\u00cen pluginul WordPress Ninja Forms, care are peste un milion de instal\u0103ri active, a fost descoperit\u0103 o vulnerabilitate critic\u0103 (CVE deocamdat\u0103 nesolicitat\u0103), care permite unui vizitator neautorizat s\u0103 ob\u021bin\u0103 control total asupra site-ului. Problema a fost remediat\u0103 \u00een versiunile 3.0.34.2, 3.1.10, 3.2.28, 3.3.21.4, 3.4.34.2, 3.5.8.4 \u0219i 3.6.11. Se observ\u0103 c\u0103 vulnerabilitatea este deja utilizat\u0103 pentru atacuri, iar pentru a bloca urgent problema, dezvoltatorii platformei WordPress au ini\u021biat instalarea automat\u0103 for\u021bat\u0103 a actualiz\u0103rii pe site-urile utilizatorilor. <\/p>\n

Vulnerabilitatea este cauzat\u0103 de o eroare \u00een implementarea func\u021bionalit\u0103\u021bii Merge Tags, care permite utilizatorilor neautentifica\u021bi s\u0103 invoce anumite metode statice din diverse clase Ninja Forms (pentru a verifica invocarea metodelor \u00een datele transmise prin Merge Tags se apela func\u021bia is_callable()). De asemenea, a fost disponibil\u0103 invocarea unei metode care efectueaz\u0103 deserializarea con\u021binutului transmis de utilizator. Prin transmiterea unor date serializate special concepute, atacatorul putea efectua substituirea obiectelor sale \u0219i putea executa cod PHP pe server<\/a> sau \u0219terge fi\u0219iere arbitrare din directorul cu datele site-ului.
