Technical details
A directory traversal vulnerability exists within the DashboardFileReceiveServlet component of Brocade Network Advisor. The servlet fails to properly validate user-supplied paths during file upload operations, allowing an attacker to escape the intended directory. By sending a specially crafted request, a remote, unauthenticated attacker can upload arbitrary files to executable locations on the file system. This can be leveraged to achieve remote code execution under the context of the SYSTEM account. The vulnerability is fixed in versions 14.0.3, 14.1.1, and later.
