This vulnerability exists because the web-based management interface does not sufficiently validate user-supplied input. An attacker could exploit this vulnerability by injecting malicious code into specific pages of 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. To exploit this vulnerability, the attacker would need valid administrative credentials.","severity":{"version":"3.1","score":4.8,"vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:C/C:L/I:L/A:N","level":"medium","assessor":"cna","from":"cve"},"epss":{"day":"2026-11-12","score":0.00594,"percentile":0.489,"model":"v2026.06.15"},"facts":{"in_kev":false,"known_exploited":false,"public_exploit":false,"fix_available":false},"cwes":["CWE-79"],"published":"2021-10-21T02:50:28Z","modified":"2026-06-17T03:56:34Z","products":[{"vendor":"cisco","product":"cisco secure workload"},{"vendor":"cisco","product":"tetration"}],"references":[{"url":"https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-sec-work-xss-t6SYtu8Q","tags":["vendor-advisory","x_refsource_CISCO","x_transferred","Vendor Advisory"]},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2021-34789"},{"url":"https://github.com/advisories/GHSA-6p9m-phxh-7h4x"}],"sources":{"cve":[{"id":"CVE-2021-34789","title":"Cisco Tetration Stored Cross-Site Scripting Vulnerability","description":"A vulnerability in the web-based management interface of Cisco Tetration could allow an authenticated, remote attacker to perform a stored cross-site scripting (XSS) attack on an affected system.
