This vulnerability is due to insufficient validation of user-supplied input by the web-based management interface. An attacker could exploit this vulnerability by inserting crafted input into various data fields in an affected interface. 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":4.8,"vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:C/C:L/I:L/A:N","level":"medium","assessor":"cna","from":"cve"},"epss":{"day":"2026-11-11","score":0.00407,"percentile":0.35481,"model":"v2026.06.15"},"facts":{"in_kev":false,"known_exploited":false,"public_exploit":false,"fix_available":false},"cwes":["CWE-79"],"published":"2024-10-23T17:08:24Z","modified":"2026-06-17T07:06:19Z","products":[{"vendor":"cisco","product":"cisco firepower management center"},{"vendor":"cisco","product":"secure_firewall_management_center"}],"references":[{"url":"https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-fmc-xss-dhJxQYZs","tags":["Vendor Advisory"]},{"url":"https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-fmc-xss-M446vbEO","tags":["Broken Link"]},{"url":"https://sec.cloudapps.cisco.com/security/center/viewErp.x?alertId=ERP-75300","tags":["Vendor Advisory"]},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2024-20300"},{"url":"https://github.com/advisories/GHSA-p6rg-m225-p79c"}],"sources":{"cve":[{"id":"CVE-2024-20300","title":"Cisco Firepower Management Center Software Cross-Site Scripting Vulnerability","description":"A vulnerability in the web-based management interface of Cisco Firepower Management Center (FMC) Software could allow an authenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the interface of an affected device.
