The painful part about the blink tag is when you print the page. You have to time it just right so that it prints when the text is on rather than off. I have to print it several times sometimes before I get a good one.

Chiang Mai. 3 weeks ago. Mrs. dreamsign and I are sitting across from a single diner, who starts talking to her waiter about cilantro, so, you know, we figure it was the please-god-no-freaking-cilantro conversation and thought nothing more of it. Till her bowl of cilantro arrived and she started grazing on it.

*shudder*

Not breakfast, though.

The negative reinforcement for non-clever use of the blink tag is sufficiantly severe that I really, really don't think we need to worry about its over-use.

Seriously, you think Comic Sans has it rough? Somebody just did a callout on meTa about a single not very annoying use of blink.

I used to mentor a guy who was always trying to get me to use blink. Sometimes I even thought he was serious about it.

It takes practice, but if you catch the rhythm and blink synchronously, you won't notice the blink. Depending on your timing, you then have two options--to read the blinking comments as if they were not blinking, or avoid them altogether.

It's not stripped because it's 'malformed.' You run the one attribute right up against the closing ' of the previous attribute, which is poor form but apparently parsable.

My the colors are pretty. Can we have colors all the time please mathowie? huh? can we? huh?
posted by Cranberry at 4:57 PM on September 14, 2007


The problem is you can't allow just colors, if you allow inline styles then you open up an entire world of exploits as this thread has shown.

This is also a very good illustration of why BBcode came to exist. If you use tags like [b] that aren't actual HTML then you can ruthlessly filter all actual HTML (such as < and >) which makes this kind of attack much easier to deal with.

Rhomboid has a good point.
Can you imagine the anarchy if we could all post using the colours and fonts that we want, Cranberry? It can't happen. Metafilter depends quite strongly on uniformity and flatness for that warm, we-are-all-the-same design and sense of community. I guess.

Maybe we should have a free-for-all thread every few months to get it all out at once. This feels so cathartic.

posted by yhbc at 6:41 PM on September 14, 2007


explanation: My friend Leonard Lin (randomfoo, upcoming, yahoo hack day) wrote some tag balancer code in late 2001, so that unclosed bold tags would get closing bold tags added to them. Then he wrote some code to exlude bad tags like embed and iframe, and went ahead and wrote code to filter out attributes like javascript: and style, stuff that can be used to mess up a site even back then.

Years have gone by and we've done a few tweaks to the code, but the code originally as written would look for new comments with and <text> in them. It would strip out the text in between (text, in this case) and call that a tag. If it saw a space following it, it considered anything else an attribute (like a href=yahoo.com where href is an attribute of a, the anchor element). It was looking for spaces after any remaining text to delimit another attribute.

So the gist of the problem was that today gary figured out that you could immediately follow allowed attributes with disallowed ones. So the text: title='style='color:red;' was being interpreted by the only attribute, and it was considered all part of the allowable "title" attribute. The real problem is you could follow with any attribute you wanted, including every crazy javascript exploit known to man, which is why this wasn't just about comic sans fonts, but really about the entire site's security for member accounts.

Jason Levine (delfuego) cleaned up the attribute filters so that the missing space didn't consider it all part of one attribute and solved the hack that was used today to do these sorts of display things.

posted by delfuego at 8:12 PM on September 14, 2007


Part of what was kicking most of your asses when you were trying to pull the hack off based on observed source:

Mefi eats (or ate? I'll have to test this, now) pairs of ' characters that go through the stripper function, leaving one behind. So if you had ' twice in a row, you'd hit post and get just one ' on the other side.

So this:

title=''style'comic sans lol'

was failing for you because the ass end of your work came out as

title='style'comic sans lol'

or something similarly non-exploitatively broken. You'd just end up with the bare function of your root tag, be it bold or italic or blink or whatever.

Two workarounds: use actual text in the title:

title='dongs rofl'style='lkjlkjsldfjks'

Or double up your quote marks, so the pairs that get eaten down to single leave you with two left over:

title=''''style='font:assclown'

I figured the quote-halving thing out a while back when it kept fucking up some ascii art I was working on.

/looks like delfuego's fix is doing a fine job of stripping the forbidden attributes and recognizing the allowed attributes, but then it's tacking those allowed attributes onto the front of the comment and hiding them somehow.

Let's be very clear -- I'm an idiot. I made a change this morning to the code to deal with a remaining hole that someone emailed about overnight, and I left one line of debug code in; that debug code is what was leaving those ["whatever"] comments all over the place. *sheepish apology* It's fixed now.

And just to clear one other thing up: yes, we all know that the "exploits" still work in the Live Preview box, but it doesn't matter one whit -- that box only exists on your machine, in your browser, and as soon as you submit your comment the malicious bits get stripped out. It's doable to prevent even the exploits in the Live Preview box, but it'll take a change to how Matt provides the previews; I've offered to make the change, and it's up to him.

Did link tags with spaces before/after the equals sign work before? Looking at the original version of the code, they shouldn't have -- and I think that might be correct, since putting a space before/after the equals might violate the (X)HTML spec.

That being said, I just fixed the filter script so it handles that case.

delfuego, I think it used to gracefully strip spaces from attr="sdsd" pairs that had a space on one or both sides of the equals sign. Or at least some variants of those. Which is pretty weird—I don't think it's valid html, at least, and I'm surprised that anybody does that, though that's probably just because I don't.
