This vulnerability is due to insufficient input validation of a parameter that is used by the web-based management interface. 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 code in the context of the interface, access sensitive, browser-based information, or cause an affected device to reboot under certain conditions.","severity":{"version":"3.1","score":5.4,"vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:N/A:L","level":"medium","assessor":"cna","from":"cve"},"epss":{"day":"2026-11-10","score":0.00773,"percentile":0.56032,"model":"v2026.06.15"},"facts":{"in_kev":false,"known_exploited":false,"public_exploit":false,"fix_available":false},"cwes":["CWE-79"],"published":"2021-07-22T15:20:48Z","modified":"2026-06-17T03:32:08Z","products":[{"vendor":"cisco","product":"cisco unified customer voice portal (cvp)"},{"vendor":"cisco","product":"unified_customer_voice_portal"}],"references":[{"url":"https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-cvp-xss-yvE6L8Zq","tags":["vendor-advisory","x_refsource_CISCO","x_transferred","Patch","Vendor Advisory"]},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2021-1599"},{"url":"https://github.com/advisories/GHSA-76jc-v27q-5hhx"}],"sources":{"cve":[{"id":"CVE-2021-1599","title":"Cisco Unified Customer Voice Portal Cross-Site Scripting Vulnerability","description":"A vulnerability in the web-based management interface of Cisco Unified Customer Voice Portal (CVP) could allow an authenticated, remote attacker to perform a cross-site scripting (XSS) attack against a user.
