The vulnerability exists because the web-based management interface does not properly validate user-supplied input. An attacker could exploit this vulnerability by intercepting a request from a user and injecting malicious data into an HTTP header. 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":4.7,"vector":"CVSS:3.0/AV:N/AC:H/PR:N/UI:R/S:C/C:L/I:L/A:N","level":"medium","assessor":"cna","from":"cve"},"epss":{"day":"2026-11-09","score":0.00716,"percentile":0.54039,"model":"v2026.06.15"},"facts":{"in_kev":false,"known_exploited":false,"public_exploit":false,"fix_available":false},"cwes":["CWE-79"],"published":"2020-07-31T00:00:16Z","modified":"2026-06-17T03:18:20Z","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-3jkDLsLV","tags":["vendor-advisory","x_refsource_CISCO","x_transferred","Vendor Advisory"]},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2020-3460"},{"url":"https://github.com/advisories/GHSA-943v-975q-f779"}],"sources":{"cve":[{"id":"CVE-2020-3460","title":"Cisco Data Center Network Manager Cross-Site Scripting Vulnerability","description":"A vulnerability in the web-based management interface of Cisco Data Center Network Manager (DCNM) could allow an unauthenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the interface.
