Advisory: MiniNuke v2.x Multiple Remote Vulnerabilities
Author: Mustafa Can Bjorn "nukedx a.k.a nuker" IPEKCI
Date: 27/05/06 03:16 PM
ICQ: 10072
Vendor: MiniNuke ( (
Version: 2.3 and prior versions must be affected.
About: Via this method remote attacker can inject arbitrary SQL query  
to Your_Account.asp. The problem is that
yas_1,yas_2 and yas_3 parameters did not sanitized properly before  
using them on SQL query.This can be caused to remote
attacker could change the SQL query line and change his rights on MiniNuke.
Vulnerable codes can be found at lines 39-79..
yas = Request.Form("yas_1") & "." & Request.Form("yas_2") & "." &  
Connection.Execute("UPDATE MEMBERS SET yas = '"&yas&"' WHERE uye_id =  
Fixing this vulnerability is so easy change the line 39 to this.
yas = duz(Request.Form("yas_1")) & "." & duz(Request.Form("yas_2")) &  
"." & duz(Request.Form("yas_3"))
Another SQL injection in Your_Account.asp is that change theme for  
user, theme parameter did not sanitized properly before
using it on SQL query.
Vulnerable code can be found at line 229..
Connection.Execute("UPDATE MEMBERS SET  
u_theme='"&Request.Form("theme")&"' WHERE uye_id =  
Fixing this vulnerability is so easy change the line to this
fixedtheme = duz(Request.Form("theme"))
Connection.Execute("UPDATE MEMBERS SET u_theme='"&fixedtheme&"' WHERE  
uye_id = "&Session("Uye_ID")&"")
duz() function is special for MiniNuke it cleans the malicious  
characters on based variable.
Second problem is on membership.asp.The security code is made as text  
format so it can be easily readable by
remote attacker, and can be used for mass-register so mass-register  
can make D.o.S for MiniNuke.
Third problem is on enter.asp the gguvenlik and guvenlik parameters  
used in login can be changeable by remote attacker,
this can be cause remote attacker makes a dictionary-attack to specified user.
Level: Critical
Solution: Given
POST ->  
With this example remote attacker could make dictionary attack for  
getting victim's password.
POST ->  
And other example for SQL injection in yas params like this.
Login to your account on MiniNuke go to  
/Your_Account.asp?op=UpdateProfile and open the source code of page
find yas_3 and change value like YEAR',seviye='1 and edit source  
correctly dont forgot to edit Timeline:
* 27/05/2006: Vulnerability found.
* 27/05/2006: Contacted with vendor and waiting reply.
