I Cisco Small Business-switches er der identificeret 4 s\u00e5rbarheder, der giver en fjernangriber mulighed for at f\u00e5 fuld adgang til enheden med root-rettigheder uden autentificering. For at udnytte problemerne skal angriberen kunne sende anmodninger til netv\u00e6rksporten, der muligg\u00f8r webgr\u00e6nsefladens funktion. S\u00e5rbarhederne er klassificeret med en kritisk faregrad (9,8 ud af 10). Der rapporteres om en fungerende prototype af et exploit. <\/p>\n

De identificerede s\u00e5rbarheder (CVE-2023-20159, CVE-2023-20160, CVE-2023-20161, CVE-2023-20189) skyldes fejl i h\u00e5ndteringen af hukommelsen i forskellige behandlere, der er tilg\u00e6ngelige f\u00f8r autentificering. S\u00e5rbarhederne f\u00f8rer til en buffer-overl\u00f8b ved behandling af specielt udformede eksterne data. Derudover er der fire mindre farlige s\u00e5rbarheder (CVE-2023-20024, CVE-2023-20156, CVE-2023-20157, CVE-2023-20158) i Cisco Small Business-serien, der giver mulighed for at initiere en denial-of-service fjernbetjent, samt \u00e9n s\u00e5rbarhed (CVE-2023-20162), der giver mulighed for at f\u00e5 oplysninger om enhedens konfiguration uden autentificering. <\/p>\n

S\u00e5rbarhederne p\u00e5virker serierne Smart Switch 250, 350, 350X, 550X, Business 250 og Business 350 samt Small Business 200, 300 og 500 serierne. I serierne 220 og Business 220 er s\u00e5rbarheden ikke til stede. Problemerne er l\u00f8st i firmware-opdateringerne 2.5.9.16 og 3.3.0.16. Firmware-opdateringer for serierne Small Business 200, 300 og 500 vil ikke blive udarbejdet, da livscyklussen for disse modeller allerede er afsluttet.
