A vulnerability in the REST API of Cisco Data Center Network Manager could allow an unauthenticated, remote attacker to bypass authentication and execute arbitrary actions with administrative privileges on an affected device. The vulnerability exists because different installations share a static encryption key. An attacker could exploit this vulnerability by using the static key to craft a valid session token. A successful exploit could allow the attacker to perform arbitrary actions through the. REST API. Cisco has released free software updates that address the vulnerability described in this advisory. There are no workarounds that address this vulnerability.”]
