ID CVE: CVE-2022-31231
Gravità: Medio
Chi deve eseguire questa procedura?
Dell richiede che questa procedura di upgrade di xDoctor e installazione della patch venga eseguita dai clienti. È il metodo più rapido e sicuro in quanto evita l'esposizione prolungata a questa vulnerabilità. Tutti i passaggi sono descritti in dettaglio in questo articolo della Knowledge Base. Al link indicato qui sotto è disponibile anche un video di istruzioni che può essere seguito insieme a questo articolo della Knowledge Base.
Effetti della procedura:
È possibile che durante il riavvio dei servizi dataheadsvc si verifichino timeout di I/O nodo per nodo. Le applicazioni devono accedere al cluster tramite un servizio di bilanciamento del carico e devono essere in grado di gestire il timeout di I/O. Quando si esegue questa procedura, si consiglia di tenere in considerazione una finestra di manutenzione.
Eccezione di bucket solo in CAS:
Se tutti i bucket in un sistema sono esclusivamente nel CAS evidenziato di seguito, non è interessato da questa vulnerabilità della sicurezza. Pertanto, non è necessario applicare la patch e questo articolo della KB non deve essere seguito.
Comando: svc_bucket list
Esempio:

Tempo impiegato per l'attività (approssimativo):
Un ritardo di 60 secondi è impostato per impostazione predefinita per nodo tra i riavvii del servizio. Il numero di nodi in un Virtual Data Center (VDC) moltiplicato per 60 secondi + 30 minuti per la preparazione, la stabilizzazione del servizio e i controlli successivi necessari.
Esempi:
Un sistema VDC a 48 nodi può richiedere circa 80 minuti:
60 secondi X 48 (numero di nodi VDC) + 30 minuti (preparazione) = 80 minuti circa
Un sistema VDC a 8 nodi può richiedere circa 40 minuti:
60 secondi X 8 (numero di nodi VDC) + 30 minuti (preparazione) = 40 minuti circa
Domande frequenti:
D. La patch è parte integrante della release di xDoctor?
R. Lo script di installazione della patch è parte integrante della versione 4.8-84 di xDoctor e delle versioni successive. Le istruzioni per il download di xDoctor e l'installazione della patch sono contenute nella procedura di risoluzione.
D. È possibile aggiornare più VDC in parallelo?
R: No, solo una patch VDC alla volta.
D. Se si aggiorna un ECS dopo l'esecuzione di questa procedura, è necessario eseguire nuovamente la procedura dopo l'upgrade?
R. No, se si esegue l'upgrade a una versione del codice specificata in DSA-2022-153 con la correzione permanente. Sì, se si esegue l'upgrade a una versione del codice non specificata nello stesso DSA.
D. La patch deve essere riapplicata in un sistema in cui è stata precedentemente installata dopo la sostituzione, la ricreazione dell'immagine o l'espansione di un nodo?
R: No, se il VDC si trova nella versione del codice specificata in DSA-2022-153 con la correzione permanente. Sì, se si esegue una di queste azioni per un VDC che esegue una versione del codice non specificata nello stesso DSA. Se in queste situazioni è richiesta una patch, il tecnico Dell in questione contatterà l'utente per informarlo che è richiesto l'aggiornamento.
D. E se si utilizzano solo utenti legacy e non IAM?
R. I clienti devono applicare la patch indipendentemente dal fatto che utilizzino solo utenti legacy e non IAM.
D. Quale utente deve essere connesso per eseguire tutti i comandi descritti in questo articolo della KB?
R: admin
D: È necessario eseguire svc_patch su tutti i rack o con un file MACHINES specializzato quando un VDC contiene più rack?
R. No, viene rilevato automaticamente se sono presenti più rack e la patch viene applicata a tutti i nodi su tutti i rack del VDC.
D. La versione di destinazione di xDoctor non è più 4.8-84.0. Per quale motivo?
R. Nuove versioni di xDoctor vengono rilasciate di frequente, pertanto è consigliabile eseguire sempre l'upgrade alla versione più recente. Se tuttavia in precedenza è stata eseguita la correzione utilizzando la versione 4.8-84.0, il sistema è completamente protetto dalla vulnerabilità e non è necessario eseguirla nuovamente.
Riepilogo della risoluzione:
Aggiornare il software ECS xDoctor alla versione più recente disponibile.
