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.

Input passed to the "F" parameter in "siteman.php3" isn't properly 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.

The vulnerability has been confirmed in version 0.1. Other versions may also be affected.
