Is this sequence "ALTER …" an attack of some kind?
The seqence below is a form submission on a personal site of mine and seems to be crashing the browser.
It crashes the browser of my site's backend where I approve submissions, and it crashes gmail when displaying the email notification of the submission. At least I think it's this submission...
I'm wondering if it's some kind of attack that takes advantage of some memory vulnerability or something... like a memory overflow. I don't know... I'm not an expert.
The sequence doesn't look malicious, but it (I think it) has crashed my mail and browser several times today.
Took me a minute to track it down because it was just gmail dying (javascript busy / timeout). I traced it back to when that message was loaded on screen.
I then hunted it down in my app. I tried to look online but didn't come up with much.
Any help appreciated, and especially how to guard against this. I'm a web developer, but this isn't an attack I recognize. It seems to have an effect even when escaped.
Thanks
