Omschrijving

HPE heeft meerdere beveiligingsproblemen verholpen in Brocade Fabric OS, specifiek in versies vóór 10.0.1 en in de 9.2.x en 10.0.x release lijnen.

De kwetsbaarheden omvatten onder andere authenticatieomzeiling, denial of service, informatielekken, privilege-escalatie, buffer overflows, command injection, en arbitrary code execution. Aanvallers kunnen via verschillende aanvalsvectoren, zoals speciaal vervaardigde managementverzoeken, REST API-aanroepen, web management interfaces, en configuratiebestanden, ongeautoriseerde administratieve acties uitvoeren, root-commando's lokaal of op andere fabric-leden uitvoeren, en systeemprocessen laten crashen.

Sommige kwetsbaarheden maken het mogelijk om sessiecontext te vervalsen, HTTP-headers te spoofen, en gevoelige systeem- en monitoringdata in te zien zonder juiste rechten. Daarnaast zijn er race conditions en thread-safety problemen die leiden tot onjuiste toegangscontrole en audit logging. Specifieke componenten zoals de diagnostic kernel module, IKEv2 protocol handler, WebTools interface, en REST API zijn betrokken bij deze kwetsbaarheden.

Sommige problemen vereisen geauthenticeerde toegang, terwijl andere ook door niet-geauthenticeerde, netwerknabije aanvallers kunnen worden misbruikt. De kwetsbaarheden beïnvloeden de integriteit, vertrouwelijkheid en beschikbaarheid van de fabric operating system omgeving en de onderliggende netwerk- en opslaginfrastructuur.
