CVE-2017-6701
CWE-79
Summary
A vulnerability in the web application interface of the Cisco Identity
Services Engine (ISE) portal could allow an unauthenticated, remote
attacker to conduct a stored cross-site scripting (XSS) attack against a
user of the web interface of an affected system.
The vulnerability is due to insufficient sanitization of user-supplied data
that is written to log files and displayed in certain web pages of the web
interface of an affected device. An attacker could exploit this
vulnerability by successfully registering to a device and injecting script
code as part of a user-supplied value during the registration process. An
attacker could convince an administrator to visit an affected page or view
an affected log file to exploit the vulnerability. The injected script code
would be executed in the affected user's browser within the security
context of the affected device.
For additional information about cross-site scripting attacks and the
methods used to exploit these vulnerabilities, see the Cisco Applied
Mitigation Bulletin Understanding Cross-Site Scripting (XSS) Threat Vectors.
There are no workarounds that address this vulnerability.

CVE-2017-6605
CWE-79
Summary
A vulnerability in the web-based management interface of Cisco Identity
Services Engine (ISE) could allow an authenticated, remote attacker to
conduct a reflective 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.

available at the following links:
