L'attacco viene eseguito aggiungendo al documento un file 'database\/script' con il comando SCRIPT, il cui contenuto viene registrato in un nuovo file, il cui percorso pu\u00f2 essere impostato dall'attaccante.\n<li class=\"l\"> La vulnerabilit\u00e0 CVE-2012-5639 consente di caricare e aprire automaticamente risorse interne o esterne senza avvisare l'utente. Questa vulnerabilit\u00e0 \u00e8 stata scoperta in LibreOffice nel 2012, ma la segnalazione del problema \u00e8 stata chiusa come non valida. Tuttavia, \u00e8 stata corretta in LibreOffice 4.2 nel 2014, ma non \u00e8 stata notata in OpenOffice.\n<li class=\"l\"> La vulnerabilit\u00e0 CVE-2022-43680 consente potenzialmente di eseguire codice arbitrario aprendo documenti appositamente creati in una situazione di mancanza di memoria per la loro elaborazione. La vulnerabilit\u00e0 porta a un accesso alla memoria dopo che \u00e8 stata liberata (Use after free) a causa di un errore nella libreria libexpat, utilizzata per analizzare i dati nel formato XML. Il problema \u00e8 stato risolto nella libexpat 2.4.9.\n<li class=\"l\"> La vulnerabilit\u00e0 CVE-2023-47804 consente di inserire in un documento un collegamento che richiama un macro con argomenti arbitrari, permettendo l'esecuzione del proprio script quando l'utente clicca su quel collegamento o quando eventi collegati al documento si attivano automaticamente senza conferma preventiva dell'operazione. Questa vulnerabilit\u00e0 definisce un nuovo vettore di attacco per il problema CVE-2022-47502, corretto in OpenOffice 4.1.14.  <\/ul>\n<p>Fonte: <a content=\"nofollow\" rel=\"nofollow\"
