This vulnerability is due to an incorrect implementation of role-based access control (RBAC). An attacker could exploit this vulnerability by crafting a specific HTTP request with administrative credentials. A successful exploit could allow the attacker to generate a certificate that is signed and trusted by the ISE CA with arbitrary attributes. The attacker could use this certificate to access other networks or assets that are protected by certificate authentication.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:N/I:H/A:N","score":6.8},"cwes":["CWE-285"],"references":["http://www.securityfocus.com/bid/108356","https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190515-ise-certcreation","http://www.securityfocus.com/bid/108356","https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190515-ise-certcreation"],"products":["cisco:identity_services_engine"],"source":"nvd","synced_at":"2026-10-19T20:56:19.218283075+00:00"},"epss":{"cve":"CVE-2019-1851","score":0.01101,"percentile":0.65696,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
