DESCRIPTION:
Nuno Justo has discovered a vulnerability in AnyPortal(php), which
can be exploited by malicious users to disclose and manipulate
sensitive information, and compromise a vulnerable system.

sanitised before being used to create, edit, or view files. This can
be exploited to disclose or manipulate the content of arbitrary files
via directory traversal attacks.
