{"id":"CVE-2021-1575","aliases":["EUVD-2021-7042","GHSA-44jq-q5pq-hm7w"],"status":"published","title":"Cisco Virtualized Voice Browser Cross-Site Scripting Vulnerability","description":"A vulnerability in the web-based management interface of Cisco Virtualized Voice Browser could allow an unauthenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the interface. 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 an affected interface to click a crafted link. A successful exploit could allow the attacker to execute arbitrary script code in the context of the affected 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":"2026-11-09","score":0.00813,"percentile":0.57251,"model":"v2026.06.15"},"facts":{"in_kev":false,"known_exploited":false,"public_exploit":false,"fix_available":false},"cwes":["CWE-79"],"published":"2021-07-08T18:30:18Z","modified":"2026-06-17T03:32:05Z","products":[{"vendor":"cisco","product":"cisco virtualized voice browser"},{"vendor":"cisco","product":"virtualized_voice_browser"}],"references":[{"url":"https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-vvb-xss-wG4zXRp3","tags":["vendor-advisory","x_refsource_CISCO","x_transferred","Vendor Advisory"]},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2021-1575"},{"url":"https://github.com/advisories/GHSA-44jq-q5pq-hm7w"}],"sources":{"cve":[{"id":"CVE-2021-1575","title":"Cisco Virtualized Voice Browser Cross-Site Scripting Vulnerability","description":"A vulnerability in the web-based management interface of Cisco Virtualized Voice Browser could allow an unauthenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the interface.
