-
A vulnerability in the Cisco Identity Services Engine (ISE) Infra Admin UI could allow an unauthenticated, remote attacker to perform a cross-site scripting (XSS) attack.
The vulnerability is due to insufficient input validation of some parameters passed via HTTP GET or POST methods. An attacker could exploit this vulnerability by intercepting the user packets and injecting malicious code. An exploit could allow the attacker to execute arbitrary script code in the context of the affected site or allow the attacker to access sensitive browser-based information.
Cisco has confirmed the vulnerability and released software updates.
To exploit the vulnerability, the attacker may provide a link that directs a user to a malicious site and use misleading language or instructions to persuade the user to follow the provided link.
Cisco indicates through the CVSS score that functional exploit code exists; however, the code is not known to be publicly available.
-
Cisco has released bug ID CSCus16052 for registered users, which contains additional details and an up-to-date list of affected product versions.

Administrators are advised to apply the appropriate updates.
Users should verify that unsolicited links are safe to follow.
For additional information about XSS attacks and the methods used to exploit these vulnerabilities, see the Cisco Applied Mitigation Bulletin Understanding Cross-Site Scripting (XSS) Threat Vectors.
Administrators are advised to monitor affected systems.
