CVE-2018-0211
CWE-20

Summary

A vulnerability in specific CLI commands for the Cisco Identity Services
Engine could allow an authenticated, local attacker to cause a denial of
service (DoS) condition. The device may need to be manually rebooted to
recover.
The vulnerability is due to lack of proper input validation of the CLI user
input for certain CLI commands. An attacker could exploit this vulnerability
by authenticating to the device and issuing a crafted, malicious CLI command
on the targeted device. A successful exploit could allow the attacker to cause
a DoS condition. The attacker must have valid administrative privileges on the
device to exploit this vulnerability.
There are no workarounds that address this vulnerability.

CVE-2018-0212
CWE-79

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 scripting (XSS) attack against a user of the web-based
management interface of an affected device.
The vulnerability is due to insufficient validation of user-supplied input by
the web-based management interface of an affected device. An attacker could
exploit this vulnerability by persuading a user of the interface to click a
crafted link. A successful exploit could allow the attacker to execute
arbitrary script code in the context of the interface or allow the attacker to
access sensitive browser-based information.
There are no workarounds that address this vulnerability.

CVE-2018-0221
CWE-78

Summary

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. It is also possible the attacker
could cause the ISE user interface for this management session to hang or
disconnect.
There are no workarounds that address this vulnerability.
