Exploitation of this vulnerability is achieved by sending a specially crafted request, granting the attacker access to the ClassLoader. The issue arises from an oversight in the data-binding logic used both during object creation and manual binding through bindData. The problem has been corrected in releases 3.3.15, 4.1.1, 5.1.9, and 5.2.1.    <\/p>\n<p>Dodatno se mo\u017ee spomenuti ranjivost u Ruby modulu tzinfo, koja omogu\u0107ava u\u010ditavanje sadr\u017eaja bilo koje datoteke, ovisno o pravima pristupa napadnute aplikacije. Ranjivost je povezana s nedostatkom adekvatne provjere upotrebe posebnih znakova u imenu vremenske zone koja se navodi u metodi TZInfo::Timezone.get. Problem se odnosi na aplikacije koje proslje\u0111uju nepouzdane vanjske podatke u TZInfo::Timezone.get. Na primjer, za \u010ditanje datoteke \/tmp\/payload mo\u017ee se navesti vrijednost poput 'foo\n\/..\/..\/\/tmp\/payload'.<br \/>\n<br \/>Izvor: <a content=\"nofollow\" rel=\"nofollow\"
