Description
A vulnerability in the Localdisk Management feature of Cisco Identity Services Engine (ISE) could allow an authenticated, remote attacker to make unauthorized changes to the file system of an affected device.
This vulnerability is due to insufficient input validation. An attacker could exploit this vulnerability by sending a crafted HTTP request with absolute path sequences. A successful exploit could allow the attacker to upload malicious files to arbitrary locations within the file system. Using this method, it is possible to access the underlying operating system and execute commands with system privileges.

CWE-22
Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
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.
CWE-37
Path Traversal: '/absolute/pathname/here'
The product accepts input in the form of a slash absolute path ('/absolute/pathname/here') without appropriate validation, which can allow an attacker to traverse the file system to unintended locations or access arbitrary files.
