spam vulnerability
(old news - 04:45PM Wednesday Nov 26 2003)
tags: security · spam
One of the most popular blog packages, Movabletype, comes with a utility, not even used in the default configuration, that can (and is) being hijacked by spammers trying to sell Viagra© to turkeys. If you operate a Movabletype blog, please make sure you read the front page of movabletype.org urgently.

If you get a spam email that says, in its message body, "... has sent you a link .. Title: .. Link: ...", then please refer to its FROM address. For once, it will be correct. A courtesy email to the blog owner (visit their domain) should wake them up.

What the spamers deserve.

The spamers should be tied down in a very uncomfortable position, with a little apparatus swing around their crouch, hitting it every couple of seconds. Then saw off their necks, 1mm at a time, every 2 hours, until they die.

How are they going to ever learn if you go easy on them like that? lol

How about cutting off a finger or toe every half an hour?

Re: What the spamers deserve.

Cut off one finger for each spam e-mail they send. After they have sent the first 10, guess what's next.

Nah.. only little parts of each every 15 minutes... we wouldn't want them having the honor of getting their fingers chopped off in one piece... that would not be painful enough to teach them anything. An added bonus to them not having fingers, they cant type normally, if at all.

The fix isn't very good

Reading the fix that movabletype.org have done .. well, it doesn't strike me as particularly good. So now they've limited the script to one target address and a short message body?

A spam-bot with a list of N movable type domain names could, in parallel, spam N people per second, even if everyone fixed their script per the recommendation. Ok that isn't as efficient as spamming NxM people per second (the original script allowed lists of people). But it is still possible.

It would be better if movabletype.org put a challenge response token into the loop, so you can't POST to it unless you have done a GET of the form, first, and a delay as well. Better still, remove the ability to enter a custom message (where the advert goes) entirely!

Or just remove the script and do not allow anon users to send links to any email address they like.

Me too, the fix is horrible. Basically, the fix shows that they are lazy and that they don't want to fix it the correct way.

Re: The fix isn't very good

In all fairness to Ben and Mena I don't think you can call them 'lazy' over a bad fix.. Movable Type is still a terrific tool and still free.. Hopefully they'll have a better fix soon, in the meantime, people should just remove the script altogether. There's no true need for it.

Thanks for the heads up!

Thanks for posting this. I had a problem last month where someone was spamming AOLers with Viagra ads from my address, and I couldn't figure out how it was being done. Now I know. File deleted.

Doh

Who's to blame more, the lazy programmers or the "ingenious" spammers?

Hard to call them lazy when they post their software free for public use. I don't care if it had 100 security flaws, if it's FREE, then one should not complain...

Tell that to the thousands of Internet Explorer complainers...

Seems like any mechanism which allows what is essentially an open relay is a horrible idea in this day and age, no matter what it costs.

The fact something is free doesn't automatically void the authors from being responsible for flaws in their code.

Open-source should NOT be used as a way for programmers to get around having to take responsibility for something they've created. The more it becomes such, the more crap software we're going to see in times to come.

Re: Doh

who says they are not being responsible? seems to me, they take at least as much an interest in a quick fix as any for-cash software company does. And try asking microsoft or oracle for damages when their software has a problem!

Re: Doh

In the case of the MT folks, they've been generally pretty responsible when it comes to providing patches and being up-front with users about the impact of bugs or security flaws. It's good to see that some open-source developers still believe in taking responsibility for their code.

My statement was more general than it was specific to the MT authors; the majority of my experiences with OSS authors has been "since we give you the code, you can fix the problem yourself." It's that kind-of excuse which makes me wonder how many people live in hobbit holes...

Re: Doh

really? that doesn't sound like any OSS projects I can imagine. Are you sure you are not confusing requests for features you want, which may of course be ignored, with notification of important bugs and security problems?

Re: Doh

I've spent too many years working with OSS to confuse the two. The response I speak of I've received from members of the Apache team (re: RFC931/1413 flaw which could lead to a buffer overflow and still exists today, re: zombie processes caused on many systems in 1.3.29), developers of SpamAssassin (re: spamd leaving zombie processes around on BSD systems), BIND 8.x (re: potential security hole: zone transfer tempfiles put in main root dir only when using key-based authentication, requiring the daemon to have full rwx access to /etc/namedb, rather than putting them in the appropriate zone directory from each zone directive), GNU screen (re: code checking for ~/.nethackrc despite "nethack off" being specified in .screenrc), PHP 4.x (re: returning status code of 200 regardless of what Apache says is a legitimate command; still exists today), FreeBSD sendmail updates (re: expanding etc/mail/Makefile to support sendmail's "cidrexpand" script so one can use CIDR notation in etc/mail/access; this is more of a feature, but the response was a real let-down) and numerous other mainstream applications.

I've been trying to keep a list of all the issues I've reported which go either unresponded to or illicit the standard "You have the source, fix it yourself" response, but I run into stuff too often to maintain a coherent list...

I'm just one guy with very interesting experiences with the OSS community, most of them negative. But it still warms my heart (honestly) when I see an OSS developer step in and say "Thanks for reporting this! I'll provide and commit a patch in a few minutes," or simply push out a new release.

Anyways, without getting too off track, my point is that peoples' responsibilities shouldn't be nullified whether or not the application is free or commercial.

Yeah but the last time i checked this was free and all the microsoft products i have i paid out my ass for. If im paying as much as i did for windows or office then im expecting it to be a good, quality, error free program(which windows is not!) but if something is free i will be happy if it works at all b/c i paid nothing for it and as long as my comp is not damaged or compromised, then i could care less.

Exploits

An exploit is an exploit. As long as the software is written by humans, then there are going to be exploits. Most are found before patches are released. However, it seems that all companies release patches pretty quickly.

If this was a Microsoft vulnerability, then the boo birds would be out in force in this thread. I am saying to have realistic expectations. To expect no flaws is not acceptable....unfortuniatly.
