This vulnerability exists because the web-based management interface does not properly validate user-supplied input. An attacker could exploit this vulnerability by persuading a user of the interface to click a crafted link. A successful exploit could allow the attacker to execute arbitrary script code in the context of the 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":"2026-11-10","score":0.00833,"percentile":0.57939,"model":"v2026.06.15"},"facts":{"in_kev":false,"known_exploited":false,"public_exploit":false,"fix_available":false},"cwes":["CWE-79"],"published":"2020-10-21T18:37:07Z","modified":"2026-06-17T03:18:41Z","products":[{"vendor":"cisco","product":"adaptive_security_appliance"},{"vendor":"cisco","product":"adaptive_security_appliance_software"},{"vendor":"cisco","product":"cisco adaptive security appliance (asa) software"}],"references":[{"url":"https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-asa-rxss-L54Htxp","tags":["vendor-advisory","x_refsource_CISCO","x_transferred","Vendor Advisory"]},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2020-3599"},{"url":"https://github.com/advisories/GHSA-fxhx-wgc5-xg5f"}],"sources":{"cve":[{"id":"CVE-2020-3599","title":"Cisco Adaptive Security Appliance Software Web-Based Management Interface Reflected Cross-Site Scripting Vulnerability","description":"A vulnerability in the web-based management interface of Cisco Adaptive Security Appliance (ASA) Software could allow an unauthenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the interface.
