A vulnerability in the web-based management interface of Cisco Prime Network Control System could allow an authenticated remote attacker to conduct a stored cross-site scripting (XSS) attack against a user of the web interface of the affected system. The vulnerability is due to insufficient validation of user-supplied input by the web-based management interface of an affected device. An attacker could exploit this vulnerability by persuading a user of the interface to click a malicious link. A successful exploit could allow the attacker to execute arbitrary script code in the context of the web-based management interface or allow the attacker to access sensitive browser-based information.
