Extropia WebStore is an e-commerce shopping cart application consisting of routines for error handling, order processing, encrypted mailing, frames, Javascript and VBscript. The routine web_store.cgi does not properly handle the $file_extension variable if null characters are used. For example if the following URL was requested, the file in question would not be delivered to the user: http://target/cgi-bin/Web_Store/web_store.cgi?page=../../../path/filename.ext However, by using the escaped character "%00", the requested file would be accessed successfully: http://target/cgi-bin/Web_Store/web_store.cgi?page=../../../path/filename%00ext Successful exploitation could lead to a remote intruder gaining read access to any known file.
