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.
