Affects: TFTPUtil GUI versions 1.2.0 and 1.3.0
Fixed in: 1.4.0
Risk: Medium
Vulnerability Description: TFTPUtil GUI versions 1.2.0 and 1.3.0 are prone to a directory-traversal vulnerability because it fails to sanitize TFTP GET requests. By using a specially crafted TFTP GET request an attacker is capable of retrieving files outside of the TFTP root directory.
Impact: The ability to obtain files outside of the TFTP root directory may allow an attacker to obtain more information about the underlying operating system and applications running on the host.
