I ricercatori di sicurezza di Armis hanno rivelato<\/a><\/noindex> informazioni su 11 vulnerabilit\u00e0<\/a><\/noindex> (PDF<\/a><\/noindex>) nel stack TCP\/IP IPnet, utilizzato nel sistema operativo VxWorks. I problemi hanno ricevuto il nome in codice \u00abURGENT\/11\u00bb. Le vulnerabilit\u00e0 possono essere sfruttate da remoto inviando pacchetti di rete appositamente formati, incluso in alcuni casi la possibilit\u00e0 di attacco attraverso firewall e NAT (ad esempio, se l'attaccante controlla un server DNS a cui si rivolge un dispositivo vulnerabile situato in una rete interna).<\/p>\n

\"11<\/a><\/noindex><\/center><\/p>\n

Sei problemi possono consentire l'esecuzione di codice da parte di un attaccante durante l'elaborazione di opzioni IP o TCP non corrette in un pacchetto, cos\u00ec come durante l'analisi dei pacchetti DHCP. Cinque problemi sono meno gravi e possono portare a fughe di informazioni o a attacchi DoS. La divulgazione delle vulnerabilit\u00e0 \u00e8 stata coordinata con l'azienda Wind River - nel recente rilascio della scorsa settimana di VxWorks 7 SR0620 i problemi sono gi\u00e0 stati risolti.<\/p>\n

Poich\u00e9 ogni vulnerabilit\u00e0 colpisce diverse parti dello stack di rete, i problemi possono essere specifici per determinate versioni, ma si afferma che in ogni versione di VxWorks a partire dalla 6.5 si manifesti almeno una vulnerabilit\u00e0 che consente l'esecuzione remota di codice. Per ogni variante di VxWorks \u00e8 necessario sviluppare un exploit separato. Secondo la compagnia Armis, il problema interessa circa 200 milioni di dispositivi, tra cui attrezzature industriali e mediche, router, telefoni VOIP, firewall, stampanti e vari dispositivi IoT. <\/p>\n

Wind River ritiene<\/a><\/noindex>, affermando che questa cifra \u00e8 gonfiata e che il problema riguarda solo un numero relativamente ridotto di dispositivi non critici, che di solito sono limitati a una rete aziendale interna. Lo stack di rete IPnet era fornito solo in alcune edizioni di VxWorks, comprese le versioni la cui supporto \u00e8 gi\u00e0 cessato (fino alla 6.5). Nei dispositivi basati sulle piattaforme VxWorks 653 e VxWorks Cert Edition, utilizzate in settori critici (robot industriali, elettronica automobilistica e aeronautica), i problemi non si manifestano.<\/p>\n

I rappresentanti di Armis ritengono che, a causa della complessit\u00e0 degli aggiornamenti dei dispositivi vulnerabili, non si possa escludere la comparsa di worm che colpiscono le reti locali e attaccano in massa le categorie di dispositivi vulnerabili pi\u00f9 popolari. Ad esempio, alcuni dispositivi, come le attrezzature medicali e industriali, richiedono una ri-certificazione e un lungo periodo di test quando si aggiornano i firmware, il che complica il processo di aggiornamento.<\/p>\n

Wind River believes<\/a><\/noindex>, in questi casi il rischio di compromissione pu\u00f2 essere ridotto attivando i gi\u00e0 esistenti strumenti di sicurezza integrati, come stack non eseguibili, protezione contro il buffer overflow, limitazione delle chiamate di sistema e isolamento dei processi. La protezione pu\u00f2 essere garantita anche tramite l'aggiunta di firme di attacco bloccanti nei firewall e nei sistemi di prevenzione delle intrusioni, oltre a limitare l'accesso di rete al dispositivo solo tramite il perimetro di sicurezza interno.<\/p>\n
