Name of the Vulnerable Software and Affected Versions Cisco Identity Services Engine (ISE) Software (affected versions not specified)

Description A vulnerability in the web-based management interface of Cisco Identity Services Engine (ISE) Software could allow an authenticated, remote attacker with administrative credentials to conduct a cross-site scripting (XSS) attack against a user of the interface. This issue exists because the web-based management interface does not properly validate user-supplied input. An attacker could exploit this by injecting malicious code into specific pages of the interface, potentially allowing the execution of arbitrary script code in the context of the interface or access to sensitive, browser-based information. The attacker would need valid administrative credentials to exploit this vulnerability.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
