Nei commutatori Cisco della serie Small Business sono state individuate 4 vulnerabilit\u00e0 che consentono a un attaccante remoto di ottenere accesso completo al dispositivo con privilegi di root senza necessit\u00e0 di autenticazione. Per sfruttare queste vulnerabilit\u00e0, l'attaccante deve avere la possibilit\u00e0 di inviare richieste sulla porta di rete che gestisce l'interfaccia web. Alle problematiche \u00e8 stato assegnato un livello critico di pericolo (9.8 su 10). Si segnala la presenza di un prototipo di exploit funzionante. <\/p>\n

Le vulnerabilit\u00e0 individuate (CVE-2023-20159, CVE-2023-20160, CVE-2023-20161, CVE-2023-20189) sono causate da errori nella gestione della memoria in diversi handler disponibili prima dell'autenticazione. Le vulnerabilit\u00e0 portano a un overflow del buffer durante l'elaborazione di dati esterni appositamente formattati. Inoltre, nella serie Cisco Small Business sono state trovate quattro vulnerabilit\u00e0 meno gravi (CVE-2023-20024, CVE-2023-20156, CVE-2023-20157, CVE-2023-20158) che consentono di avviare un attacco denial of service da remoto, e una vulnerabilit\u00e0 (CVE-2023-20162) che consente di ottenere informazioni sulla configurazione del dispositivo senza autenticazione. <\/p>\n

Le vulnerabilit\u00e0 interessano le serie Smart Switch 250, 350, 350X, 550X, Business 250 e Business 350, oltre alle serie Small Business 200, 300 e 500. Nei commutatori della serie 220 e Business 220 la vulnerabilit\u00e0 non si manifesta. I problemi sono stati risolti negli aggiornamenti del firmware 2.5.9.16 e 3.3.0.16. Per le serie Small Business 200, 300 e 500 non saranno rilasciati aggiornamenti del firmware, poich\u00e9 il ciclo di vita di questi modelli \u00e8 gi\u00e0 terminato.
