$PHP_SELF

Hi all,

 

I saw some website they wrote $PHP_SELF is not secure.

It will causing XSS to exploit your site.

 

But I don't know how XSS will bring harm to us.

Because most of the example they just inject a script alert.

But it can't change our code or anything.

It may inject a javascript. but I can't see what can it done with javascript that until it causing serious problem to our site.

 

I believe that XSS will bring major securities issues. But I just don't know how it works.

 

So back to the topic, instead of $PHP_SELF, I should use $_SERVER['PHP_SELF'] ?

 

Are there any methods to use besides this two?

thanks

$PHP_SELF and  $_SERVER['PHP_SELF'] are essentially the same.

 

Also, if a user manages to inject malicious Javascript into a database (where it will be echo'd somewhere), they can steal login cookies and whatnot.

$PHP_SELF is deprecated.
