Summary

  o A vulnerability 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 web-based
    management interface.

    The vulnerability is due to insufficient validation of user-supplied input
    by the web-based management interface. An attacker could exploit this
    vulnerability by persuading a user of the interface to click a crafted
    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.

    Cisco has released software updates that address this vulnerability. There
    are no workarounds that address this vulnerability.
