DESCRIPTION:
Kacper has discovered some vulnerabilities in PHProjekt, which can be
exploited by malicious people to compromise a vulnerable system.

Input passed to the "path_pre" parameter in lib/specialdays.php and
to the "lib_path" parameter in lib/dbman_filter.inc.php is not
properly verified before being used to include files. This can be
exploited to include arbitrary files from local or external
resources.

The vulnerabilities have been confirmed in version 5.1. Other
versions may also be affected.

SOLUTION:
Edit the source code to ensure that input is properly verified.
