The vulnerability is due to insufficient validation of user-supplied input by the web-based management interface of the affected service. An attacker could exploit this vulnerability by persuading a user to click a malicious link. 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":"3.1","score":6.1,"vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","level":"medium","assessor":"cna","from":"cve"},"epss":{"day":"2026-11-09","score":0.0083,"percentile":0.57801,"model":"v2026.06.15"},"facts":{"in_kev":false,"known_exploited":false,"public_exploit":false,"fix_available":false},"cwes":["CWE-79"],"published":"2020-08-17T18:00:40Z","modified":"2026-06-17T03:18:20Z","products":[{"vendor":"cisco","product":"cisco webex meetings"},{"vendor":"cisco","product":"webex_meetings_online"}],"references":[{"url":"https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-webex-mttngs-xss-3VbdxDuF","tags":["vendor-advisory","x_refsource_CISCO","x_transferred","Vendor Advisory"]},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2020-3463"},{"url":"https://github.com/advisories/GHSA-xfjw-w4w6-9cxc"}],"sources":{"cve":[{"id":"CVE-2020-3463","title":"Cisco Webex Meetings Reflected Cross-Site Scripting Vulnerability","description":"A vulnerability in the web-based management interface of Cisco Webex Meetings could allow an unauthenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the web-based management interface of the affected service.
