CVE-2023-20167: Cisco Security Advisory: Cisco Identity Services Engine Path Traversal Vulnerabilities
Multiple vulnerabilities in Cisco Identity Services Engine (ISE) could allow an authenticated attacker to perform path traversal attacks on the underlying operating system to either elevate privileges to root or read arbitrary files. To exploit these vulnerabilities, an attacker must have valid Administrator credentials on the affected device. For more information about these vulnerabilities, see the Details section of this advisory.
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.
