{"id":"CVE-2020-3510","state":"PUBLISHED","title":"Cisco IOS XE Software for Catalyst 9200 Series Switches Umbrella Connector Denial of Service Vulnerability","description":"A vulnerability in the Umbrella Connector component of Cisco IOS XE Software for Cisco Catalyst 9200 Series Switches could allow an unauthenticated, remote attacker to trigger a reload, resulting in a denial of service condition on an affected device. The vulnerability is due to insufficient error handling when parsing DNS requests. An attacker could exploit this vulnerability by sending a series of malicious DNS requests to an Umbrella Connector client interface of an affected device. A successful exploit could allow the attacker to cause a crash of the iosd process, which triggers a reload of the affected device.","publishedAt":"2020-09-24T17:51:44.121Z","updatedAt":"2024-11-13T18:00:31.250Z","severity":{"score":8.6,"label":"High","version":"3.0","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:N/A:H","source":"cisco"},"assigner":"cisco","products":["Cisco Cisco IOS XE Software"],"affected":[{"vendor":"Cisco","product":"Cisco IOS XE Software","versions":[{"version":"n/a","status":"affected"}]}],"references":["https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-iosxe-umbrella-dos-t2QMUX37"],"weaknesses":["CWE-388"],"ingestedAt":"2026-10-29T19:47:29.373Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2020/3xxx/CVE-2020-3510.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.1","cveMetadata":{"cveId":"CVE-2020-3510","state":"PUBLISHED","datePublished":"2020-09-24T17:51:44.121Z","dateUpdated":"2024-11-13T18:00:31.250Z","assignerShortName":"cisco","assignerOrgId":"d1c1063e-7a18-46af-9102-31f8928bc633","dateReserved":"2019-12-12T00:00:00.000Z"},"containers":{"cna":{"title":"Cisco IOS XE Software for Catalyst 9200 Series Switches Umbrella Connector Denial of Service Vulnerability","descriptions":[{"lang":"en","value":"A vulnerability in the Umbrella Connector component of Cisco IOS XE Software for Cisco Catalyst 9200 Series Switches could allow an unauthenticated, remote attacker to trigger a reload, resulting in a denial of service condition on an affected device.
