Paul M. Jones Phorecast Remote Arbitrary Code Execution Vulnerability

Phorecast is freely available, open-source web-based single-user email. It allows users to send and receive email through a web-based interface.

A problem exists in Phorecast that will allow a remote attacker to execute arbitrary code on a host running the software(with the privileges of the webserver process). It is possible to supply arbitrary data to the $include variable. As a result, the affected script may be redirected to execute arbitrary code located on an external host, as specified by the attacker.

This issue can be exploited if the remote attacker submits a maliciously crafted URL.
