CVE-id: CVE-2022-31231
Alvorlighed: Mellem
Hvem skal køre denne procedure?
Dell anmoder om, at denne procedure med opgradering af xDoctor og installation af programrettelsen udføres af kunderne. Dette er den hurtigste og sikreste metode, da den undgår langvarig eksponering for denne sårbarhed. Alle trin er beskrevet i denne vidensbase. Der er også en videoguide, som kan følges for at ledsage denne KB, som findes på nedenstående link.
Procedurens virkninger:
Forvent mulige I/O-timeouts, mens dataheadsvc-tjenester genstartes node for node. Programmer skal have adgang til klyngen via en Load Balancer og skal kunne håndtere I/O-timeout. Der anbefales et vedligeholdelsesvindue, når du udfører denne procedure.
CAS kun buckets Undtagelse:
Hvis alle buckets på et system udelukkende er CAS, der er fremhævet nedenfor, påvirkes det ikke af denne sikkerhedssårbarhed. Det er derfor ikke nødvendigt at anvende plasteret, og denne KB behøver ikke at blive fulgt.
Kommando: svc_bucket liste

Den tid, det tager for aktiviteten (cirka):
Der indstilles som standard en forsinkelse på 60 sekunder pr. node mellem tjenestens genstart. Antallet af noder i et VDC (Virtual Data Center) ganget med 60 sekunder + 30 minutter til forberedelse, servicestabilisering og efterfølgende kontrol.
Eksempler:
Et VDC-system med 48 noder kan tage ca. 80 minutter:
60 sekunder X 48 (antal VDC-noder) + 30 minutter (forberedelse) = ca. 80 minutter.
Et VDC-system med 8 noder kan tage ca. 40 minutter:
60 sekunder X 8 (antal VDC-noder) + 30 minutter (forberedelse) = ca. 40 minutter.
Ofte stillede spørgsmål (FAQ):
Sp: Er plasteret en del af xDoctor-udgivelsen?
En: Den patch installere script er en del af xDoctor release 4.8-84 og højere. Instruktioner til download af xDoctor og udførelse af patchinstallation findes i opløsningstrinnene.
Sp: Kan jeg opdatere flere VDC'er parallelt?
En: Nej, patch 1 VDC ad gangen.
Sp: Hvis jeg opgraderer ECS efter at have kørt denne procedure, kører jeg så proceduren igen efter opgraderingen?
Sv.: Nej, hvis du opgraderer til en kodeversion, der er angivet i DSA-2022-153, som har den permanente rettelse. Ja, hvis du opgraderer til en kodeversion, der ikke er angivet i samme DSA.
Sp: Skal programrettelsen anvendes igen på et system, hvor den tidligere var installeret efter en nodeudskiftning, genafbildning eller udvidelse?
En: Nej, hvis VDC har den kodeversion, der er angivet i DSA-2022-153, som har den permanente rettelse. Ja, hvis du foretager nogen af disse handlinger mod en VDC, der kører en kodeversion, som ikke er specificeret i den samme DSA. Hvis programrettelsen er påkrævet til disse scenarier, kontakter den pågældende Dell-tekniker for at få oplyst, at opdatering er påkrævet.
Sp: Hvad hvis jeg kun bruger ældre brugere og ikke bruger IAM?
En: Kunderne skal anvende programrettelsen, uanset om de kun bruger ældre brugere og ikke IAM.
Sp: Hvilken bruger skal du være logget på for at udføre alle kommandoer i denne KB?
A: admin
Q: Skal svc_patch køres på alle racks eller med en specialiseret MACHINES-fil, hvor flere racks i en VDC?
En: Nej, den registrerer automatisk, hvis der findes flere racks, og retter alle noder på alle racks på den pågældende VDC.
Sp: Jeg bemærker, at målet xDoctor frigivelse ikke længere er 4,8-84,0. Hvorfor?
A: xDoctor udgivelser forekommer ofte, så det anbefales altid at opgradere til højest udgivne version. Hvis du imidlertid tidligere har kørt rettelsen ved hjælp af 4.8-84.0, er systemet fuldt beskyttet mod sårbarheden og behøver ikke at blive kørt igen.
Løsningsoversigt:
Opgrader ECS xDoctor-softwaren til den nyeste tilgængelige version.
