Fimap not detecting even test file inclusion bugs... #67

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
This error occurs on all test file inclusion bugs I have trialled.
Test example: http://localhost/inclusiondemo/lfi1.php?file=contactus.php

In this example the file= parameter is vulnerable to LFI, 
Example: http://localhost/inclusiondemo/lfi1.php?file=../../../../etc/passwd

However, fimap seems unable to discover this vulnerability.
See log below...

Here is the source code of the test application:
<?php
$file = $_GET['file'];
if(isset($file))
{
    include("pages/$file");
}
else
{
    include("index.php");
}
?>

Now, I had success with older Fimap versions, but like all pentesters prefer to 
keep my software up to date. It seems this version is not correctly fuzzing the 
parameters. maybe a bug somewhere in the SVN release? From what I am seeing it 
is not fuzzing GET parameters at all.

UPDATE: With blind mode flag it actually DOES work, however older versions of 
fimap did not need this flag set. I will just make sure to be using the Blind 
Mode from now on, though I hope the example gives you some ideas :)

The "cd" and "ls" commands both cause crashes. I had luck using ls -al instead 
of ls, but even cd .. instead of cd ../ cause crash. No idea why...

The "id" command seems to dump a log of the /var/log/auth.log file instead of 
executing commands also. Very odd bug :P

Pentestmonkeys reverse shell also seems to cause bugs, will continue the bug 
hunt though!

Hi the.infodox,

Sorry for my insane late response. University just started and I actually going 
now to school to finish the shit :)

But back to topic.
As you already discovered, fimap checks by default only for visible bugs.
That means that the PHP (or whatever) error message has to be visible.
I called it "sniper" in fimap. So if you read something about "Sniper failed" 
you know that fimap failed to identify a bug because the error pattern was not 
found.

You also already found out that you can enable blind mode. If you enabled 
blindmode fimap still first tries to "snipe" the site. Since this is really 
cheap there is no reason not to try it. When sniping failed, the pathes will be 
bruteforced blindly and fimap hopes to find content of the injected file.

This mode however is really verbose and obvious in the logfiles. But needed if 
errors are disabled like in your case.

As for the other bugs you posted, I will check them out these days if I have 
time.
Should be easily fixed.

Thank you very much for taking your time and giving such a great feedback!
-imax.

No worries about delayed replies, I myself have exams in the Uni now.

I figure that most of the post-shell inject bugs are due to the nature of the 
exploit method - auth log injection - which is probably not the most reliable 
of methods compared to say, error log.

A suggestion though would to be once you "inject" the shell via logfile, to 
have an option to upload a more permenant shell - for example the Weevely 
shell. I am currently trying to write such a plugin, and now have it getting as 
far as almost-running before it crashes :)

Thats using the following plugin (which, BTW, you should add to the trusted 
list!)
http://code.google.com/p/ghosthunter/source/browse/#svn%2Ftrunk%2Ffimap%2Fplugin
s%2Freversehttp

Now I saw the same error whenever I tried using the uploadfile thing, so I 
believe it is due to a bug in "item". Either that or we are using the 
uploadfile thing wrong. Not sure which.

Will keep submitting bug reports anyway :)

Hi the.infodox!

I just found and fixed the bug with the missing "item" variable.
I forgot to rename the "item" variable to "working_shell" during my 
refactorings.
Epic fail. At least this bug should be solved now and you should be able to use
most of the stuff.

If you have some time please verify that and let me know :)

Cheers and sorry for the stupid bug,
-imax.

The bug is fixed :D All works fine, however I now know auth.log is NOT a good 
place to inject also - try putting in the "pwd" command, etc, into authlog and 
it goes insane :P

BTW, I wrote a plugin last night, still in "beta" kind of as I need to fix a 
few small bugs:
http://insecurety.net/Downloads/weevils.tar.gz

It uploads a Weevely backdoor onto the victim webserver giving a "Persistent" 
password protected shell you can use :)

Hi the.infodox!

Glad the bug is fixed :) Thanks for letting me know about the bug.
I didn't even noticed it. What a shame.

I will make these days some test with the auth.log and check if I find the 
reason for the troubles with it.

If your plugin reaches final or you think it's stable enough let me know and I 
will add it to the trusted plugins!
Will test the beta tonight and see how it is :)

Cheers buddy for your time,
-imax.

I am trying to work out why auth.log blows up so massively but may take some 
time. Will eventually figure it out!

BTW I am actively redeveloping parts of the plugin:
svn checkout 
http://insecurety-research.googlecode.com/svn/trunk/fimap/plugins/weevils/ 
weevils/

Thats where this plugin will be updated until it is 100% stable and I am 
satisfied with it and can move on to more exploit-mode plugins :D

Next up maybe a reverse shell or something...
