Title: PHPMyExplorer Arbitrary File Disclosure Vulnerability

Severity: HIGH

Description:

PHPMyExplorer is a free application that provides a web user interface for managing web content on a host. It works with Apache for Microsoft Windows systems and also on Linux platforms.

An input validation problem exists with PHPMyExplorer. It is possible for a user to browse the filesystem of the host by specially crafting a URL using variations of '../' sequences to break out of wwwroot. The '../' sequences must be appended as parameters for 'index.php?chemin='.

For example:

http://server//index.php?chemin=..%2F..%2F..%2F..%2F..%2F..%2F%2Fetc

As a result the attacker will be able to display arbitrary web-readable files, potentially disclosing sensitive information about the host.
