Summary
Multiple vulnerabilities in the web-based management interface of Cisco Identity Services Engine (ISE) guest portals could allow an authenticated, remote attacker to conduct cross-site scripting (XSS) attacks against a user of the interface.
These vulnerabilities are due to insufficient validation of user-supplied input by the web-based management interface of an affected system. An attacker could exploit these vulnerabilities by injecting malicious code into specific pages of the interface.
A successful exploit could allow the attacker to execute arbitrary script code in the context of the affected interface or access sensitive, browser-based information. To exploit these vulnerabilities, the attacker must have valid administrative credentials.
Cisco has released software updates that address these vulnerabilities. There are no workarounds that address these vulnerabilities.
Affected product named by the advisory: Cisco Identity Services Engine Software.
