This vulnerability is due to insufficient validation of user-supplied input that is processed by the web-based management interface. An attacker could exploit this vulnerability by adding malicious code to the configuration by using the web-based management interface. A successful exploit could allow the attacker to execute arbitrary code in the context of the interface or access sensitive, browser-based information.","severity":{"version":"3.1","score":5.5,"vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:L/I:L/A:N","level":"medium","assessor":"cna","from":"cve"},"epss":{"day":"2026-11-10","score":0.00723,"percentile":0.54334,"model":"v2026.06.15"},"facts":{"in_kev":false,"known_exploited":false,"public_exploit":false,"fix_available":false},"cwes":["CWE-79","CWE-87"],"published":"2021-11-18T23:50:29Z","modified":"2026-06-17T04:06:34Z","products":[{"vendor":"cisco","product":"cisco common services platform collector software"},{"vendor":"cisco","product":"common_services_platform_collector"}],"references":[{"url":"https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-CSPC-XSS-KjrNbM3p","tags":["vendor-advisory","x_refsource_CISCO","x_transferred","Vendor Advisory"]},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2021-40131"},{"url":"https://github.com/advisories/GHSA-gmxx-4882-2mxv"}],"sources":{"cve":[{"id":"CVE-2021-40131","title":"Cisco Common Services Platform Collector Stored Cross-Site Scripting Vulnerability","description":"A vulnerability in the web-based management interface of Cisco Common Services Platform Collector (CSPC) could allow an authenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the interface.
