TOPo is a free TOP system written in PHP that works
without MySQL database.TOPo is specially designed for
web sites hosted in web servers that not offer a
quality MySQL support.
TOPo contains a flaw that allows a remote cross site
scripting attack.This flaw exists because the application
does not validate 'm','s','ID','t' and possible other parameters
upon submission to the 'index.php'script.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.
TOPo contains a flaw too that allow remote users to information
disclosure. All data are stored in '/data/' folder and all *.dat
files store all votes, comments and other information about the
site on top. Any user can download this files and obtain all
client ip address(all clients who are vote or added a comment)
