The vulnerability is due to insufficient input validation by the web-based management interface. An attacker could exploit this vulnerability by inserting malicious data into a specific data field in the interface. A successful exploit could allow the attacker to execute arbitrary script code in the context of the affected interface or access sensitive, browser-based information.","severity":{"version":"3.0","score":5.9,"vector":"CVSS:3.0/AV:N/AC:L/PR:H/UI:R/S:C/C:L/I:L/A:L","level":"medium","assessor":"cna","from":"cve"},"epss":{"day":"2026-11-09","score":0.00622,"percentile":0.5014,"model":"v2026.06.15"},"facts":{"in_kev":false,"known_exploited":false,"public_exploit":false,"fix_available":false},"cwes":["CWE-79"],"published":"2020-08-26T16:16:33Z","modified":"2026-06-17T03:18:16Z","products":[{"vendor":"cisco","product":"cisco data center network manager"},{"vendor":"cisco","product":"data_center_network_manager"}],"references":[{"url":"https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-dcnm-xss-stored-w4rJZJtO","tags":["vendor-advisory","x_refsource_CISCO","x_transferred","Vendor Advisory"]},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2020-3439"},{"url":"https://github.com/advisories/GHSA-hpf2-qwj9-g86h"}],"sources":{"cve":[{"id":"CVE-2020-3439","title":"Cisco Data Center Network Manager Stored Cross-Site Scripting Vulnerability","description":"A vulnerability in the web-based management interface of Cisco Data Center Network Manager (DCNM) Software could allow an authenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the interface.
