which can be exploited by malicious users to gain knowledge of
certain system information and to perform certain actions on the
vulnerable system.

1) An input validation error in the MKD command allows users to
create arbitrary folders outside of the FTP root via directory
traversal attacks.

2) An error in the processing of the REN command allows for the
disclosure of the ALFTP server path.

The vulnerabilities are confirmed in version 4.1 beta 1.
