The vulnerability is due to incorrect allocation of the enable/disable action button under the role-based access control code on an affected system. An attacker could exploit this vulnerability by authenticating as a read-only user and then updating the roles of other users to disable them. A successful exploit could allow the attacker to disable users, including administrative users.","severity":{"version":"3.0","score":4.3,"vector":"CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N","level":"medium","assessor":"cna","from":"cve"},"epss":{"day":"2026-11-09","score":0.00675,"percentile":0.52477,"model":"v2026.06.15"},"facts":{"in_kev":false,"known_exploited":false,"public_exploit":false,"fix_available":false},"cwes":["CWE-284"],"published":"2020-05-06T16:40:52Z","modified":"2026-06-17T03:17:58Z","products":[{"vendor":"cisco","product":"cisco ucs director"},{"vendor":"cisco","product":"integrated_management_controller_supervisor"},{"vendor":"cisco","product":"ucs_director"},{"vendor":"cisco","product":"ucs_director_express_for_big_data"}],"references":[{"url":"https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ucsd-Ar6BAguz","tags":["vendor-advisory","x_refsource_CISCO","x_transferred","Vendor Advisory"]},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2020-3329"},{"url":"https://github.com/advisories/GHSA-r92q-j6h7-wh5j"}],"sources":{"cve":[{"id":"CVE-2020-3329","title":"Cisco IMC Supervisor, Cisco UCS Director, and Cisco UCS Director Express for Big Data Role-Based Access Control Vulnerability","description":"A vulnerability in role-based access control of Cisco Integrated Management Controller (IMC) Supervisor, Cisco UCS Director, and Cisco UCS Director Express for Big Data could allow a read-only authenticated, remote attacker to disable user accounts on an affected system.
