High


Technical Details & Description:
================================
1.1
A remote sql injection web vulnerability has been discovered in the Iranian Web 
Blog Service v3.3 content management system.
The vulnerability allows remote attackers to execute own sql commands to 
compromise the web-applicaation or connected dbms.

The vulnerability is located in the `i` parameter of the `list.php` file GET 
method request. Remote attackers are able 
to execute sql commands by injection of malicious statements via GET method 
request. The vulnerability is located on the 
application-side and the request method to inject/execute is GET. The security 
vulnerability is a classic order by sql 
injection in the `i` value. 

The security risk of the sql injection vulnerability is estimated as high with 
a cvss (common vulnerability scoring system) count of 7.4.
Exploitation of the remote sql injection web vulnerability requires no user 
interaction or privileged web-application user account.
Successful exploitation of the remote sql injection results in database 
management system, web-server and web-application compromise.

Request Method(s):
                                [+] GET

Vulnerable File(s):
                                [+] list.php

Vulnerable Parameter(s):
                                [+] i




1.2
A client-side cross site scripting web vulnerability has been discovered in the 
Iranian Web Blog Service v3.3 content management system.
The web vulnerability allows remote attackers to inject own malicious script 
codes to the client-side of the online service module or function.

The cross site scripting web vulnerability is located in the `page` parameter 
of the `list.php` file GET method request. Remote attackers are 
able to inject own malicious script codes to the page parameter to compromise 
client-side requests. The attack vector of the vulnerability is 
non-persistent and the request method to inject/execute is GET.

The security risk of the cross site web vulnerability is estimated as medium 
with a cvss (common vulnerability scoring system) count of 3.3. 
Exploitation of the web vulnerability requires no privileged web-application 
account with restricted access and only low user interaction. 
Successful exploitation of the vulnerabilities results in persistent phishing, 
session hijacking, persistent external redirect to malicious 
sources and application-side manipulation of affected or connected module 
context.

Request Method(s):
                                [+] GET

Vulnerable Module(s):
                                [+] list.php

Vulnerable Parameter(s):
                                [+] page




1.3
An arbitrary file upload web vulnerability has been discovered in the Iranian 
Web Blog Service v3.3 content management system.
The vulnerability allows to upload malicious files to unrestricted path 
variables to compromise the web-server or database.

The web vulnerability is located in the connector path of the fckeditor module. 
Remote attackers are able to upload files without 
secure authentication, which results in the compromise by malicious webshells 
(php or js). The path variable of the upload folder 
is not restricted by default configuration.

The security risk of the web vulnerability is estimated as high with a cvss 
(common vulnerability scoring system) count of 7.1. 
Exploitation of the web vulnerability requires no privileged web-application 
account with restricted access or user interaction. 
Successful exploitation of the vulnerabilities results in unauthorized upload 
of files like webshells or rootkits to compromise the 
web-server and database management system.

Request Method(s):
                                [+] POST

Vulnerable Module(s):
                                [+] Fckeditor

Vulnerable Function(s):
                                [+] File Upload


Proof of Concept (PoC):
=======================
1.1
The remote sql-injection web vulnerability can be exploited by remote attackers 
without privileged user account or user interaction.
For security demonstration or to reproduce the vulnerability follow the 
provided information and steps below to continue.

Dork(s):
inurl:list.php?i=

PoC:
http://localhost:8080/list.php?i=-1'[SQL-INJECTION VULNERABILITY!]---



1.2
The cross site scripting web vulnerability can be exploited by remote attackers 
without privileged user account and with low user interaction.
For security demonstration or to reproduce the vulnerability follow the 
provided information and steps below to continue.

PoC:
http://localhost:8080/list.php?page=37<script>alert(document.cookie)</script>



1.3
The arbitrary file upload web vulnerability can be exploited by remote 
attackers without privileged user account or user interaction.
For security demonstration or to reproduce the vulnerability follow the 
provided information and steps below to continue.


PoC:
http://localhost:8080/fckeditor/editor/filemanager/connectors/
http://localhost:8080/fckeditor/editor/filemanager/connectors/uploadtest.html


Solution - Fix & Patch:
=======================
1.1
The first vulnerability can be patched by a secure parse and encode of the 
vulnerable i parameter in the list.php file GET method request.
Escape and use a prepared statement to secure the sql request in the code-line 
of the file.

1.2
Encode and parse the vulnerable page parameter in the list.php file GET method 
request. Disallow the usage of special chars to prevent client-side xss attacks.
Restrict the parameter input and encode the value or escape the entries.

1.3
Restrict the file path request and disallow uploads to prevent arbitrary file 
upload attacks. 
Disallow to review the path after upload to prevent the execute of webshells.


Security Risk:
==============
1.1
The security risk of the remote sql-injection web vulnerability in the i 
parameter value of the list.php file is estimated as high. (CVSS 7.4)

1.2
The security risk of the cross site scripting web vulnerability in the page 
parameter value of the list.php file is estimated as medium. (CVSS 3.3)

1.3
The security risk of the arbitrary file upload web vulnerability in the 
fckeditor module is estimated as high. (CVSS 7.1)
