CVE-2020-3242Network attack vector

API key disclosure via overbroad REST response

Published Jun 18, 2020 · Updated Nov 15, 2024

Information disclosure in Cisco UCS Director before 6.7.4.0 allows remote authenticated users to obtain another user’s API key. The REST API includes confidential fields in a crafted request’s response instead of limiting the response to data authorized for the requesting administrator. Administrative privileges are required, and the exposed key permits impersonation of the affected account.
