An attacker could exploit this vulnerability by submitting malicious content to an affected device and using the device to generate a document that contains sensitive information. A successful exploit could allow the attacker to alter the standard layout of the device-generated documents, access arbitrary files from the underlying operating system, and conduct server-side request forgery (SSRF) attacks. To successfully exploit this vulnerability, an attacker would need valid credentials for a user account with policy-editing permissions, such as Network Admin, Intrusion Admin, or any custom user role with the same capabilities.","severity":{"version":"3.1","score":5.5,"vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:L/I:L/A:N","level":"medium","assessor":"cna","from":"cve"},"epss":{"day":"2026-11-11","score":0.00429,"percentile":0.37533,"model":"v2026.06.15"},"facts":{"in_kev":false,"known_exploited":false,"public_exploit":false,"fix_available":false},"cwes":["CWE-20","CWE-79"],"published":"2024-10-23T17:07:36Z","modified":"2026-06-17T07:06:14Z","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-html-inj-nfJeYHxz","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-2024-20274"},{"url":"https://github.com/advisories/GHSA-4jwf-2c3g-hqmj"}],"sources":{"cve":[{"id":"CVE-2024-20274","title":"Cisco Secure Firewall Management Center HTML Injection Vulnerability","description":"A vulnerability in the web-based management interface of Cisco Secure Firewall Management Center (FMC) Software, formerly Firepower Management Center Software, could allow an authenticated, remote attacker to inject arbitrary HTML content into a device-generated document.\r\n\r\nThis vulnerability is due to improper validation of user-supplied data.
