A vulnerability in the Extensible Authentication Protocol-Transport Layer Security (EAP-TLS) certificate validation during EAP authentication for the Cisco Identity Services Engine (ISE) could allow an unauthenticated, remote attacker to cause the ISE application server to restart unexpectedly, causing a denial of service (DoS) condition on an affected system. The vulnerability is due to incomplete input validation of the client EAP-TLS certificate. An attacker could exploit this vulnerability by initiating EAP authentication over TLS to the ISE with a crafted EAP-TLS certificate. A successful exploit could allow the attacker to restart the ISE application server, resulting in a DoS condition on the affected system. The ISE application could continue to restart while the client attempts to establish the EAP authentication connection. • http://www.securityfocus.com/bid/104212 http://www.securitytracker.com/id/1040922 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20180516-iseeap • CWE-295: Improper Certificate Validation •

A vulnerability in the support tunnel feature of Cisco Identity Services Engine (ISE) could allow an authenticated, local attacker to access the device's shell. The vulnerability is due to improper configuration of the support tunnel feature. An attacker could exploit this vulnerability by tricking the device into unlocking the support user account and accessing the tunnel password and device serial number. A successful exploit could allow the attacker to run any system command with root access. This affects Cisco Identity Services Engine (ISE) software versions prior to 2.2.0.470. • http://www.securitytracker.com/id/1040717 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20180418-ise • CWE-16: Configuration •

A vulnerability in the web-based management interface of Cisco Identity Services Engine (ISE) could allow an unauthenticated, remote attacker to conduct a cross-site request forgery (CSRF) attack and perform arbitrary actions on an affected device. The vulnerability is due to insufficient CSRF protections for the web-based management interface of an affected device. An attacker could exploit this vulnerability by persuading a user of the interface to follow a crafted link. A successful exploit could allow the attacker to perform arbitrary actions on a targeted device via a web browser and with the privileges of the user.

A vulnerability in specific CLI commands for the Cisco Identity Services Engine (ISE) could allow an authenticated, local attacker to perform command injection to the underlying operating system or cause a hang or disconnect of the user session. The attacker needs valid administrator credentials for the device. The vulnerability is due to incomplete input validation of user input for certain CLI ISE configuration commands. An attacker could exploit this vulnerability by authenticating as an administrative user, issuing a specific CLI command, and entering crafted, malicious user input for the command parameters. An exploit could allow the attacker to perform command injection to the lower-level Linux operating system. • http://www.securityfocus.com/bid/103347 http://www.securitytracker.com/id/1040471 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20180307-ise6 • CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') •
