This vulnerability is due to insufficient input validation of user-supplied data. An attacker could exploit this vulnerability by entering crafted text into various input fields within the web-based management interface. A successful exploit could allow the attacker to perform a stored XSS attack, which could allow the execution of scripts within the context of other users of the interface.","severity":{"version":"3.1","score":5.4,"vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N","level":"medium","assessor":"cna","from":"cve"},"epss":{"day":"2026-11-10","score":0.005,"percentile":0.43179,"model":"v2026.06.15"},"facts":{"in_kev":false,"known_exploited":false,"public_exploit":false,"fix_available":false},"cwes":["CWE-79"],"published":"2023-04-05T00:00:00Z","modified":"2026-06-17T05:29:28Z","products":[{"vendor":"cisco","product":"cisco unified contact center express"},{"vendor":"cisco","product":"unified_contact_center_express"}],"references":[{"url":"https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-uccx-xss-GO9L9xxr","tags":["vendor-advisory","x_transferred","Vendor Advisory"]},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2023-20096"},{"url":"https://github.com/advisories/GHSA-4v5g-36mr-fcgx"}],"sources":{"cve":[{"id":"CVE-2023-20096","title":"Cisco Unified Contact Center Express Stored Cross-Site Scripting Vulnerability","description":"A vulnerability in the web-based management interface of Cisco Unified Contact Center Express (Unified CCX) could allow an authenticated, remote attacker to perform a stored cross-site scripting (XSS) attack.
