bypass authentication and execute arbitrary actions on an affected device.
The vulnerability is due to a failure in the software to perform proper
authentication. An attacker could exploit this vulnerability by browsing to
one of the hosted URLs in Cisco DCNM. A successful exploit could allow the
attacker to interact with and use certain functions within the Cisco DCNM.
Cisco has released software updates that address the vulnerability
described in this advisory. There are no workarounds that address this
vulnerability.
