Hey, Seth –
Well, what do you know – I did some experimenting using Google Toolbar’s Autofill, and your guess was spot-on! I was able to duplicate the exact error that the user had. You definitely win a cigar here. J I guess the moral of this story is: don’t rely on the MAXLENGTH attribute to restrict the lengths of your data anymore. Using drop-down lists would help in some cases but not all. Sigh! n Angeli From: [email protected] [mailto:[email protected]] On Behalf Of Seth Bienek Sent: Tuesday, April 14, 2009 7:10 PM To: [email protected] Cc: <[email protected]> Subject: [houcfug] Re: HTML puzzle Just had a thought: if a person were using a browser plugin that remembers their info and plugs it into forms for them (google toolbar does this for example), that app would likely use the DOM to set the value of the form field, which might side-step the browser's function of limiting input based on key strokes..? Just a theory, but I'll bet if you contact the user they would tell you they use a form helper. :) Take Care, Seth On Apr 14, 2009, at 6:34 PM, "Angeli Wahlstedt" <[email protected]> wrote: Sure, here it is (the code trimmed for brevity)…as you can see, it’s pretty barebones.

The original page was a data entry screen for a private auction, and it takes in your name, address, contact info and things like that, and the form data that showed up in the email looks completely legitimate – a residential address of some guy in Colorado. No obvious made-up data that I can see. If it’s a spam-bot or the like, someone is certainly going to a lot of trouble to make it look legitimate. J That data entry screen hadn’t been changed for several years, so it rules out the cached page theory. Maybe some weird browser bug, who knows? Anyway, I’ll just chalk it up as a fluke and not worry about it unless it comes up again. The action page already has CFQUERYPARAM’s and other safety guards in place, anyway. n Angeli From: [email protected] [mailto:[email protected]] On Behalf Of Seth Bienek Sent: Tuesday, April 14, 2009 4:58 PM To: [email protected] Cc: [email protected] Subject: [houcfug] Re: HTML puzzle Smells like a spam bot to me. They forge user agent strings, and will guess at field values to get their form submitted. If you don't include the form scope in your error emails, you should consider doing so, as it will give you more insight, no matter what the issue turns out to be.

Yeah you’re right that looks like IE7 on Vista unless it’s a forged user-agent. I would say the user either had a cached version of the page that didn’t have the size/maxlength attributes or a bug in the browser or something else off the wall. It could be a hack attempt, but there’s more interesting things to try than “Colorado”.

I just got an automatically generated email from one of the sites I work on, containing a Cold Fusion error. The error was caused by a CFQUERYPARAM tag trying to save a too-long string to a database. I went to the original page, thinking that an INPUT tag is missing a MAXLENGTH attribute somewhere. But it turns out that the INPUT tag indeed has its both SIZE and MAXLENGTH in place. It works as it should when I tested it in IE 7.0 and Foxfire. So, the question is, how did this too-long string (which was the value “Colorado”) get past a 2-character text box? One possibility would be a custom-written form outside the web server, but the HTTP_REFERRER variable pointed at the original page on the web server. If it helps anything, the user agent was “Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 6.0; GTB5; SLCC1;.NET CLR 2.0.50727; .NET CLR 3.0.04506; MS-RTC LM 8” which looks like IE 7.0, if I’m reading it correctly.
