For what purpose? Is there a new exploit?

I am not sure but I saw people were talking about some new (at least for me) encrypted union attacks or something.

There's a flurry of discussion about it at nukecops but I've yet to see the exploit that it purports to fix. Their 'fix' is breaking more things than it is fixing so if there is an exploit and someone would send it along, I will be happy to look into it.

There is one MySQL exploit that can be used to 'mask' the union attack. MySQL and a few other rdbms's allow a comment /* */ to be placed in the Query as a hint to MySQL to override it's determined course. In other words, if MySQL would determine to NOT use an index, for whatever reason, you can give it a 'hint' by placing certain code in the query in /* */. Well, the crackers out there have picked up on this and are exploiting it. Here is a proposed fix for my hack alert code in mainfile.php

Code:

$checkurl = preg_replace("#(/\*.*\*/)#", "", $_SERVER["QUERY_STRING"]); //Courtesy of http://www.esnider.net


// Raven http://ravenphpscripts.com


if (stristr($checkurl,'%20union%20')) {


   $loc = $_SERVER['QUERY_STRING'];


   header("Location: hackattempt.php?$loc");


   die();


}

I am testing it and would like you all to test it too. Once we determine it works I will modify the download. Let me know.

Hm,...

this filter worked for "NukeHackerTrap" v1.2 available at http://www.warp-speed.de :
[/CODE]
if (stristr($sRQ,'/*')) return $this->detect();
[/CODE]

I'll put it in mainfile and let you know how it works. Your original hackalert is great and I wouldn't deign to use the NC plagiarization.

Um, where in mainfile does it go? There doesn't seem a $checkurl in mainfile.

Place the line right after the file credits

Ok. Just got a bunch of hack attempt alerts from 62.254.64.8, Amsterdam natch. Why don't those little Dutch boys and girls stick their fingers in dykes instead of hacking...? Sad

Seems to catch anything I've thrown at it so far. Just a few variations on the standard %20UNION%20 and %20UN/*%20%20%20%20*/ION%20
So on and so on.

I think it works, but i had delete the last fix from sting!

Code:

$checkmyurl = preg_replace("#(/\*.*\*/)#", "", $_SERVER["QUERY_STRING"]); //Courtesy of http://www.esnider.net 


// Raven http://ravenphpscripts.com 


if (stristr($checkmyurl,'%20union%20')) { 


   $loc = $_SERVER['QUERY_STRING']; 


   header("Location: hackattempt.php?$loc"); 


   die(); 


}

$checkmyurl doesn't match if (stristr($checkurl

Corrected this observation in my past post , thanks Cool

I have just added to my site and will let you know if there are any problems, I also had to rename $checkurl tho Smile

Posted: Tue Apr 27, 2004 3:14 pm

Yeh Think I'd go for a new name for the variable
Somthing like $union_tap oh wait thats another Paul Laudanski (aka Zhen-Xjell). TM name er let me uhm see here...
How about $no_unions or $union_crap? See the AUP for further details Rolling Eyes

Have you read the latest announcement over there and some feedback? This could get lively! Hey! I forgot to copyright my code! Doggone it - now it's too late. Oh, that's right. I can wait for a more opportune time and then attack one of you for using it. How silly of me! /me slaps me, or is that YOU ARE SLAPPED BY ME? Bad, bad, bad ....

So far all I've kept up on is the posts at the .org those virtual slaps are so painful. I bet the script kiddies cry every time they get one. I know the union folks are gonna get tired of it in a hurry. Might even go out on strike over the treatment. Wink

Out of curiosity I tested Paul's Union Tap beta3 and needless to say, it should be called Union Crap. It stopped only the original exploit.

Now the Raven_Slap Idea

script stopped everything.

I must say.. I am once again impressed with your hackalert script Raven.

I tested out your script using Janek's exploit and it stopped it dead in its tracks.

Question for Chatserv... I also use $checkurl in admin.php. I added the new hackalert as is posted above.. it worked.

Do I need to change it? Embarassed

Posted: Tue Apr 27, 2004 7:28 pm

I only changed it to avoid conflicts with the previous one since mainfile.php gets included by all other files chances are eventually both url checkers might clash.

At the risk of alienating someone (not intentional), whats a noob to do. Does this script provide the same type of protection as the so called Fortress (nc) or the Protector (mister)? I installed the protector prior to finding this site. And I have gleaned and concluded that chatserv's hackalert may provide better protection? From a consumer's standpoint, it's getting difficult to know which path to follow, so please don't take offense at this question. I just would like to know if anyone has compared the three approaches to security.
