The vulnerability is caused due to an input validation error making it possible to escape the FTP root and retrieve arbitrary files on the system via directory traversal attacks using the "../../" character sequence. The vulnerability has been confirmed in version r1.0.7 (build 45). Other versions may also be affected. SOLUTION: Filter malicious characters and character sequences in a FTP proxy. Grant only access to trusted users. The impact of directory traversal attacks can be lessened by placing the FTP root on a separate drive letter or by restricting access using NTFS.
