Other versions may also be affected.


- [A] Local File Inclusion

[-] Risk: high
[-] File affected: index.php

This bug allows a guest to include a local file.

...

$static = false;

if(!isset($_GET['p'])) {
        $include = "./pages/news.php";
} else {
        $include = "./pages/" . $_GET['p'] . ".php";
}

...

if(!$static) {
        include($include);
}

...


- [B] File Disclosure

[-] Risk: medium
[-] File affected: index.php

This bug allows a guest to view the content of a
local file.

...

if(isset($_GET['s'])) {
        $static = true;
        $include = "./pages/custom/" . $_GET['s'] . ".html";
}

...

if(!$static) {
        include($include);
} else {
        $pageSmarty = new Smarty;
        $pageSmarty->assign('html', file_get_contents($include));
        
...


- [C] Blind SQL Injection

[-] Risk: medium
[-] File affected: news.php, register.php

These bugs allows a guest to inject SQL statements
into the affected queries.


- [D] SQL Injection

[-] Risk: high
[-] File affected: register.php

This bug allows a guest to inject SQL statements
into the affected query.

...

$result = mysql_query(sprintf("SELECT `uname`,`verified` FROM `users` WHERE 
`verifyHash`='%s' LIMIT 1;", $_GET['v'])) or die(mysql_error());
        if(mysql_numrows($result) != 1) {
                $msg = "Invalid verification hash! If you followed the link you 
received in your email please contact an admin and request a new verification 
email.";
        } else {
                $msg = "User " . mysql_result($result, 0, 'uname') . " 
successfully verified! you may now login using the form on the main page!";
        }
