Una explotaci\u00f3n exitosa podr\u00eda permitir que el atacante cree o sobrescriba archivos arbitrarios en el dispositivo afectado, lo que podr\u00eda generar una condici\u00f3n de denegaci\u00f3n de servicio (DoS). Cisco ha publicado actualizaciones de software que solucionan esta vulnerabilidad. No existen workarounds que solucionen esta vulnerabilidad.\"}],\"metrics\":{\"cvssMetricV31\":[{\"source\":\"psirt@cisco.com\",\"type\":\"Primary\",\"cvssData\":{\"version\":\"3.1\",\"vectorString\":\"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:N/I:H/A:H\",\"baseScore\":8.4,\"baseSeverity\":\"HIGH\",\"attackVector\":\"LOCAL\",\"attackComplexity\":\"LOW\",\"privilegesRequired\":\"LOW\",\"userInteraction\":\"NONE\",\"scope\":\"CHANGED\",\"confidentialityImpact\":\"NONE\",\"integrityImpact\":\"HIGH\",\"availabilityImpact\":\"HIGH\"},\"exploitabilityScore\":2.0,\"impactScore\":5.8}]},\"weaknesses\":[{\"source\":\"psirt@cisco.com\",\"type\":\"Primary\",\"description\":[{\"lang\":\"en\",\"value\":\"CWE-22\"}]}],\"configurations\":[{\"nodes\":[{\"operator\":\"OR\",\"negate\":false,\"cpeMatch\":[{\"vulnerable\":true,\"criteria\":\"cpe:2.3:a:cisco:catalyst_sd-wan_manager:17.2.4:*:*:*:*:*:*:*\",\"matchCriteriaId\":\"A0D5F32C-BFC1-49CC-BE96-920FCBE567B0\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:a:cisco:catalyst_sd-wan_manager:17.2.5:*:*:*:*:*:*:*\",\"matchCriteriaId\":\"F621202C-3851-4D7E-BFA2-DABB08E73DB6\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:a:cisco:catalyst_sd-wan_manager:17.2.6:*:*:*:*:*:*:*\",\"matchCriteriaId\":\"38132BE5-528B-472E-9249-B226C0DE1C80\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:a:cisco:catalyst_sd-wan_manager:17.2.7:*:*:*:*:*:*:*\",\"matchCriteriaId\":\"37C817B2-DDB9-4CAF-96C9-776482A8597D\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:a:cisco:catalyst_sd-wan_manager:17.2.8:*:*:*:*:*:*:*\",\"matchCriteriaId\":\"AC5D29FD-0917-4C1F-AE75-2D63F5C9C58D\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:a:cisco:catalyst_sd-wan_manager:17.2.9:*:*:*:*:*:*:*\",\"matchCriteriaId\":\"1E3090C4-15E6-4746-B0D2-27665AB91B08\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:a:cisco:catalyst_sd-wan_manager:17.2.10:*:*:*:*:*:*:*\",\"matchCriteriaId\":\"04E924CC-3161-436D-93F0-066F76172F55\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:a:cisco:catalyst_sd-wan_manager:18.2.0:*:*:*:*:*:*:*\",\"matchCriteriaId\":\"7ED059CD-AD0A-4748-8390-8CDCF4C4D1CC\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:a:cisco:catalyst_sd-wan_manager:18.3.0:*:*:*:*:*:*:*\",\"matchCriteriaId\":\"6990E97D-30E9-42A9-AE6A-CC597DF75B0B\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:a:cisco:catalyst_sd-wan_manager:18.3.1:*:*:*:*:*:*:*\",\"matchCriteriaId\":\"15B60BA4-EA02-4D0D-82C3-1B08016EF5AE\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:a:cisco:catalyst_sd-wan_manager:18.3.1.1:*:*:*:*:*:*:*\",\"matchCriteriaId\":\"E9DC51F7-72D4-4593-8DDE-8AA3955BB826\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:a:cisco:catalyst_sd-wan_manager:18.3.3:*:*:*:*:*:*:*\",\"matchCriteriaId\":\"B047A011-1C27-4D86-99C1-BFCDC7F04A9B\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:a:cisco:catalyst_sd-wan_manager:18.3.3.1:*:*:*:*:*:*:*\",\"matchCriteriaId\":\"DADEA8FB-3298-4534-B65E-81060E3DB45A\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:a:cisco:catalyst_sd-wan_manager:18.3.4:*:*:*:*:*:*:*\",\"matchCriteriaId\":\"F4C6DF1F-4995-4486-8F90-9EFD6417ABA6\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:a:cisco:catalyst_sd-wan_manager:18.3.5:*:*:*:*:*:*:*\",\"matchCriteriaId\":\"6D249954-93E0-4124-B9BA-84B9F34D7CB1\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:a:cisco:catalyst_sd-wan_manager:18.3.6:*:*:*:*:*:*:*\",\"matchCriteriaId\":\"5B24396C-3732-4CF8-B01A-62C77D20E7FC\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:a:cisco:catalyst_sd-wan_manager:18.3.6.1:*:*:*:*:*:*:*\",\"matchCriteriaId\":\"B7F20EBE-DFDF-4996-93D1-28EE776BC777\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:a:cisco:catalyst_sd-wan_manager:18.3.7:*:*:*:*:*:*:*\",\"matchCriteriaId\":\"3DF09CAB-CA1B-428E-9A0B-AADACE9201A0\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:a:cisco:catalyst_sd-wan_manager:18.3.8:*:*:*:*:*:*:*\",\"matchCriteriaId\":\"D99ED480-C206-48DD-9DF3-FC60D91B98A3\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:a:cisco:catalyst_sd-wan_manager:18.4.0:*:*:*:*:*:*:*\",\"matchCriteriaId\":\"4DC515B6-27A3-4723-9792-2BA42EF63E44\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:a:cisco:catalyst_sd-wan_manager:18.4.0.1:*:*:*:*:*:*:*\",\"matchCriteriaId\":\"DEC0BBDA-FAE5-4AF7-81C8-83041A58E8E7\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:a:cisco:catalyst_sd-wan_manager:18.4.1:*:*:*:*:*:*:*\",\"matchCriteriaId\":\"7A066E28-31B0-46C7-ABB8-F5D1F3A303C9\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:a:cisco:catalyst_sd-wan_manager:18.4.3:*:*:*:*:*:*:*\",\"matchCriteriaId\":\"C8F536CC-29D6-401E-92C5-964FDBDCCE65\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:a:cisco:catalyst_sd-wan_manager:18.4.4:*:*:*:*:*:*:*\",\"matchCriteriaId\":\"9139593A-9414-488D-AA3A-5560C643587D\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:a:cisco:catalyst_sd-wan_manager:18.4.5:*:*:*:*:*:*:*\",\"matchCriteriaId\":\"07BFB47E-F456-4782-98D7-68D02500FDD3\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:a:cisco:catalyst_sd-wan_manager:18.4.302:*:*:*:*:*:*:*\",\"matchCriteriaId\":\"33BEBE47-AF47-4994-871D-5969270EE5AD\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:a:cisco:cata

