Nel plugin WordPress Ninja Forms, con oltre un milione di installazioni attive, \u00e8 stata individuata una vulnerabilit\u00e0 critica (CVE non ancora assegnato) che consente a un visitatore esterno di ottenere il controllo totale sul sito. Il problema \u00e8 stato risolto nelle versioni 3.0.34.2, 3.1.10, 3.2.28, 3.3.21.4, 3.4.34.2, 3.5.8.4 e 3.6.11. Si segnala che la vulnerabilit\u00e0 \u00e8 gi\u00e0 utilizzata per compiere attacchi e, per bloccare tempestivamente il problema, gli sviluppatori della piattaforma WordPress hanno avviato un\u2019installazione automatica forzata dell\u2019aggiornamento sui siti degli utenti. <\/p>\n

La vulnerabilit\u00e0 \u00e8 causata da un errore nell\u2019implementazione della funzionalit\u00e0 Merge Tags, che consente a utenti non autenticati di richiamare alcuni metodi statici da diverse classi di Ninja Forms (per verificare il richiamo dei metodi nei dati passati tramite Merge Tags, veniva invocata la funzione is_callable()). Era disponibile anche la chiamata a un metodo che esegue la deserializzazione del contenuto inviato dall'utente. Attraverso l'invio di dati serializzati appositamente formattati, l'attaccante poteva sostituire i propri oggetti e riuscire a eseguire codice PHP su server<\/a> o eliminare file arbitrari nella directory dei dati del sito.
