A remote buffer overflow vulnerability affects Working Resources BadBlue. This issue is due to a failure of the application to securely copy GET request parameters into finite process buffers.
 
An attacker may leverage this issue to execute arbitrary code with the privileges of the affected Web server, facilitating a SYSTEM level compromise. 

/*
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

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.
