The vulnerability exists because the web-based management interface does not properly validate user-supplied input. An attacker could exploit this vulnerability by inserting malicious data into a specific data field in an affected interface. A successful exploit could allow the attacker to execute arbitrary script code in the context of the affected interface.","severity":{"version":"3.0","score":6.4,"vector":"CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N","level":"medium","assessor":"cna","from":"cve"},"epss":{"day":"2026-11-10","score":0.00626,"percentile":0.50355,"model":"v2026.06.15"},"facts":{"in_kev":false,"known_exploited":false,"public_exploit":false,"fix_available":false},"cwes":["CWE-79"],"published":"2020-10-08T04:20:25Z","modified":"2026-06-17T03:18:32Z","products":[{"vendor":"cisco","product":"cisco sd-wan vmanage"},{"vendor":"cisco","product":"sd-wan"}],"references":[{"url":"https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-sdwan-xss-xXeLFpC3","tags":["vendor-advisory","x_refsource_CISCO","x_transferred","Third Party Advisory"]},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2020-3536"},{"url":"https://github.com/advisories/GHSA-gcjx-pff6-p887"}],"sources":{"cve":[{"id":"CVE-2020-3536","title":"Cisco SD-WAN vManage Cross-Site Scripting Vulnerability","description":"A vulnerability in the web-based management interface of Cisco SD-WAN vManage Software could allow an authenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the interface.
