`Minihttpserver 1.x Host Engine Flaws
+ File-Sharing for NET:
"File Sharing for net is a complete, secure web server that shares your
business documents and files over the web: remote users only need
browsers to view your files. Share, transfer files securely with
+ Forums Web Server
"WebForums Server allows you to setup a bulletin board and photo/file
exchange web service. It offers a built in HTTP engine, internal
database engine, integrated HTML/Script pages, user management
interface, message board engine and a secure file Upload/Download
option. It is without a doubt the easiest and complet all in one Forum
Server software you have seen."
- Both Vendors Descriptions
Both products, in my opinion, deliver exactly what they offer, and are
definitely a reasonable buy for the price, remembering the fact that
you do not only get the scripts, but a well rounded webserver to boot.
However there is one aspect in which they are seriously lacking -
In light of Mr Dennis Rand's recent discovery of several dangerous
flaws within the server:
All of which (it is claimed) are fixed, you would have thought that
security would have become quite a priority for the development team,
but it appears this was not the case.
It took me about two minutes to find two more dangerous flaws which
can allow a remote user complete administrator access to the system
file/forum system and any file on the remote server.
These are not difficult, hard to find flaws, and I think even a few
minutes auditing would have turned both of these up immediately.
Flaw 1 - Directory Traversal:
This will allow the remote unauthenticated user to break free of the
webroot, and download any file on the system
The example file downloads the username and password file for both
applications, effectively allowing an intruder to access the vulnerable
system from the web based login page without any type of malformed
Flaw 2 - Login Parsing Flaw
When Web Forum Server is first installed, it is often possible to
gain administrator access to the forum by using the following login
I have managed to also login this way by typing ' admin" ' in the
password recovery box.
Operating system and servicepack level:
Windows 9x/Me/NT Based
+ Minihttpserver 1.x
+ Web Forum Server 1.x
+ File-Sharing NET 1.x
Under what circumstances the vulnerability was discovered:
By mistake pretty much - Testing some older vulns.
If the vendor has been notified:
Yes, the vendor had been notified.
