[+] Bugs

The following flaws are tested on version 0.1.2.
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!";
	}
