Summary
o Multiple vulnerabilities in the web-based management interface of Cisco
Identity Services Engine (ISE) could allow an unauthenticated, remote
attacker to conduct a stored cross-site scripting (XSS) attack or a
reflected cross-site scripting (XSS) attack against a user of the web-based
management interface of an affected device.
For more information about these vulnerabilities, see the Details section
of this security advisory.
There are no workarounds that address these vulnerabilities.
This advisory is available at the following link:

cisco-sa-20190109-ise-multi-xss
Affected Products
o Vulnerable Products
These vulnerabilities affect Cisco Identity Services Engine (ISE). For
information about affected software releases, consult the Cisco bug IDs at
the top of this advisory.
Products Confirmed Not Vulnerable
Only products listed in the Vulnerable Products section of this advisory
are known to be affected by this vulnerability.
Details
o Two vulnerabilities in the web-based management interface of Cisco Identity
Services Engine (ISE) could allow an unauthenticated, remote attacker to
conduct a stored cross-site scripting (XSS) attack or a reflected
cross-site scripting (XSS) attack against a user of the web-based
management interface of an affected device.
The vulnerabilities are not dependent on one another; exploitation of one
of the vulnerabilities is not required to exploit the other vulnerability.
In addition, a software release that is affected by one of the
vulnerabilities may not be affected by the other vulnerability.
Details about the vulnerabilities are as follows.
Cisco Identity Services Engine Stored Cross-Site Scripting Vulnerability
A vulnerability in the web-based management interface of Cisco Identity
Services Engine (ISE) 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-based management interface of an affected device. An attacker could
exploit this vulnerability by convincing a user of the interface to click a
specific link or view an affected log file. The injected script code may be
executed in the context of the web-based management interface or allow the
attacker to access sensitive browser-based information.
The CVE ID for this vulnerability is: CVE-2018-15440
The Security Impact Rating (SIR) for this vulnerability is: Medium
Cisco Identity Services Engine Reflected Cross-Site Scripting Vulnerability
A vulnerability in the web-based management interface of Cisco Identity
Services Engine (ISE) could allow an unauthenticated, remote attacker to
conduct a reflected cross-site scripting (XSS) attack against a user of the
web-based interface.
The vulnerability is due to insufficient input validation of some
parameters passed to the web-based management interface of an affected
device. An attacker could exploit this vulnerability by convincing a user
of the interface to click a specific link. A successful exploit could allow
the attacker to execute arbitrary script code in the context of the
web-based management interface or allow the attacker to access sensitive
browser-based information.
The CVE ID for this vulnerability is: CVE-2018-15463
The Security Impact Rating (SIR) for this vulnerability is: Medium
Workarounds
o There are no workarounds that address these vulnerabilities.
Fixed Software
o For information about fixed software releases, consult the Cisco bug ID(s)
at the top of this advisory.
When considering software upgrades, customers are advised to regularly
consult the advisories for Cisco products, which are available from the
Cisco Security Advisories and Alerts page , to determine exposure and a
complete upgrade solution.
In all cases, customers should ensure that the devices to be upgraded
contain sufficient memory and confirm that current hardware and software
configurations will continue to be supported properly by the new release.
If the information is not clear, customers are advised to contact the Cisco
Technical Assistance Center (TAC) or their contracted maintenance
providers.
Exploitation and Public Announcements
o The Cisco Product Security Incident Response Team (PSIRT) is aware of the
existence of public exploit code targeting the vulnerabilities that are
described in this advisory.

Cisco Identity Services Engine Password Recovery Vulnerability
Importance: Medium
Advisory ID: cisco-sa-20190109-ise-passwd
First Published: 2019 January 9 16:00 GMT
Version 1.0: Final
Workarounds: No workarounds available

CVE-2018-15456
CWE-200
CVSS Score: Base 4.3
CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N/E:X/RL:X/RC:X
Summary
o
A vulnerability in the Admin Portal of Cisco Identity Services Engine (ISE)
could allow an authenticated, remote attacker to view saved passwords in
plain text.
The vulnerability is due to the incorrect inclusion of saved passwords when
loading configuration pages in the Admin Portal. An attacker with read or
write access to the Admin Portal could exploit this vulnerability by
browsing to a page that contains sensitive data. An exploit could allow the
attacker to recover passwords for unauthorized use and expose those
accounts to further attack.
There are no workarounds that address this vulnerability.
