Cisco Prime Data Center Network Manager Upload Servlet Path Traversal and Remote Code Execution Vulnerability

A vulnerability in the File Upload servlet of Cisco Prime Data Center Network Manager (DCNM) could allow an unauthenticated, remote attacker to upload arbitrary files to any directory of a vulnerable device and then execute those files.

The vulnerability is due to improper input validation of the parameters in the HTTP request and a processing error in the role-based access control (RBAC) of URLs. An attacker could exploit this vulnerability by uploading a crafted Java Server Pages (JSP) file to a specific folder using path traversal techniques and then executing that file remotely. An exploit could allow the attacker to execute arbitrary commands on the affected device with the privileges of the SYSTEM user.
