Product & Service Introduction:  
===============================  
Banana Dance is an open-source PHP/MySQL-based program. It is designed to combine the simplicity of wiki-publishing   
software with the versatility of a CMS. The program also promotes community-building through organized and   
user-rated commenting features. Highly flexible with theme-integration and extension availability Banana Dance   
can be used for all types of purposes, whether it be to create an entire website, a product owner`s manual, or   
an `article`-posting site.

Technical Details & Description:  
================================  
1.1  
A sql injection web vulnerability has been discovered in the official Lazarus Guestbook v1.22 content management system.  
The vulnerability allows an attacker to inject sql commands by usage of a vulnerable value to compromise the application dbms.  
  
The sql injection web vulnerability is located in the `db_prefix` value of the `inserts.php` files. Remote attackers and local low privileged user accounts are   
able to inject own sql commands by usage of vulnerable `db_prefix` value in the insert POST method request. A successful attack requires   
to manipulate a POST method request with vulnerable `db_prefix` value. The injection is a classic order-by sql injection web vulnerability.  
  
The security risk of the sql injection vulnerability is estimated as high with a cvss (common vulnerability scoring system) count of 8.1.  
Exploitation of the application-side web vulnerability requires no privileged web-application user account and no user interaction.  
Successful exploitation of the security vulnerability results in content management system compromise and database management system compromise.  
  
Request Method(s):  
[+] POST  
  
Vulnerable Module(s):  
[+] Insert  
  
Vulnerable Files(s):  
[+] inserts.php  
  
Vulnerable Parameter(s):  
[+] db_prefix  
  
  
1.2  
A local file include web vulnerability has been discovered in the official iFileExplorer v6.51 iOS mobile web-application.  
The local file include web vulnerability allows remote attackers to unauthorized include local file/path requests or system specific   
path commands to compromise the mobile web-application.  
  
The vulnerability is located in the `path` value of the mysql module in the `tables.php` file. Local attackers are able to manipulate   
the `path` value of the `mysql/tables.php` file. The execution of unauthorized local file or path request occurs in the same path   
location of the tables.php file.The request method to inject is POST and the attack vector is located on the application-side of   
the affected content management system.  
  
The security risk of the local file include web vulnerability is estimated as high with a cvss (common vulnerability scoring system) count of 7.3.   
Exploitation of the local file include web vulnerability requires no user interaction and a low privileged web-application user account.   
Successful exploitation of the local file include web vulnerability results in content management system compromise and database management system compromise.  
  
Vulnerable Method(s):  
[+] [POST]  
  
Vulnerable File(s):  
[+] /mysql/tables.php  
  
Vulnerable Module(s):  
[+] /mysql/  
  
Vulnerable Parameter(s):  
[+] path  
  
Affected Module(s):  
[+] /setup/mysql/tables.php  
  
  
Proof of Concept (PoC):  
=======================  
1.1 SQL Injection  
The sql injection vulnerability can be exploited by remote attackers without privileged application user account and user interaction.  
For security demonstration or to reproduce the vulnerability follow the provided information and steps below to continue.  
  
Vulnerable Source:  
  
$q11 = mysql_query(" INSERT INTO `" . $_POST['db_prefix'] . "users`  
(`id`, `username`, `password`, `salt`, `email`, `name`, `options`,  
`type`, `ip`, `joined`,  
  
`last_updated`, `upvoted`, `downvoted`) VALUES (1, '" .  
addslashes($_POST['username']) . "', '" . $encode_pass . "', '" .  
$salt . "', '" . addslashes($_POST['email']) . "',  
  
'Master Administrator', '', 1, '" . $_SERVER['REMOTE_ADDR'] . "', '" .  
$date . "', '" . $date . "', 0, 0); "); // inserts.php  
  
Note: Execution of the sql command occurs after usage of a send POST method request with the "db_prefix" and payload  
  
  
1.2 File Inclusion  
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 vulnerability follow the provided information and steps below to continue.  
  
Vulnerable File(s): /setup/complete.php  
  
Vulnerable Source:  
$mysql1 = $_POST['path'] . "/setup/mysql/tables.php";  
require $mysql1; // tables.php  
  
Note: Execution of the payload occurs after the send POST method request called the vulnerable `path` that includes  
  
PoC: /../../../file/we/want/to/include.php%00setup/mysql/tables.php  
  
  
Security Risk:  
==============  
1.1  
The security risk of the sql injection web vulnerability in the `db_prefix` is estimated as critical.  
  
1.2  
The security risk of the local file include web vulnerability in the path value is estimated as high.
