Vulnerability from csaf_cisco
Notes
{ "document": { "acknowledgments": [ { "summary": "This vulnerability was found during internal security testing." } ], "category": "csaf_security_advisory", "csaf_version": "2.0", "notes": [ { "category": "summary", "text": "A vulnerability in the Network Address Translation (NAT) Session Initiation Protocol (SIP) Application Layer Gateway (ALG) of Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause an affected device to reload.\r\n\r\nThe vulnerability is due to improper processing of transient SIP packets on which NAT is performed on an affected device. An attacker could exploit this vulnerability by using UDP port 5060 to send crafted SIP packets through an affected device that is performing NAT for SIP packets. A successful exploit could allow an attacker to cause the device to reload, resulting in a denial of service (DoS) condition.\r\n\r\nCisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.\r\n\r\nThis advisory is available at the following link:\r\nhttps://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190925-sip-alg [\"https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190925-sip-alg\"]\r\n\r\nThis advisory is part of the September 25, 2019, release of the Cisco IOS and IOS XE Software Security Advisory Bundled Publication, which includes 12 Cisco Security Advisories that describe 13 vulnerabilities. For a complete list of the advisories and links to them, see Cisco Event Response: September 2019 Semiannual Cisco IOS and IOS XE Software Security Advisory Bundled Publication [\"https://sec.cloudapps.cisco.com/security/center/viewErp.x?alertId=ERP-72547\"].", "title": "Summary" }, { "category": "general", "text": "This vulnerability affects the following Cisco devices if they are running a vulnerable release of Cisco IOS XE Software that is configured for NAT operation:\r\n\r\nCisco 1100, 4200, and 4300 Integrated Services Routers (ISRs)\r\nCisco Cloud Services Router (CSR) 1000V Series\r\nCisco Enterprise Network Compute System (ENCS)\r\nCisco Integrated Services Virtual Router (ISRv)\r\n\r\nNote: The SIP ALG feature is enabled as soon as NAT is configured on the device.\r\n\r\nFor information about which Cisco IOS XE Software releases are vulnerable, see the Fixed Software [\"#fixed\"] section of this advisory.\r\n Assessing the NAT Configuration\r\nTo determine whether NAT has been enabled in the Cisco IOS XE Software configuration, the ip nat inside or ip nat outside commands must be on different interfaces and at least one ip nat global configuration command must be in the configuration. Alternatively, in the case of the NAT Virtual Interface, the ip nat enable interface command will be present.\r\n\r\nThe show running-config | include ip nat command can be used to determine whether NAT is in the configuration, as illustrated in the following example of a vulnerable configuration:\r\n\r\n\r\nRouter#show running-config | include ip nat\r\n ip nat inside\r\n ip nat outside\r\n ip nat inside source static 192.0.2.100 10.0.0.1\r\n\r\nTo determine whether the SIP ALG is disabled in the NAT configuration, use the show running-config | include ip nat privileged EXEC command. The presence of no ip nat service sip in the output of show running-config | include ip nat indicates that the SIP ALG is disabled in the NAT configuration.\r\n\r\nThe following is the output of show running-config | include ip nat in Cisco IOS XE Software that has the SIP ALG disabled in the NAT configuration:\r\n\r\n\r\nRouter#show running-config | include ip nat\r\nip nat inside\r\nip nat outside\r\nip nat inside source static 192.0.2.100 10.0.0.1 vrf sip\r\nno ip nat service sip udp port 5060\r\n\r\nIf no ip nat service sip does not appear in the output of show running-config | include ip nat, and the device runs an affected version of Cisco IOS XE Software with NAT enabled, that configuration is vulnerable.", "title": "Vulnerable Products" }, { "category": "general", "text": "Only products listed in the Vulnerable Products [\"#vp\"] section of this advisory are known to be affected by this vulnerability.\r\n\r\nCisco has confirmed that this vulnerability does not affect Cisco IOS Software, Cisco IOS XR Software, or Cisco NX-OS Software.", "title": "Products Confirmed Not Vulnerable" }, { "category": "general", "text": "A successful exploit of this vulnerability will cause an affected device to reload and generate a crashinfo file.\r\n\r\nA successful exploit of this vulnerability may be confirmed by decoding the stack trace for the device and determining whether the stack trace correlates with this vulnerability.\r\n\r\nContact the Cisco Technical Assistance Center (TAC) to review the crashinfo file and determine whether the device has been compromised by exploitation of this vulnerability.", "title": "Indicators of Compromise" }, { "category": "general", "text": "There are no workarounds that address this vulnerability.\r\n\r\nTo mitigate this vulnerability, administrators can disable the SIP ALG by configuring the following on the affected device until an upgrade is possible:\r\n\r\n\r\n no ip nat service sip udp port 5060", "title": "Workarounds" }, { "category": "general", "text": "Cisco has released free software updates that address the vulnerability described in this advisory. 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 and Alerts 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:\r\nhttps://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 a tool, the Cisco IOS Software Checker [\"https://sec.cloudapps.cisco.com/security/center/softwarechecker.x\"], that identifies 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 this tool to perform the following tasks:\r\n\r\nInitiate a search by choosing one or more releases from a drop-down list or uploading a file from a local system for the tool to parse\r\nEnter the output of the show version command for the tool to parse\r\nCreate a custom search by including all previously published Cisco Security Advisories, a specific advisory, or all advisories in the most recent bundled publication\r\n\r\nTo determine whether a release is affected by any published Cisco Security Advisory, use the Cisco IOS Software Checker [\"https://sec.cloudapps.cisco.com/security/center/softwarechecker.x\"] on Cisco.com or enter a Cisco IOS or IOS XE Software release\u2014for example, 15.1(4)M2 or 3.13.8S\u2014in the following field:\r\n\r\n\r\n\r\nBy default, the Cisco IOS Software Checker includes results only for vulnerabilities that have a Critical or High Security Impact Rating (SIR). To include results for Medium SIR vulnerabilities, use the Cisco IOS Software Checker on Cisco.com and check the Medium check box in the Impact Rating drop-down list.\r\n\r\nFor a mapping of Cisco IOS XE Software releases to Cisco IOS Software releases, refer to the Cisco IOS XE 2 Release Notes [\"https://www.cisco.com/c/en/us/td/docs/ios/ios_xe/2/release/notes/rnasr21/rnasr21_gen.html#wp3000032\"], Cisco IOS XE 3S Release Notes [\"https://www.cisco.com/c/en/us/td/docs/ios/ios_xe/3/release/notes/asr1k_rn_3s_rel_notes/asr1k_rn_3s_sys_req.html#wp3069754\"], or Cisco IOS XE 3SG Release Notes [\"https://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst4500/release/note/OL_24726.html#pgfId-2570252\"], depending on the Cisco IOS XE Software release.", "title": "Fixed Software" }, { "category": "general", "text": "To learn about Cisco security vulnerability disclosure policies and publications, see the Security Vulnerability Policy [\"https://sec.cloudapps.cisco.com/security/center/resources/security_vulnerability_policy.html\"].
