This vulnerability is due to insufficient input validation by the web-based management interface. An attacker could exploit this vulnerability by inserting malicious data in a specific data field in the interface. 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":"3.0","score":4.8,"vector":"CVSS:3.0/AV:N/AC:L/PR:H/UI:R/S:C/C:L/I:L/A:N","level":"medium","assessor":"cna","from":"cve"},"epss":{"day":"2026-11-10","score":0.00592,"percentile":0.48649,"model":"v2026.06.15"},"facts":{"in_kev":false,"known_exploited":false,"public_exploit":false,"fix_available":false},"cwes":["CWE-79"],"published":"2021-10-21T02:50:22Z","modified":"2026-06-17T03:56:30Z","products":[{"vendor":"cisco","product":"cisco telepresence management suite (tms)"},{"vendor":"cisco","product":"telepresence_management_suite"}],"references":[{"url":"https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-tms-xss-CwjZJSQc","tags":["vendor-advisory","x_refsource_CISCO","x_transferred","Vendor Advisory"]},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2021-34760"},{"url":"https://github.com/advisories/GHSA-q7jm-4rr7-gcqq"}],"sources":{"cve":[{"id":"CVE-2021-34760","title":"Cisco TelePresence Management Suite Stored Cross-Site Scripting Vulnerability","description":"A vulnerability in the web-based management interface of Cisco TelePresence Management Suite (TMS) Software could allow an authenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the interface.
