CVE-2021-34702Network attack vector

Configuration disclosure via improper administrator privilege enforcement

Published Oct 6, 2021 · Updated Nov 7, 2024

Information disclosure in Cisco Identity Services Engine allows remote authenticated users to read system configuration data. The web-based management interface fails to enforce administrator privilege levels when serving a page containing low-value sensitive data. Read-only administrator access is sufficient to browse to the page and collect configuration details, with no reported integrity or availability impact.
