To exploit this vulnerability, an attacker would need to have a valid administrator account on an affected device.\r\n\r\nThe vulnerability is due to incorrect privilege assignment. An attacker could exploit this vulnerability by logging in to the system with a crafted Active Directory account. A successful exploit could allow the attacker to obtain root privileges on an affected device.\r\n\r\nNote: Only devices that have the CLI configured to support Active Directory authentication are affected by this vulnerability. CLI support for Active Directory authentication is disabled by default. All other uses of Active Directory Domain Services or Active Directory Certificate Services within ISE are not affected.\r\n\r\nCisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.\r\n\r\nThis advisory is available at the following link:\r\nhttps://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ise-priv-esc-fNZX8hHj [\"https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ise-priv-esc-fNZX8hHj\"]",
