In 2N Access Commander versions 3.1.1.2 and prior, a Path Traversal vulnerability could allow an attacker with administrative privileges to write files on the filesystem and potentially achieve arbitrary remote code execution. This vulnerability cannot be exploited by users with lower privilege roles.
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.
