Revision History: February 7 2019: Vendor added information regarding the existence of public exploit code for advisory id: cisco-sa-20190109-ise-multi-xss January 10 2019: Initial Release - --------------------------BEGIN INCLUDED TEXT-------------------- Cisco Identity Services Engine Multiple Cross-Site Scripting Vulnerabilities Priority: Medium Advisory ID: cisco-sa-20190109-ise-multi-xss First Published: 2019 January 9 16:00 GMT Last Updated: 2019 February 6 14:10 GMT Version 1.1: Final Workarounds: No workarounds available Cisco Bug IDs: CSCvm71860 CSCvm79609 CVE-2018-15440 CVE-2018-15463 CWE-79 CVSS Score: 6.1 AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N/E:X/RL:X/RC:X 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: https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/ 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. Source o Cisco would like to thank the independent security researcher Pedro Ribeiro for reporting the vulnerability identified as CVE-2018-15440 to Beyond Security's SecuriTeam Secure Disclosure program. Cisco would also like to thank application security consultant Olivier Arteau of Groupe Technologie Desjardins for reporting the vulnerability identified as CVE-2018-15463.

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.
