vb.org Archive - View Single Post - what is XSS and how can they affect a board with HTML turned on?

I think bbcode has it's limits. Back when I was changing up my bbcode more often than I am now, if I remember right, bbcode can't do 2 options only one. Personally I kinda thought bbcode was limited. I have wav files enabled for posting, flash files. People can post images stating both the height and width the image. I think with bbcode, you can't tell it what you want the height and the width to be. You can put an option when you are creating the bbcode, but then that option would have to be both the width and height. That is if I remember right.

I do remember one reason why I need html enabled. The smilies that I have above the text field where people type their images are clickable. I believe it's using one of Fireflys hacks. to insert the smilie into the users post it adds the image using a line like this:

Code:

<img src=images/icons/icon180.gif>

I might be able to dig up the hack with the instructions and maybe somebody could look at it for me and see if they could get the same hack to work without having to have html enabled for the board to recognize the smilies that are inserted into posts?

I think that was the main reason why I add html turned on.

I do however have the following commands in my censorship area:

Code:

<style </style <iframe </iframe <link </link <basefont </basefont <base </base <th </th <tfoot </tfoot <tbody </tbody <thead </thead <body </body <meta </meta <script </script <html </html <plaintext </plaintext <xmp </xmp <object <noframes <noembed <noscript <nojava onload onMouseover <fieldset :absolute style="position "position absolute; <caption

Those alone seem to keep out the nastier ones I have found some of my members using. With all those censored, I believe I have very little to no holes with the enabled html, however I know that there are probably some that I have missed, so if somebody is willing to help me get that hack that I mentioned above to get it to work without html, I would be willing to switch.
