Le vulnerabilit\u00e0 sono presenti nello stack di rete del firmware utilizzato per la gestione dell'avvio di rete (PXE). Le vulnerabilit\u00e0 pi\u00f9 pericolose consentono a un attaccante non autenticato di eseguire codice remoto a livello di firmware nei sistemi che supportano l'avvio PXE tramite rete IPv6.     <\/p>\n<p>Problemi meno gravi portano a interruzioni del servizio (blocco dell'avvio), perdite di informazioni, avvelenamento della cache DNS e intercettazione di sessioni TCP. La maggior parte delle vulnerabilit\u00e0 pu\u00f2 essere sfruttata dalla rete locale, ma alcune consentono anche attacchi dalla rete esterna. Uno scenario tipico di attacco consiste nel monitorare il traffico nella rete locale e nel inviare pacchetti appositamente formattati quando viene rilevata attivit\u00e0 legata all'avvio del sistema via PXE. L'accesso a <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/it\/server\/dts-shicago\/\"   title=\"server\" data-wpil-keyword-link=\"linked\"  data-wpil-monitor-id=\"2874\">server<\/a> un server di avvio o DHCP non \u00e8 necessario.

In particolare, il modulo vulnerabile NetworkPkg con implementazione del boot PXE \u00e8 utilizzato nei firmware sviluppati da aziende come ARM, Insyde Software (Insyde H20 UEFI BIOS), American Megatrends (AMI Aptio OpenEdition), Phoenix Technologies (SecureCore), Intel, Dell e Microsoft (Project Mu).
