A vulnerability in the web-based management interface of Cisco Data Center Network Manager (DCNM) could allow an unauthenticated, remote attacker to gain access to sensitive files on an affected device. The vulnerability is due to incorrect permissions settings on affected DCNM software. An attacker could exploit this vulnerability by connecting to the web-based management interface of an affected device and requesting specific URLs. A successful exploit could allow the attacker to download arbitrary files from the underlying filesystem of 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.
