Re[6]: [PHP] Re: Security, Late Nights and Overall Paranoia

Hello Greg, Monday, July 11, 2005, 5:06:51 PM, you wrote: GD> I wouldn't know, <span> isn't one of the tags I allow. If you stick to the plain vanilla HTML tags such as i, b, u, etc then BBCode is pointless - I agreed on this with you several posts ago. I don't however use it just for that, I use it to let thousands of kids add a little sparkle to their messages/profiles with colours, images, etc -- without them having to have good CSS/HTML knowledge (most of them could handle a font tag, but that'd break my XHTML Trans). This is the point I argued all along to which I get "it's not really a security benefit" (no, it's a user benefit) and it's a "misuse of cpu cycles". For people I hold in such high regard, I'm ashamed at the lot of you :) GD> I don't bother with perfect tag validation, and I doubt the phpbb GD> bbcode people do either since they average about 2-3 exploits a GD> month on Bugtraq. Not that I'd let an install of phpBB anywhere near a site I run, they didn't invent BBCode, and in all fairness to those guys the majority of their exploits are elsewhere.
