Description

Multiple vulnerabilities in the web-based management interface of Cisco Data Center Network Manager (DCNM) could allow an authenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the interface on an affected device. These vulnerabilities are due to insufficient validation of user-supplied input by the web-based management interface. An attacker could exploit these vulnerabilities by persuading a user of the interface to click a customized link. A successful exploit could allow the attacker to execute arbitrary script code in the context of the interface or access sensitive browser-based information.
