In \apps\phpsysinfo3.1.12/language/language.php

60: echo file_get_contents(APP_ROOT . '/language/' . $lang . '.xml');

is presented where $lang is defined as:

52: $lang = basename($_GET['lang']);

Which can be exploited like

localhost/phpsysinfo/language/language.php?lang=../../../stufftoinclude

which can be extended with nullbytes to contain any other file that isn't XML too.

Thanks,

language.php line 49: trim(htmlspecialchars(basename($_GET['lang']))).'.xml'))
truncate the name, chars like "../../../" are deleted.
Additionally fixed : 60b5bbb , the characters are now filtered.
