In addition, a software release that is affected by one of the vulnerabilities may not be affected by the other vulnerabilities.\r\n\r\nNote: These vulnerabilities can be exploited only by valid and authorized users of the Cisco ISE system. As a best practice, customers can restrict console access and admin web access. To configure the access restrictions, choose Administration \u003e System \u003e Admin Access \u003e Settings \u003e Access \u003e IP Access.\r\n\r\nDetails about the vulnerabilities are as follows:\r\n\r\nCVE-2023-20171: Cisco Identity Services Engine Arbitrary File Deletion Vulnerability\r\n\r\nA vulnerability in the web-based management interface of Cisco ISE could allow an authenticated, remote attacker to delete arbitrary files on an affected device.\r\n\r\nThis vulnerability is due to insufficient validation of user-supplied input. An attacker could exploit this vulnerability by sending a crafted HTTP request that contains certain character sequences to an affected system. A successful exploit could allow the attacker to delete specific files that their configured administrative level should not have access to.\r\n\r\nCisco has released software updates that address this vulnerability.

An attacker could exploit this vulnerability by submitting a crafted HTTP request to an affected system. A successful exploit could allow the attacker to either download or delete certain files that should be restricted. To exploit this vulnerability, an attacker would need valid read-only Administrator credentials.\r\n\r\nCisco has released software updates that address this vulnerability.
