Summary
o 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.
