"According to its self-reported version, Cisco Identity Services Engine Software is affected by a cross-site scripting
(XSS) vulnerability. The vulnerability exists because the web-based management interface does not properly validate
user-supplied input. An authenticated, remote attacker could exploit this vulnerability 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 interface or access sensitive, browser-based information. To exploit this vulnerability, an attacker
would need to have valid administrative credentials.

Please see the included Cisco BIDs and Cisco Security Advisory for more information.");
