Cisco Data Center Network Manager Arbitrary File Upload and Remote Code Execution Vulnerability
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.
