        "text": "A vulnerability in the Common Open Policy Service (COPS) of Cisco IOS XE Software for Cisco cBR-8 Converged Broadband Routers could allow an unauthenticated, remote attacker to cause resource exhaustion, resulting in a denial of service (DoS) condition.\r\n\r\nThis vulnerability is due to a deadlock condition in the code when processing COPS packets under certain conditions. An attacker could exploit this vulnerability by sending COPS packets with high burst rates to an affected device. A successful exploit could allow the attacker to cause the CPU to consume excessive resources, which prevents other control plane processes from obtaining resources and results in a DoS.\r\n\r\nCisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.\r\n\r\n\r\n\r\nThis advisory is part of the September 2021 release of the Cisco IOS and IOS XE Software Security Advisory Bundled Publication.

If the output returns either packetcable or packetcable multimedia, as shown in the following example, then COPS is listening on the device:\r\n\r\n\r\ncBR-8# show running-config | include packetcable\r\npacketcable\r\npacketcable multimedia\r\ncBR-8#",

        "text": "There are no workarounds that address this vulnerability. However, there are mitigations:\r\n\r\nCustomers who use packetcable or packetcable multimedia and leverage a COPS server in their environment can configure Cisco cBR-8 Routers to process packets from trusted COPS servers only, as shown in the following example:\r\n\r\n\r\ncBR-8# configure terminal\r\ncBR-8(config)#access-list 55 remark ** Permit only Trusted COPS servers **\r\ncBR-8(config)#access-list 55 permit \u003cCOPSERVER1\u003e\r\ncBR-8(config)#access-list 55 permit \u003cCOPSERVER2\u003e\ncBR-8(config)#access-list 55 deny any\r\ncBR-8(config)#cops listener access-list 55\r\ncBR-8#\r\n\r\nCustomers who are using packetcable or packetcable multimedia but do not leverage a COPS server in their environment can configure Cisco cBR-8 Routers to deny processing any COPS packets, as shown in following example:\r\n\r\n\r\ncBR-8# configure terminal\r\ncBR-8(config)#access-list 55 remark ** Drop All COPS packets **\r\ncBR-8(config)#access-list 55 deny any\r\ncBR-8(config)#cops listener access-list 55\r\ncBR-8#\r\n\n\r\nAnother way to minimize the impact of this vulnerability is to lower the COPS server keep alive setting to a value lower than the routing protocol keep alive timers. Having a COPS keep alive setting of 15 seconds will not remove the vulnerability, but it would force the COPS connection to be automatically renewed and clear the deadlock condition on the Cisco cBR8 Router code before it impacts other control plane protocols. The keep alive setting is controlled by the COPS server.\r\n\r\nWhile these mitigations have been deployed and were proven successful in a test environment, customers should determine the applicability and effectiveness in their own environment and under their own use conditions. Customers should be aware that any workaround or mitigation that is implemented may negatively impact the functionality or performance of their network based on intrinsic customer deployment scenarios and limitations. Customers should not deploy any workarounds or mitigations before first evaluating the applicability to their own environment and any impact to such environment.",

Customers may only install and expect support for software versions and feature sets for which they have purchased a license. By installing, downloading, accessing, or otherwise using such software upgrades, customers agree to follow the terms of the Cisco software license:\r\nhttps://www.cisco.com/c/en/us/products/end-user-license-agreement.html [\"https://www.cisco.com/c/en/us/products/end-user-license-agreement.html\"]\r\n\r\nAdditionally, customers may only download software for which they have a valid license, procured from Cisco directly, or through a Cisco authorized reseller or partner. In most cases this will be a maintenance upgrade to software that was previously purchased. Free security software updates do not entitle customers to a new software license, additional software feature sets, or major revision upgrades.\r\n\r\nWhen considering software upgrades [\"https://sec.cloudapps.cisco.com/security/center/resources/security_vulnerability_policy.html#fixes\"], customers are advised to regularly consult the advisories for Cisco products, which are available from the Cisco Security Advisories page [\"https://www.cisco.com/go/psirt\"], to determine exposure and a complete upgrade solution.\r\n\r\nIn 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.\r\n Customers Without Service Contracts\r\nCustomers 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 TAC: https://www.cisco.com/c/en/us/support/web/tsd-cisco-worldwide-contacts.html [\"https://www.cisco.com/c/en/us/support/web/tsd-cisco-worldwide-contacts.html\"]\r\n\r\nCustomers should have the product serial number available and be prepared to provide the URL of this advisory as evidence of entitlement to a free upgrade.\r\n    Cisco IOS and IOS XE Software\r\nTo help customers determine their exposure to vulnerabilities in Cisco IOS and IOS XE Software, Cisco provides the Cisco Software Checker [\"https://sec.cloudapps.cisco.com/security/center/softwarechecker.x\"] to identify any Cisco Security Advisories that impact a specific software release and the earliest release that fixes the vulnerabilities described in each advisory (\u201cFirst Fixed\u201d). If applicable, the tool also returns the earliest release that fixes all the vulnerabilities described in all the advisories identified (\u201cCombined First Fixed\u201d).\r\n\r\nCustomers can use the Cisco Software Checker [\"https://sec.cloudapps.cisco.com/security/center/softwarechecker.x\"] to search advisories in the following ways:\r\n\r\nChoose the software and one or more releases\r\nUpload a .txt file that includes a list of specific releases\r\nEnter the output of the show version command\r\n\r\nAfter initiating a search, customers can customize the search to include all Cisco Security Advisories, a specific advisory, or all advisories in the most recent bundled publication.\r\n\r\nCustomers can also use the following form to determine whether a release is affected by any Cisco Security Advisory by entering a Cisco IOS or IOS XE Software release\u2014for example, 15.1(4)M2 or 3.13.8S:",
