Oggi il nostro team di sicurezza ha ricevuto conferma di una vulnerabilit\u00e0 critica in Linux che interessa tutti i kernel a partire dalla 5.8 (CVE-2022-0847<\/a>), soprannominata The Dirty Pipe<\/a>. La vulnerabilit\u00e0 pone un rischio per la sicurezza estremamente elevato, consentendo agli aggressori di sovrascrivere i file chiave del sito e di ottenere l’accesso completo ai server. Inutile dire che si tratta di un’enorme minaccia alla sicurezza con una portata molto ampia che consente l’accesso senza privilegi ai processi di root e ai file di configurazione.<\/p>\n\n\n\n

Il nostro team di sicurezza ha iniziato a lavorarci subito dopo i report iniziali. Anche se il Kernel Linux \u00e8 un software di terze parti, in SiteGround abbiamo agito proattivamente con il nostro team di sicurezza dedicato, invece di aspettare una versione ufficiale della patch. I nostri Kernel Specialist hanno sviluppato una mitigazione personalizzata che \u00e8 stata ampiamente testata. Una volta che siamo stati certi che nessun’altra funzionalit\u00e0 fosse interessata, la correzione \u00e8 stata implementata su tutti i nostri sistemi e server, poche ore dopo la scoperta della vulnerabilit\u00e0.<\/p>\n\n\n\n

Siamo stati tra i primissimi, se non il primo hosting, a scrivere e distribuire con successo una patch contro questa minaccia alla sicurezza ad alto rischio. Al momento, nessun server SiteGround \u00e8 interessato da questa vulnerabilit\u00e0 e non si sono verificati tempi di inattivit\u00e0 nell’intero processo. I nostri clienti sono completamente protetti e non hanno bisogno di apportare modifiche!<\/p>\n","protected":false},"excerpt":{"rendered":"Oggi il nostro team di sicurezza ha ricevuto conferma di una vulnerabilit\u00e0 critica in Linux che interessa tutti i kernel a partire dalla 5.8 (CVE-2022-0847), soprannominata The Dirty Pipe.
