CVE-ID: CVE-2022-31231
allvarlighetsgrad: Medel
Vem ska köra den här proceduren?
Dell begär att denna procedur för uppgradering av xDoctor och installation av korrigeringsfilen utförs av kunder. Detta är den snabbaste och säkraste metoden eftersom den undviker långvarig exponering för denna sårbarhet. Alla steg beskrivs i den här kunskapsbasartikeln. Det finns också en videoguide som kan följas till denna KB som finns på länken nedan.
Förfarandets inverkan:
Förvänta dig möjliga I/O-tidsgränser medan dataheadsvc-tjänster startas om nod för nod. Program ska ha åtkomst till klustret via en lastbalanserare och måste kunna hantera I/O-tidsgränsen. En underhållsperiod rekommenderas när du utför den här proceduren.
Undantag för endast CAS-buckets:
Om alla buckets i ett system enbart är CAS som är markerade nedan påverkas det inte av den här säkerhetsbristen. Det är därför inte nödvändigt att applicera korrigeringsfilen och denna KB behöver inte följas.
Kommando: svc_bucket lista
Exempel:
admin@ecs-n1:~> svc_bucket list

Friday_cas region_ns RG1 Friday_cas VDC1 CAS false Disabled False
Tidsåtgång för aktiviteten (ungefär):
En fördröjning på 60 sekunder anges som standard per nod mellan omstarter av tjänsten. Antalet noder i ett virtuellt datacenter (VDC) multiplicerat med 60 sekunder + 30 minuter för förberedelse, tjänststabilisering och efterkontroller.
Exempel:
Ett VDC-system med 48 noder kan ta cirka 80 minuter:
60 sekunder X 48 (Antal VDC-noder) + 30 minuter (förberedelse) = 80 minuter ca.
Ett VDC-system med 8 noder kan ta cirka 40 minuter:
60 sekunder X 8 (Antal VDC-noder) + 30 minuter (förberedelse) = cirka 40 minuter.
Vanliga frågor (FAQ):
Fråga: Är patchen en del av xDoctor-utgåvan?
Svar: Patchinstallationsskriptet är en del av xDoctor release 4.8-84 och senare. Instruktioner för nedladdning av xDoctor och genomförande av patchinstallation finns i lösningsstegen.
Fråga: Kan jag uppdatera flera VDC:er parallellt?
Svar: Nej, korrigera 1 VDC åt gången.
Fråga: Om jag uppgraderar ECS efter att ha kört den här proceduren, kör jag då proceduren igen efter uppgraderingen?
A: Nej, om du uppgraderar till en kodversion som anges i DSA-2022-153 som har den permanenta korrigeringen. Ja, om du uppgraderar till en kodversion som inte anges i samma DSA.
Fråga: Måste korrigeringsfilen appliceras på nytt på ett system där den tidigare installerades efter ett nodbyte, en ny avbildning eller en expansion?
Svar: Nej, om VDC har den kodversion som anges i DSA-2022-153 som har den permanenta korrigeringen. Ja, om du utför någon av dessa åtgärder mot en VDC som kör en kodversion som inte anges i samma DSA. Om korrigeringsfilen krävs för dessa scenarier kontaktar Dell-teknikern i fråga för att informera om att uppdateringen krävs.
Fråga: Vad händer om jag bara använder äldre användare och inte använder IAM?
Svar: Kunder måste tillämpa korrigeringsfilen oavsett om de bara använder äldre användare och inte IAM.
Fråga: Vilken användare ska du vara inloggad som för att köra alla kommandon i denna KB?
A: admin
Q: Måste svc_patch köras på alla rack eller med en specialiserad MACHINES-fil där flera rack finns i en VDC?
Svar: Nej, den identifierar automatiskt om det finns flera rack och korrigerar alla noder på alla rack på den VDC:n.
Fråga: Jag märker att målet xDoctor release inte längre är 4.8-84.0. Varför?
S: xDoctor-utgåvor sker ofta så det rekommenderas alltid att uppgradera till den högsta versionen. Om du tidigare har kört korrigeringen med 4.8-84.0 är systemet däremot helt skyddat mot sårbarheten och behöver inte köras igen.
Sammanfattning av lösning:
Uppgradera din ECS xDoctor-programvara till den senaste tillgängliga versionen.