The vulnerability is due to insufficient input validation for specific commands. An attacker could exploit this vulnerability by including crafted arguments to those specific commands. A successful exploit could allow the attacker to create or overwrite arbitrary files on the affected device, which could result in a DoS condition. Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.

Vulnerable Products

This vulnerability affects the following Cisco products if they are running a vulnerable release of Cisco SD-WAN Software: SD-WAN vBond Orchestrator Software SD-WAN vEdge Cloud Routers SD-WAN vEdge Routers SD-WAN vManage Software SD-WAN vSmart Controller Software For information about which Cisco software releases are vulnerable, see the Fixed Software ["#fs"] section of this advisory.

Products Confirmed Not Vulnerable

Only products listed in the Vulnerable Products ["#vp"] section of this advisory are known to be affected by this vulnerability. Cisco has confirmed that this vulnerability does not affect Cisco IOS XE SD-WAN Software.

Workarounds

There are no workarounds that address this vulnerability.

Fixed Software

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: https://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"] Additionally, 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. When 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. In 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. Customers Without Service Contracts Customers 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"] Customers 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. Fixed Releases Customers are advised to upgrade to an appropriate fixed software release as indicated in the following table(s). To ensure a complete upgrade solution, consider that this advisory is part of a collection that includes the following advisories: cisco-sa-vepegr-4xynYLUj ["https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-vepegr-4xynYLUj"]: Cisco SD-WAN Software Privilege Escalation Vulnerability cisco-sa-vepescm-BjgQm4vJ ["https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-vepescm-BjgQm4vJ"]: Cisco SD-WAN Software Privilege Escalation Vulnerability cisco-sa-vepeshlg-tJghOQcA ["https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-vepeshlg-tJghOQcA"]: Cisco SD-WAN Software Privilege Escalation Vulnerability cisco-sa-vepestd-8C3J9Vc ["https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-vepestd-8C3J9Vc"]: Cisco SD-WAN Software Privilege Escalation Vulnerability cisco-sa-vman-traversal-hQh24tmk ["https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-vman-traversal-hQh24tmk"]: Cisco SD-WAN vManage Software Directory Traversal Vulnerability cisco-sa-vmanage-escalation-Jhqs5Skf ["https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-vmanage-escalation-Jhqs5Skf"]: Cisco SD-WAN vManage Software Privilege Escalation Vulnerability cisco-sa-vsoln-arbfile-gtsEYxns ["https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-vsoln-arbfile-gtsEYxns"]: Cisco SD-WAN Software Arbitrary File Creation Vulnerability Cisco SD-WAN Software Release First Fixed Release for this Vulnerability First Fixed Release for All Vulnerabilities Described in the Collection of Advisories Earlier than 18.3 Migrate to a fixed release.
