#Usage : Copy this script to idman2.pl #Execute : perl idman2.pl #Go to the file bof.txt , Select ALL , then Copy . # After copying the whole line Go To Downloads ---> Options ----> Dial up / VPN ----> paste the line into the username field and let the password field blank then click Enter . #French Version : Go to : Telechargement ---> Options ---> Internet ---> then Copy The Whole line from bof.txt and paste it into the username field and let the password field blank then click Enter .
# BETTER COPY THE CONTENT OF THE FILE USING NOTEPAD++ # First Of all , This is a different exploit from (Internet Download Manager - Stack Based Overflow Vulnerability.) # Second , Script Kiddies will be happy with my latest Idman Vulnerabilities but don't bother, you may face some problems with the shellcode in this exploit So choose wisely the badchars .

##########Universal Address############## # I worked on finding a universal address and that's what I found . # First you may find some pop r/pop r2/ret / call dword ptr SS:[R+30] addresses in idman.exe Module . # but The problem here is that all the addr in this module look like this : 0x00ffffff # So it will terminate the string and the vulnerability will not be executed . # Ok, the second problem is in idmmkb.dll we found an address "rebase" . As I analysed I found that the rebase goes between "a" and "b" in the address base # And the Top always stays the same . It will give us in this case two Possibilities 50% of each address to be the correct one in every program execution . # So All to do here is to try these two addresses manually or using a program . # The First one : 0x017A1B13 # The Second one : 0x017B1B13 # All you have to do is replace one of these in the "pointer to the next SE Handler" . ########################################
