SharePoint tokovi posla prestaju da rade kada instalirate .NET bezbednosne ispravke za CVE-2018-8421

Simptomi

Kada instalirate bilo koju od 2018 .NET Framework bezbednosnih ispravki za rešavanje cve-2018-8421 (.NET Framework daljinska ispravka izvršenja), SharePoint tokovi posla koji su u kutiji prestaju da rade. Kada dođe do ovog problema, biće evidentirana stavka greške koja podseća na sledeću:

<Date> <Time> w3wp.exe (0x1868) 0x22FC SharePoint Foundation Workflow Infrastructure 72fs Unexpected RunWorkflow: Microsoft.SharePoint.SPException: <Error><CompilerError Line="-1" Column="-1" Text="Type System.CodeDom.CodeBinaryOperatorExpression is not marked as authorized in the application configuration file." /><CompilerError Line="-1" Column="-1" Text="Type System.CodeDom.CodeBinaryOperatorExpression is not marked as authorized in the application configuration file." /><CompilerError Line="-1" Column="-1" Text="Type System.CodeDom.CodeBinaryOperatorExpression is not marked as authorized in the application configuration file." /><CompilerError Line="-1" Column="-1" Text="Type System.CodeDom.CodeBinaryOperatorExpression is not marked as authorized in the application configuration file." /><CompilerError Line="-1" Column="-1" Text="Type System.CodeDom.CodeBinaryOperatorExpression is not marked as authorized in the application configuration file." /><CompilerError Line="-1" Column="-1" Text="Type System.CodeDom.CodeBinaryOperatorExpression is not marked as authorized in the application configuration file." /><CompilerError Line="-1" Column="-1" Text="Type System.CodeDom.CodeBinaryOperatorExpression is not marked as authorized in the application configuration file." /><CompilerError Line="-1" Column="-1"…

Stavka greške ukazuje na to da je sistem. pogreška u Binaryoperorekkompresija nije uključena u ovlašćene tipove.

Za više informacija o bezbednosnim ispravkama u septembru posetite ovu Microsoft .net blog stranicu.

Uzrok

Workflow Foundation (WF) pokreće tokove posla samo kada su svi zavisni tipovi i sklopovi ovlašćeni u .NET konfiguracionoj datoteci (ili se izričito dodaje kôd) u sledećem stablu:

<configuration>

<System.Workflow.ComponentModel.WorkflowCompiler>

<authorizedTypes>

<targetFx>

Međutim, nakon ažuriranja, neke vrste koje koriste neki od tokova posla SharePoint iz kutije koje ranije nisu bile potrebne su sada potrebne.

Rešenje

Da biste rešili ovaj problem, primenite odgovarajuće ispravke bezbednosti i nebezbednosnih ispravki iz sledećih članaka baze znanja:

4461501 Opis bezbednosne ispravke za SharePoint Enterprise server 2016:13 novembar, 2018 4461508 . novembar 2018, kumulativno ažuriranje za SharePoint Foundation 2013 (KB4461508) 4461510 Novembar 13, 2018, kumulativno ažuriranje za SharePoint Enterprise server 2013 (KB4461510)   4011713 Novembar 13, 2018, ispravka za SharePoint Foundation 2010 (KB4011713) 4461528 Novembar 13, 2018, kumulativno ažuriranje za SharePoint Server 2010 (KB4461528)

Napomene

  • Nakon instaliranja ispravke, čarobnjak za konfigurisanje SharePoint proizvoda mora da se pokrene da bi popravka bila u potpunosti primenjena.

  • Neke radnje sa nezavisnim ili prilagođenim tokovima posla mogu imati dodatne zavisne stavke. Ako naiđete na ponašanje koje je slično ovom problemu, ali ne diskutuje u ovom članku, konsultujte radnju toka posla za pomoć.

Rešenje

Da biste zaobišli ovaj problem, izričito dodajte potrebne tipove u Web. config datoteku svih aplikacija. Iako su obezbeđeni koraci za ručno, preporučujemo da koristite metod skripte. 

Da biste zaobilazili ovaj problem, izričito dodajte potrebne tipove u Web. config datoteke svih aplikacija.

Za SharePoint 2013 i novije verzije

Za SharePoint 2013 i novije verzije dodajte sledeće redove:

Za SharePoint verzije starije od sistema SharePoint 2013

Za SharePoint verzije starije od 2013, dodajte sledeće redove:

Preporučujemo da pokrenete sledeću skriptu umesto direktnog menjanja postojećih datoteka.

Napomena Neki motori za tok posla trećih lica mogu zahtevati Dodavanje dodatnih tipova. U tom slučaju, obratite se dobavljaču za informacije o potrebnim tipovima, a zatim u skladu sa tim podesite skriptu.

Sledeća skripta menja Web. config za sve Web aplikacije da bi dodao potrebne stavke. Ova skripta dodaje ove tipove za postojeće Web aplikacije i za aplikacije koje se kreiraju nakon pokretanja skripte. Skripta treba da se pokreće samo jedanput na bilo kom izloženom Web serveru u farmi (ažurira sve servere).

<#

 This script adds the entries to all web.config files for all web applications in the farm.

 Run this script as Farm Administrator in one of the WFEs.

 This script has to run only one time.

SUMMARY:

This script uses the native SharePoint SPWebConfigModification API to deploy new updates to the web.config file for each web application on each server in the farm.  Servers that are added at a later date will also get the updates applied because the API configuration is persisted in the config database.  This API does not update the web.config for the central administration web application.

If you are running workflows on the central admin web application, you will have to manually update the web.config by using the steps in the referenced blog.
