CVE-2021-34702: Cisco Security Advisory: Cisco Identity Services Engine Sensitive Information Disclosure Vulnerability
A vulnerability in the web-based management interface of Cisco Identity Services Engine (ISE) could allow an authenticated, remote attacker to obtain sensitive information. This vulnerability is due to improper enforcement of administrator privilege levels for low-value sensitive data. An attacker with read-only administrator access to the web-based management interface could exploit this vulnerability by browsing to the page that contains the sensitive data. A successful exploit could allow the attacker to collect sensitive information regarding the configuration of the system.
When considering software upgrades, customers are advised to regularly consult the advisories for Cisco products, which are available from the Cisco Security Advisories page, to determine exposure and a complete upgrade solution.
In all cases, customers should ensure that the devices to be upgraded contain sufficient memory and confirm that current hardware and software configurations will continue to be supported properly by the new release. If the information is not clear, customers are advised to contact the Cisco Technical Assistance Center (TAC) or their contracted maintenance providers.
