Introduction:
=============
vOlk-Botnet v4.0 is a remote administration tool, its main function is to manage the HOSTS file of the windows 
operating systems The code created by [byvOlk] PHP and Visual Basic 6.0.

Features:
[+] Add Startup
[+] Download & Execute.

Abstract:
=========
The Vulnerability Laboratory Research Team discovered multiple vulnerabilities in the vOlk-Botnet framework application 
v4.0 private edition.

Severity:
=========
Critical


Details:
========
1.1
The vulnerability laboratory research team discovered multiple sql injection vulnerabilities in the vOlk-Botnet 
framework application v4.0 private edition.
The sql vulnerabilities allow remote attackers to inject/execute own sql commands/statements on the affected vOlks 
botnet application control panel dbms.
The vulnerabilities are located in the Messenger, Filezilla, Estadisticas files with the bound vulnerable ?pag listing 
parameter. The vulnerability can 
be exploited by remote attackers without required user inter action. Successful exploitation of the vulnerabilities 
result in botnet control panel 
compromise via remote sql injection attack.

Vulnerable Files(s):
                                [+] Messenger.php
                                [+] Filezilla.php
                                [+] Estadisticas.php

Vulnerable Parameter(s):
                                [+] pag


1.2
The vulnerability laboratory research team discovered multiple persistent web vulnerabilities in the vOlk-Botnet 
framework application v4.0 private edition.
The input validation vulnerabilities allow remote attackers to inject own malicious persistent script code on 
application side of the botnet framework.
The vulnerabilities are located in the Visit Webpage (Open URL), MSN Stealer, Download File and Setting modules with 
the bound vulnerable domin, 
Pasw, https or messenger bot s name parameters. The vulnerability can be exploited by remote attacker with low or 
medium required user inter action. 
Successful exploitation of the vulnerabilities result in botnet control panel compromise via session hijacking, 
persistent web context manipulation or 
combined csrf request manipulation.

Vulnerable Module(s):
                                [+] MSN Stealer

                                [+] Setting

Vulnerable Parameter(s):
                                [+] Name -  Bot s Name
                                [+] URL - Open URL Bots

Proof of Concept:
=================
1.1
The sql injection vulnerabilities can be exploited by remote attacker without privileged application user account and 
without 
required user inter action. For demonstration or reproduce ...

1.2
The persistent script code inject vulnerabilities can be exploited by remote attackers without privileged application 
user account but with 
low or medium required user inter action. For demonstration or reproduce ...

MSN Stealer:
The msn stealer module inside of the application displays the Bot's Name unsanitized. To infect the attacker back the 
victim can simulate a 
fake msn account login on a infected system with malicious persistent script code as Bot's Name. The result is a 
persistent script code execution 
out of Bot's Name web context in the messenger listing. The victim can hijack the vOlks Botnet Panel sessions or 
manipulate the framework with 
own malicious persistent context to stop, block, take over or disable the service.
