CVE-2017-6733
CWE-79
Summary
A vulnerability in the web-based 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 input validation and
output-encoding parameters for data that is passed between an affected
client and server. An attacker could exploit this vulnerability by
intercepting targeted user packets and injecting malicious code into the
targeted traffic stream. A successful exploit could allow the attacker to
inject script code into the HTTP flow between the targeted user and the
affected system.
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
and the OWASP reference page Cross-site Scripting (XSS).
There are no workarounds that address this vulnerability.

CVE-2017-6734
CWE-79
Summary
A vulnerability in the web-based management interface of Cisco Identity
Services Engine (ISE) Software could allow an authenticated, remote
attacker to conduct a cross-site scripting (XSS) attack against a user of
the web interface of an affected device.
The vulnerability is due to insufficient validation of user-supplied input
by the web-based management interface of the affected software. 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.
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
and the OWASP reference page Cross-site Scripting (XSS).
