A vulnerability in the web-based management interface of Cisco Data Center Network Manager (DCNM) could allow an unauthenticated, remote attacker to upload arbitrary files on an affected device. The vulnerability is due to incorrect permission settings in affected DCNM software. An attacker could exploit this vulnerability by uploading specially crafted data to the affected device. A successful exploit could allow the attacker to write arbitrary files on the filesystem and execute code with root privileges on the affected device.
Weaknesses in this category are related to the management of permissions, privileges, and other security features that are used to perform access control.
The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.
