Hacking Guestbooks

Guestbooks are one of the most easly and most common begginer hacks. Because Guestbooks allow users to submit their information onto the website.

So if a guestbook was to not filter html commands, then that information is submitted to the website!!! See where im going with this....

So if you were to input html into your guestbook entry, that will be uploaded to the website, thus giving you control of that page.

So, steps to take when hacking a guestbook:

see if its vunerable! You can do this by inputing tags like:

<plaintext> or <img src="javascblockedript:alert('noob')">

If you get a whole page of code (plaintext) or a message box saying "noob", then the page is vunerable.


So now you can attack the guestbook!

to make a message pop up on the screen, you inject javascblockedript into a <img> tag or a <scblockedript>, but sometimes [scblockedript] is disabled.

so a img tag would be like:
<img src="javascblockedript:alert('noob')">

or if you wanted to redirect the page, you can use another <img> tag:
<img src="javascblockedript:void(window.location=('http://www.google.com'))">
WoW, now that page redirects to your page! simpe huh!!

Be creative, any html command can work!

Happy Hacking.
