This is one of the tricky one...  I would say : depend of the
information display.  Exemple: if you can see the config file directory,
and you have others problem, like random file inclusion, it will be a
High... If it only give the name of the file, it might be Low, but
usally, you might have the same type of error elsewhere, so you need to
look around (maybe code audit) to decide.
