Summary
o A vulnerability in the web-based management interface of Cisco Data Center
Network Manager (DCNM) could allow an authenticated, remote attacker with
administrative credentials to conduct a cross-site scripting (XSS) attack
against a user of the interface.
The vulnerability is due to insufficient input validation by the web-based
