Manageability functions provided by the network element using the CTX, CTX2500, XTC or TCC/ TCC+/TCC2/TCC2P control cards are not available until the control card comes back online.
On the Cisco ONS 15600 hardware, whenever both the active and standby control cards are rebooting at the same time, there is no impact to the data channels traversing the switch because the TSC performs a software reset which does not impact the timing being provided by the TSC for the data channels.
Manageability functions provided by the network element through the TSC control cards are not available until the control card comes back online.
This vulnerability is documented in Cisco bug ID CSCsr41128 and has been assigned Common Vulnerabilities and Exposures (CVE) identifier CVE-2008-3818.
Vulnerability Scoring Details
Cisco has provided scores for the vulnerabilities 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
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 will result in a reset of the node's control card. Repeated attempts to exploit this vulnerability could result in a sustained DoS condition, dropping the synchronous data channels traversing the switch (Cisco ONS 15310-MA, ONS 15310-CL, ONS 15327, ONS 15454, ONS 15454 SDH) and preventing manageability functions provided by the network element control cards (all ONS switches) until the control card comes back online.
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.

Workarounds
There are no workarounds for this vulnerability. The following general mitigation actions help prevent remote exploitation:
- Isolate DCN: Ensuring the DCN is physically or logically separated from the customer network and isolated from the Internet will limit the exposure to the exploitation of these vulnerabilities from the Internet or customer networks.
- Apply Transit Access Control Lists: Apply access control lists (ACLs) on routers / switches / firewalls installed in front of the vulnerable network devices such that TCP/IP traffic destined for the CTX, CTX2500, XTC, TCC2 /TCC2+/TCC2P, or TSC control cards on the ONS is allowed only from the network management workstations. For examples on how to apply ACLs on Cisco routers, refer to the white paper "Transit Access Control Lists: Filtering at Your Edge", which is available at the following link: http://www.cisco.com/en/US/customer/tech/tk648/tk361/technologies_white_paper09186a00801afc76.shtml

Cisco ONS is prone to a denial-of-service vulnerability when handling specially crafted TCP traffic. \nAn attacker can exploit this issue to cause the control cards in the affected devices to reload, denying service to legitimate users. \nThe following devices are affected:\nCisco ONS 15310-CL and 15310-MA\nCisco ONS 15327\nCisco ONS 15454 and 15454 SDH\nCisco ONS 15600\nThis issue is being tracked by Cisco BugID CSCsr41128. -----BEGIN PGP SIGNED MESSAGE-----\nHash: SHA1\n\nCisco Security Advisory: Cisco ONS Platform Crafted Packet\nVulnerability\n\nAdvisory ID: cisco-sa-20090114-ons\n\nhttp://www.cisco.com/warp/public/707/cisco-sa-20090114-ons.shtml\n\nRevision 1.0\n\nFor Public Release 2009 January 14 1600 UTC (GMT)\n\n- ---------------------------------------------------------------------\n\nSummary\n=======\n\nThe Cisco ONS 15300 series Edge Optical Transport Platform, the Cisco\nONS 15454 Optical Transport Platform, the Cisco ONS 15454 SDH\nMultiservice Platform, and the Cisco ONS 15600 Multiservice Switching\nPlatform contains a vulnerability when processing TCP traffic streams\nthat may result in a reload of the device control card. \n\nCisco has released free software updates that address this\nvulnerability. \n\nThere are no workarounds that mitigate this vulnerability. Several\nmitigations exist that can limit the exposure of this vulnerability. To determine your software\nversion, view the Help \u003e About window on the CTC management\nsoftware). These control cards are usually connected to a\nData Communications Network (DCN). In this context the term DCN is\nused to denote the network that transports management information\nbetween a management station and the network entity (NE). This\ndefinition of DCN is sometimes referred to as Management\nCommunication Network (MCN). The DCN is usually physically or\nlogically separated from the optical data network and isolated from\nthe Internet. This limits the exposure to the exploitation of this\nvulnerability from the Internet. \n\nA crafted stream of TCP traffic to the control cards on a node will\nresult in a reset of the corresponding control cards on this node. A\ncomplete 3-way handshake is required on any open TCP port to be able\nto exploit this vulnerability. \n\nThe timing for the data channels traversing the switch is provided by\nthe control cards. \n\nWhen an active and a standby Cisco ONS 15310-MA, ONS 15310-CL, ONS\n15327, ONS 15454 or ONS 15454 SDH control card reloads at the same\ntime, the synchronous data channels traversing the switch drop\ntraffic until the card comes back online. Asynchronous data channels\ntraversing the switch are not impacted. Manageability functions\nprovided by the network element using the CTX, CTX2500, XTC or TCC/\nTCC+/TCC2/TCC2P control cards are not available until the control\ncard comes back online. \n\nOn the Cisco ONS 15600 hardware, whenever both the active and standby\ncontrol cards are rebooting at the same time, there is no impact to\nthe data channels traversing the switch because the TSC performs a\nsoftware reset which does not impact the timing being provided by the\nTSC for the data channels. \n\nManageability functions provided by the network element through the\nTSC control cards are not available until the control card comes back\nonline. \n\nThis vulnerability is documented in Cisco bug ID CSCsr41128 \nand has been assigned Common Vulnerabilities and Exposures (CVE) \nidentifier CVE-2008-3818. \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\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 will result in a reset\nof the node\u0027s control card. Repeated attempts to exploit this\nvulnerability could result in a sustained DoS condition, dropping the\nsynchronous data channels traversing the switch (Cisco ONS 15310-MA,\nONS 15310-CL, ONS 15327, ONS 15454, ONS 15454 SDH) and preventing\nmanageability functions provided by the network element control cards\n(all ONS switches) until the control card comes back online. \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\n+-------------------------------------------------------------------------+\n| Affected Major Release | First Fixed Release |\n|---------------------------------+---------------------------------------|\n| 7.0 | Note: Releases prior to 7.0.2 are not |\n| | vulnerable.
