A vulnerability in the directory permissions of Cisco Enterprise NFV Infrastructure Software (NFVIS) could allow an authenticated, remote attacker to perform a directory traversal attack on a limited set of restricted directories.
The vulnerability is due to a flaw in the logic that governs directory permissions. An attacker could exploit this vulnerability by using capabilities that are not controlled by the role-based access control (RBAC) mechanisms of the software. A successful exploit could allow the attacker to overwrite files on an affected device.
Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.
